public class SdoGeorAggrPKG
extends java.lang.Object

SdoGeorAggrPKG is a Java class which wraps PL/SQL functions and procedures defined in the server-side package SDO_GEOR_AGGR. When a method defined in the class is invoked, a corresponding PL/SQL block is generated and submitted to the target Oracle database through a JDBC connection, so that equivalent result by PL/SQL can be achieved from the Java side.

Note that all methods in this class are transactional, which means that no commit statement is issued implicitly in each method.

The following is an example of how to use this class:

   //initialize an instance of SdoGeorAggrPKG
   SdoGeorAggrPKG  pkg=new SdoGeorAggrPKG(connection);
   //reading a GeoRaster object from database based on a query
   Statement stmt = connection.createStatement();
   ResultSet rs = statement.executeQuery("SELECT a.georaster FROM georaster_table a where a.georaster.rasterdatatable='RDT' and a.georaster.rasterid=1");
   rs.next();
   STRUCT geor = (oracle.sql.STRUCT) rs.getObject(1);
   //convert STRUCT into SdoGeoRaster
   SdoGeoRaster sdoGeoRaster = new SdoGeoRaster(geor);
   rs = statement.executeQuery("SELECT a.georaster FROM georaster_table a where a.georaster.rasterdatatable='RDT' and a.georaster.rasterid=2");
   rs.next();
   geor = (oracle.sql.STRUCT) rs.getObject(1);
   //convert STRUCT into SdoGeoRaster
   SdoGeoRaster sdoGeoRaster1 = new SdoGeoRaster(geor);
   //Appends the source GeoRaster object to the target GeoRaster object.
   pkg.append(sdoGeoRaster,sdoGeoRaster1,0,null,null);

                   java.lang.Integer sourcePyramidLevel,
                   java.lang.String appendParam,
                   double[] bgValues)
            throws java.lang.Exception
```
    Appends the source GeoRaster object to the target GeoRaster object. Internal rectification, common point rules, gap filling, and color balancing are performed whenever necessary.
    
    Parameters:
    
    targetGeoRaster - GeoRaster object to be updated. Cannot be the same as sourceGeoRaster. (Be sure to make a copy of this object before you update it.)
    
    sourceGeoRaster - GeoRaster object to be appended to targetGeoRaster.
    
    sourcePyramidLevel - Pyramid level of the source GeoRaster object to be appended at the target GeoRaster object pyramid Level 0. If NULL, pyramid level 0 is used.
    
    appendParam - A comma-separated quoted string of keyword=value pairs for specifying parameters for the operation. It can contain one or more of the keywords in Table 8-1 "mosaicParam Keywords" of Spatial GeoRaster Developer's Guide in the SDO_GEOR_AGGR.mosaicSubset reference section. If a nondefault value for colorBalance is specified, it is performed on the source GeoRaster object using the target GeoRaster object's statistics as the reference, and the following keywords (if specified) are ignored: maxVal, minVal, std, and min.
    
    bgValues - Background values for filling partially empty raster blocks. It is only useful when the source GeoRaster object has empty raster blocks and the current operation leads to partially empty raster blocks (see Section 1.4.4 of Spatial GeoRaster Developer's Guide). The number of elements in the SDO_NUMBER_ARRAY object must be either one (same filling value used for all bands) or the band dimension size (a different filling value for each band, respectively). For example, SDO_NUMBER_ARRAY(1,5,10) fills the first band with 1, the second band with 5, and the third band with 10. The default bgValues are zero (0). The filling values must be valid cell values as specified by the target cell depth background values for filling sparse data.

    inGeoRasters - SQL query string for the input GeoRaster objects.
    
    pyramidLevel - Pyramid level of the source GeoRaster objects for the operation. This parameter is used when the outResolutions parameter is not specified; otherwise, the pyramid level of the source GeoRaster objects is determined by the outResolutions parameter.
    
    outSRID - Coordinate system for the output GeoRaster object. Must be either null or a value from the SRID column of the MDSYS.CS_SRS table.
    
    outModelCoordLoc - A value specifying the model location of the base of the area represented by a cell: 0 for CENTER or 1 for UPPERLEFT. If null, CENTER is used.
    
    referencePoint - A point in JGeometry type used as the reference point of mosaic. If a point is specified, the mosaicked image's upper left corner aligns with the reference point, that is, the distance between the referencePoint and the upper-left corner of the output will have an integer number of pixels. If this parameter is null, the reference point implicitly uses the upper-left corner of the cropArea, or when the cropArea is null, the upper-left corner of the output extent.
    
    cropArea - Crop area definition. If the JGeometry object has a non-null SRID, the source GeoRaster objects must be georeferenced; otherwise, the source GeoRaster objects can be georeferenced or non-georeferenced. If polygonClip is FALSE, the MBR of the cropArea is used to crop the mosaicked data. If polygonClip is TRUE, the geometry of the cropArea is used to crop the mosaicked data.
    
    polygonClip - The TRUE causes the cropArea value to be used to crop the mosaicked data; the FALSE causes the MBR of the cropArea to be used to crop the mosaicked data.
    
    boundaryClip - The TRUE causes the boundary of the virtual mosaic to be used to clip the cropArea; the FALSE causes the area that is outside the virtual mosaic but within the cropArea to be filled with the background value.
    
    layerNumbers - A string identifying the logical layer numbers on which the operation or operations are to be performed. Use commas to delimit the values, and a hyphen to indicate a range (for example, 2-4 for layers 2, 3, and 4). If not specified, the mosaic result contains the same number of bands as the source GeoRaster objects.
    
    outResolutions - Resolution requested for the output GeoRaster data. If null, the default is the resolution of the first encountered GeoRaster object. See the Usage Notes for details.
    
    resolutionUnit - The unit of the outResolutions parameter. If null, the default is the unit of the output SRID. If specified, it must be a quoted string in the format "unit=value" where value is the unit name. This parameter is ignored if outResolutions is null.
    
    mosaicParam - A comma-separated quoted string of keyword=value pairs for specifying mosaic parameters. It can contain one or more of the keywords in Table 8-1, "mosaicParam Keywords" in the SDO_GEOR_AGGR.mosaicSubset reference section.
    
    outArea - Geometry object that describes the extent of the output data.
    
    outWindow - An array to hold the coordinates of the upper-left and lower-right corners of the output window in the cell space.
    
    storageParam - A string specifying storage parameters, as explained in Section 1.4.1. If this parameter is null, the resulting GeoRaster object has the same storage parameters (blockSize, cellDepth, interleaving, and compression) as the first encountered source GeoRaster object in the model space (if applicable) or cell space. However, it is recommended that you specify the storage parameters, particularly the blocking size, as appropriate for the size of the output mosaic, unless you want the mosaic to have the same storage parameters as those of the first encountered GeoRaster object to be mosaicked.
    
    bgValues - Background values for filling partially empty raster blocks. It is only useful when the source GeoRaster object has empty raster blocks and the current operation leads to partially empty raster blocks (see Section 1.4.4). The number of elements in the SDO_NUMBER_ARRAY object must be either one (same filling value used for all bands) or the band dimension size (a different filling value for each band, respectively). For example, SDO_NUMBER_ARRAY(1,5,10) fills the first band with 1, the second band with 5, and the third band with 10. The default bgValues are zero (0).
    
    Returns:
    
    an BLOB (binary large object) to hold the result of the operation.

    Parameters:
    
    inGeoRasters - SQL query string for the input GeoRaster objects.
    
    pyramidLevel - Pyramid level of the source GeoRaster objects for the operation. This parameter is used when the outResolutions parameter is not specified; otherwise, the pyramid level of the source GeoRaster objects is determined by the outResolutions parameter.
    
    elevationParam - A string containing one or more of the elevation parameter average (average surface height). This parameter must be a quoted string that contains a keyword=value pair (for example, 'average=800'). This parameter specifies the elevation of the output GeoRaster object. If this parameter is null, 0 is assumed for average. The use of the elevationParam parameter requires that the input GeoRaster objects have a 3D model SRID.
    
    outSRID - Coordinate system for the output GeoRaster object. Must be either null or a value from the SRID column of the MDSYS.CS_SRS table.
    
    outModelCoordLoc - A value specifying the model location of the base of the area represented by a cell: 0 for CENTER or 1 for UPPERLEFT. If null, CENTER is used.

If a point is specified, the mosaicked image's upper left corner aligns with the reference point, that is, the distance between the referencePoint and the upper-left corner of the output will have an integer number of pixels. If this parameter is null, the reference point implicitly uses the upper-left corner of the cropArea, or when the cropArea is null, the upper-left corner of the output extent.
    
    cropArea - Crop area definition.

If polygonClip is FALSE, the MBR of the cropArea is used to crop the mosaicked data. If polygonClip is TRUE, the geometry of the cropArea is used to crop the mosaicked data.
    
    polygonClip - The TRUE causes the cropArea value to be used to crop the mosaicked data; the FALSE value causes the MBR of the cropArea to be used to crop the mosaicked data.

    layerNumbers - A string identifying the logical layer numbers on which the operation or operations are to be performed. Use commas to delimit the values, and a hyphen to indicate a range (for example, 2-4 for layers 2, 3, and 4).

If this parameter is null, the resulting GeoRaster object has the same storage parameters (blockSize, cellDepth, interleaving, and compression) as the first encountered source GeoRaster object in the model space (if applicable) or cell space. However, it is recommended that you specify the storage parameters, particularly the blocking size, as appropriate for the size of the output mosaic, unless you want the mosaic to have the same storage parameters as those of the first encountered GeoRaster object to be mosaicked.
    
    bgValues - Background values for filling partially empty raster blocks. It is only useful when the source GeoRaster object has empty raster blocks and the current operation leads to partially empty raster blocks (see Section 1.4.4).

    referenceImage - Specifies the reference image used during the color balance operation. If null, it defaults to the first image from the query.
    
    referenceValue1 - Specifies the reference value or values used during the color balance operation. The meaning of the values is determined by the color balance method.
    
    referenceValue2 - Specifies the reference value or values used during the color balance operation. The meaning of the values is determined by the color balance method.
    
    referenceHistograms - Specifies the reference histograms used during the color balance operation.

    referenceImage - Specifies the reference image used during the color balance operation. If null, it defaults to the first image from the query.
    
    referenceValue1 - Specifies the reference value or values used during the color balance operation. The meaning of the values is determined by the color balance method.
    
    referenceValue2 - Specifies the reference value or values used during the color balance operation. The meaning of the values is determined by the color balance method.
    
    referenceHistograms - Specifies the reference histograms used during the color balance operation.

    Performs advanced large-scale mosaicking or subsetting from a virtual mosaic or a collection of GeoRaster objects. The output data is written into a GeoRaster object for persistent storage or other processing. Internal rectification, common point rules, gap filling, and color balancing are performed whenever necessary.
    
    Parameters:
    
    inGeoRasters - SQL query string for the input GeoRaster objects. corresponding to the table names in georasterTableNames.
    
    pyramidLevel - Pyramid level of the source GeoRaster objects for the operation. This parameter is used when the outResolutions parameter is not specified; otherwise, the pyramid level of the source GeoRaster objects is determined by the outResolutions parameter.
    
    outSRID - Coordinate system for the output GeoRaster object. Must be either null or a value from the SRID column of the MDSYS.CS_SRS table.
    
    outModelCoordLoc - A value specifying the model location of the base of the area represented by a cell: 0 for CENTER or 1 for UPPERLEFT. If null, CENTER is used.
    
    referencePoint - A point in JGeometry type used as the reference point of mosaic. If a point is specified, the mosaicked image's upper left corner aligns with the reference point, that is, the distance between the referencePoint and the upper-left corner of the output will have an integer number of pixels. If this parameter is null, the reference point implicitly uses the upper-left corner of the cropArea, or when the cropArea is null, the upper-left corner of the output extent.
    
    cropArea - Crop area definition. If the JGeometry object has a non-null SRID, the source GeoRaster objects must be georeferenced; otherwise, the source GeoRaster objects can be georeferenced or non-georeferenced. If polygonClip is FALSE, the MBR of the cropArea is used to crop the mosaicked data. If polygonClip is TRUE, the geometry of the cropArea is used to crop the mosaicked data.
    
    polygonClip - The TRUE causes the cropArea value to be used to crop the mosaicked data; the FALSE causes the MBR of the cropArea to be used to crop the mosaicked data.
    
    boundaryClip - The TRUE causes the boundary of the virtual mosaic to be used to clip the cropArea; the FALSE causes the area that is outside the virtual mosaic but within the cropArea to be filled with the background value.
    
    layerNumbers - A string identifying the logical layer numbers on which the operation or operations are to be performed. Use commas to delimit the values, and a hyphen to indicate a range (for example, 2-4 for layers 2, 3, and 4). If not specified, the mosaic result contains the same number of bands as the source GeoRaster objects.
    
    outResolutions - Resolution requested for the output GeoRaster data. If null, the default is the resolution of the first encountered GeoRaster object. See the Usage Notes for details.
    
    resolutionUnit - The unit of the outResolutions parameter. If null, the default is the unit of the output SRID. If specified, it must be a quoted string in the format "unit=value" where value is the unit name. This parameter is ignored if outResolutions is null.
    
    mosaicParam - A comma-separated quoted string of keyword=value pairs for specifying mosaic parameters. It can contain one or more of the keywords in Table 8-1, "mosaicParam Keywords" in the SDO_GEOR_AGGR.mosaicSubset reference section.
    
    storageParam - A string specifying storage parameters, as explained in Section 1.4.1. If this parameter is null, the resulting GeoRaster object has the same storage parameters (blockSize, cellDepth, interleaving, and compression) as the first encountered source GeoRaster object in the model space (if applicable) or cell space. However, it is recommended that you specify the storage parameters, particularly the blocking size, as appropriate for the size of the output mosaic, unless you want the mosaic to have the same storage parameters as those of the first encountered GeoRaster object to be mosaicked.
    
    outGeoRaster - Output GeoRaster object
    
    bgValues - Background values for filling partially empty raster blocks. It is only useful when the source GeoRaster object has empty raster blocks and the current operation leads to partially empty raster blocks (see Section 1.4.4). The number of elements in the SDO_NUMBER_ARRAY object must be either one (same filling value used for all bands) or the band dimension size (a different filling value for each band, respectively). For example, SDO_NUMBER_ARRAY(1,5,10) fills the first band with 1, the second band with 5, and the third band with 10. The default bgValues are zero (0).
    
    parallelDegree - Specifies the degree of parallelism for the operation. If >1. The database optimizer uses the degree of parallelism specified by this parameter. If <=1, then there is no parallel processing. (For more information,see Section 1.13 of Spatial GeoRaster Developer's Guide, "Parallel Processing in GeoRaster"). If parallelism is specified, the procedure performs an internal commit operation. If an error occurs (even if it is raised by the Oracle parallel server), you must delete the resulting mosaicked GeoRaster object explicitly in order to roll back the operation.

    outResolutions - Resolution requested for the output GeoRaster data. If null, the default is the resolution of the first encountered GeoRaster object. See the Usage Notes for details.
    
    resolutionUnit - The unit of the outResolutions parameter. If null, the default is the unit of the output SRID. If specified, it must be a quoted string in the format "unit=value" where value is the unit name. This parameter is ignored if outResolutions is null.
    
    mosaicParam - A comma-separated quoted string of keyword=value pairs for specifying mosaic parameters. It can contain one or more of the keywords in Table 8-1, "mosaicParam Keywords" in the SDO_GEOR_AGGR.mosaicSubset reference section.
    
    storageParam - A string specifying storage parameters, as explained in Section 1.4.1. If this parameter is null, the resulting GeoRaster object has the same storage parameters (blockSize, cellDepth, interleaving, and compression) as the first encountered source GeoRaster object in the model space (if applicable) or cell space. However, it is recommended that you specify the storage parameters, particularly the blocking size, as appropriate for the size of the output mosaic, unless you want the mosaic to have the same storage parameters as those of the first encountered GeoRaster object to be mosaicked.
    
    outGeoRaster - Output GeoRaster object
    
    bgValues - Background values for filling partially empty raster blocks. It is only useful when the source GeoRaster object has empty raster blocks and the current operation leads to partially empty raster blocks (see Section 1.4.4). The number of elements in the SDO_NUMBER_ARRAY object must be either one (same filling value used for all bands) or the band dimension size (a different filling value for each band, respectively). For example, SDO_NUMBER_ARRAY(1,5,10) fills the first band with 1, the second band with 5, and the third band with 10. The default bgValues are zero (0).
    
    parallelDegree - Specifies the degree of parallelism for the operation. If >1. The database optimizer uses the degree of parallelism specified by this parameter. If <=1, then there is no parallel processing. (For more information,see Section 1.13 of Spatial GeoRaster Developer's Guide, "Parallel Processing in GeoRaster"). If parallelism is specified, the procedure performs an internal commit operation. If an error occurs (even if it is raised by the Oracle parallel server), you must delete the resulting mosaicked GeoRaster object explicitly in order to roll back the operation.
    
    referenceImage - Specifies the reference image used during the color balance operation. If null, it defaults to the first image from the query.
    
    referenceValue1 - Specifies the reference value or values used during the color balance operation. The meaning of the values is determined by the color balance method.
    
    referenceValue2 - Specifies the reference value or values used during the color balance operation. The meaning of the values is determined by the color balance method.
    
    referenceHistograms - Specifies the reference histograms used during the color balance operation.
