Specified by:

getEdgeCurrentHPos in interface DataAccess

Parameters:

edge - A constant that represents the edge of interest. The constants end with _EDGE in DataDirector.

This implementation returns 0.

Specified by:

getSliceMemberCount in interface DataAccess

Parameters:

edge - A constant that represents the edge of interest. The constants end with _EDGE in DataDirector.

slice - An absolute index (zero-based) that indicates the location of a slice along the specified edge. Each member in the innermost layer has a unique slice. In outer layers, any slice that the outer member spans can be used.

Retrieves the starting logical layer of a specified slice in a specified edge when the Crosstab (along with the DataAccess implementor) is set to return data in outline mode. Because, in outline mode, the getSliceMemberCount method always return the value 1, the Crosstab uses getSliceOutlineLayer to determine the logical layer.

This implementation returns 0.

Specified by:

getSliceOutlineLayer in interface DataAccess

Parameters:

edge - A constant that represents the edge of interest. The constants end with _EDGE in DataDirector. The slice is zero-based. Each member in the innermost layer has a unique slice. In outer layers, any slice that the outer member spans can be used.

slice - An absolute index (zero-based) that indicates the location of a slice along the specified edge. Each member in the innermost layer has a unique slice. In outer layers, any slice that the outer member spans can be used.

Returns:

The logical layer of the specified slice in the specified edge for outline mode only. This implementation returns zero.

Throws:

EdgeOutOfRangeException - If the edge parameter is not valid.

SliceOutOfRangeException - If slice is negative or too large.

                          LayerOutOfRangeException,
                          SliceOutOfRangeException

Retrieves the size (expressed in layers that are perpendicular to the specified edge orientation) of a member at the specified layer, slice, and edge. In other words, this method returns the following information depending upon the specified edge:

• Returns the "height" of a member in the Crosstab's column edge header, that is, the number of heading rows for the member.
• Returns the "width" of a member in the Crosstab's row edge header, that is the number of heading columns for the member.

The sum of all the members' values for this method, within a specified slice, should not exceed the value that getLayerCount returns for the specified edge.

This method is useful only in cases of asymmetry where the members on an edge do not all cover one layer and have a depth of 1. On a symmetric edge, all members have a member depth of 1.

This implementation returns 0.

Specified by:

getMemberDepth in interface CDFDataAccess

Parameters:

edge - A constant that represents the edge in which to look for the layer and slice. The constants end with _EDGE in DataDirector.

layer - The zero-based index of the starting physical layer in which to look for the slice, as returned by getMemberStartLayer.

slice - An absolute index (zero-based) that indicates the location of a slice along the specified edge. Each member in the innermost layer has a unique slice. In outer layers, any slice that the outer member spans can be used.

Returns:

The depth (that is, the number of layers) that the specified member covers. This implementation returns zero.

Throws:

EdgeOutOfRangeException - If edge is too large.

LayerOutOfRangeException - If layer is negative or too large.

SliceOutOfRangeException - If slice is negative or too large.

                               SliceOutOfRangeException

Retrieves the starting layer at which a member at the specified edge, layer, and slice location begins. Presentation beans use this method in conjunction with getMemberDepth to retrieve the following information depending on the edge:

• For a member on a column edge, the vertical height and starting position.
• For a member on a row edge, the horizontal width and starting position.

The sum of the values that are returned for a member by this method, getMemberStartLayer, and getMemberDepth should not exceed the value that is returned by getLayerCount for an edge.

This method is useful only in cases of asymmetry where the members on an edge do not all cover one layer. In a symmetric edge, all members have a member start layer equal to their layer.

Specified by:

getMemberStartLayer in interface CDFDataAccess

Parameters:

edge - A constant that represents the edge in which to look for layer and slice. The constants end with _EDGE in DataDirector.

layer - The zero-based index of the physical layer in which to look for the slice.

slice - An absolute index (zero-based) that indicates the location of a slice along the specified edge. Each member in the innermost layer has a unique slice. In outer layers, any slice that the outer member spans can be used.

Returns:

The starting layer of the member within the specified edge.

Throws:

EdgeOutOfRangeException - If edge is too large.

LayerOutOfRangeException - If layer is negative or too large.

SliceOutOfRangeException - If slice is negative or too large.

                          throws EdgeOutOfRangeException,
                                 LayerOutOfRangeException,
                                 SliceOutOfRangeException

Retrieves the count of all the sibling members at a specified logical layer based on a series of relative indexes for each logical layer down to the specified logical layer. This method is useful in populating a page control for a view. For an example, consider the following column header.

June							July
Tents			Canoes				Tents			Canoes
NY	Boston	LA	Toronto	Winnepeg	NY	LA	NY	Boston	LA	Toronto	Winnepeg

A caller can use this method to find the number of Geography values (that is, sibling members) under the members July and Tents. This count is 3 (for NY, Boston, and LA). The hPos and memberLayer parameters for this example are as follows:

• hPos, an array of relative indexes, holds an entry for July, Tents, and any one of the siblings that are to be counted. A valid hPos in this example must contain indexes for at least layers 0, 1, and 2. Valid arrays for this example could be any of the following: {1,0,0} or {1,0,1} or {1,0,2).
• memberLayer, which identifies the layer at which to count the siblings, must be 2.

Note: The value that is returned by this method provides the upper limit to the hIndex that a caller passes in getMemberMetadata.

This implementation returns 0.

Specified by:

getMemberSiblingCount in interface DataAccess

Parameters:

edge - A constant that represents the edge of interest. The constants end with _EDGE in DataDirector.

hPos - An array that contains an index for the member values at each layer up to and including the layer of the sibling members that are to be counted. These indexes are relative to the number of members at each layer. When a member spans more than one layer, any layers beyond the starting layer should have their place held by a -1 index.

memberLayer - The index into the hPos array for which the call should return the sibling member count.

Returns:

The number of sibling members that are found on the specified edge at the location that is specified by hPos and memberLayer. In the example, this method returns 3 (for the siblings NY, Boston, and LA). This implementation returns 0.

Throws:

EdgeOutOfRangeException - If edge is too large.

LayerOutOfRangeException - If memberLayer is too large.

SliceOutOfRangeException - If any slice in hPos is too large.

Retrieves the specified type of metadata for the member at a specified location. For example, this method is useful for retrieving labels for display in views.

The user of this method makes the following calls:

• Calls getMemberSiblingCount to retrieve the number of sibling members for a specified tree of members.
• Calls this method once for each sibling member to retrieve the specified metadata for that member.

The call for this method uses the same hPos and memberLayer parameters as found in getMemberSiblingCount to specify the parent tree of members. Each call of this method also uses the hIndex parameter that indicates the specific sibling member for which to return metadata. Valid values for hIndex range from 0 to (getMemberSiblingCount() - 1).

Specified by:

getMemberMetadata in interface DataAccess

Parameters:

edge - A constant that represents the edge of interest. The constants end with _EDGE in DataDirector.

hPos - An array of relative indexes, organized by logical layer, for the parent tree of members above the sibling member that is specified by hIndex. The array includes entries for layer 0 through at least the layer that is specified by memberLayer.

memberLayer - The zero-based index into the hPos array for which the call should address the set of sibling members.

hIndex - The zero-based index of a sibling member relative to its siblings. This index specifies the sibling member for which to return the specified metadata.

type - A constant that specifies the kind of metadata to return. Valid type values are defined in MetadataMap.

Returns:

The requested metadata for the member at the specified location. This implementation returns null.

Throws:

EdgeOutOfRangeException - If edge is too large.

LayerOutOfRangeException - If memberLayer is too large.

SliceOutOfRangeException - If any slice in hPos is too large, or if the hIndex is too large.

                    throws EdgeOutOfRangeException,
                           LayerOutOfRangeException,
                           SliceOutOfRangeException

Retrieves the hierarchical address for an absolute address that is specified as edge, physical layer, and slice. This method constructs an array that can be used in creating the hPos parameter in calls such as getMemberSiblingCount and getMemberMetadata.

As an example, this method can retrieve an array of indexes from a page edge. The array includes an index for each layer in the page edge. Consider pivoting the following column header to a page edge.

June							July
Tents			Canoes				Tents			Canoes
NY	Boston	LA	Toronto	Winnepeg	NY	LA	NY	Boston	LA	Toronto	Winnepeg

If the current page displayed June, Canoes, and Winnepeg, this method would return the array {0,1,1}. June is at index 0 in layer 0. Canoes is at index 1 in layer 1 under June. Winnepeg is at index 1 in layer 2 under Canoes. To find the number of members under Canoes under June, call getMemberSiblingCount with the array {0,1,1} and the memberLayer parameter 2.

Parameters:

qdr - QDR representing a position (edge member, edge slice, or data cell)

startSlice - optional set of slices, ordered by edge (column edge 0, row edge 1, etc.), specifying the beginning of a viewport within which getSlicesFromQDR should check for the QDR. endSlices optional set of slices, ordered by edge (see startSlices), specifying the end of a viewport within which getSlicesFromQDR should check for the QDR.

Returns:

the location of the given QDR as an array of absolute slice positions, ordered by edge. If there is no edge in a particular set of data, the slice value will be -1 in that array position. If the QDR cannot be located or cannot be located within the given viewport if specified, -1 values will be returned. If the method is not implemented, null is returned.

release

public void release()

Informs the implementor that the caller no longer needs this DataAccess reference. Provides an opportunity for cleaning up the cursor when a caller is finished with it.

Views should not call this method for normal DataAccess instances, because calling this method makes the DataAccess reference unavailable to other presentation beans that might be using it. This method is useful only in special cases where a caller has wrapped a DataAccess around a private single-layer cursor.

The implementor may or may not implement this method, depending on the underlying cursor.

Description copied from interface: DataAccess

Returns an unordered List of Object arrays representing metadata for unique member values across a layer on an edge. The Object arrays correspond one-to-one with the MetadataMap types specified in the types parameter. An example of a types array might be: new String[] {MetadataMap.METADATA_VALUE, MetadataMap.METADATA_LONGLABEL} In this case, the method would return the unique set of values and their longlabels found across the given layer on the given edge. This list will be complete if the layer does not depend on any other layers (symmetric). If it is asymmetric, the number of items scanned will be constrained by no more than count number of unique items or an implementation-dependent limitation on the number of outer layer parents scanned. The return value might be: listElement(0) = new Object[] {"TOTALPROD", "Total Products"} listElement(1) = new Object[] {"AUDIODIV", "Audio Division"} listElement(2) = new Object[] {"CAMCORDER", "Camcorder"}\ If start were 1 and count were -1, then only listElement items 1 and 2 would be returned as the 0th and 1th items in the List. Normally, start will be 0 and count will be -1.

Specified by:

getUniqueMemberMetadata in interface DataAccess

Parameters:

edge - The edge containing the layer for which to build the member list

layer - The zero-based index of the physical layer for which to build the member list

types - An array of MetadataMap types indicating the nature of the returned metadata in the Vector elements

start - Starting point in the overall unique member list of the return list. Zero indicates start from the beginning.

count - Maximum number of unique values to return, beginning at index start. -1 indicates all values should be returned. Ignored in symmetric cases. The caller is free to ignore values returned beyond their requested count if they are managing fixed size virtual buffers.

Returns:

a Vector of Object arrays, with each element of the Vector representing one unique member for the given edge and layer. Each element of the Object array corresponds to the metadata specified one-for-one in the types parameter.

Throws:

EdgeOutOfRangeException - If edge is too large.

This implementation does nothing.

Specified by:

addDataDirectorListener in interface DataDirector

Parameters:

l - The listener to add.

removeDataDirectorListener

public void removeDataDirectorListener(DataDirectorListener l)

Removes a listener from the data source.

This implementation does nothing.

setOutline

public void setOutline(boolean outline)
                throws DataDirectorException

Specifies whether data is provided to a view in outline form. Updates the data and fires a DataChanged event. This is an optional method because implementors that do not require an outline display do not have to support outline form. Outline form lists outer layers in the same depth as inner layers, whereas inline form shows outer layers at different depths.

For example, if the row edge uses outline form, all layers appear in the same label column. If the row edge does not use outline form, then there is a separate column for each layer.

This implementation does nothing.

Specified by:

setOutline in interface DataDirector

Parameters:

outline - true to specify outline form for data, false to use inline form for data.

Throws:

DataDirectorException - If a data provider error occurs

isOutline

public boolean isOutline()

Indicates whether data is provided in outline form or inline form. Outline form lists outer layers in the same depth as inner layers, whereas inline form shows outer layers at different depths. This method should always return false if the implementor does not support outline form.

In a Crosstab, for example, if a row edge uses outline form, then all layers appear in the same label column. If a row edge does not use outline form, then there is a separate column for each layer.

This implementation returns false.

Specified by:

isOutline in interface DataDirector

Returns:

true if the data is provided in outline form, false if the data is provided in inline form.

Description copied from interface: DataAccess

Determines if the size of a member, that is, the number of slices that the member spans at a specified edge, layer, and slice location (parallel to the direction of the edge), has been completely calculated. Views use this method to determine whether the width of a member in a column header or the height of a member in a row header when not in outline form will increase further, in order for views to support dynamic span information from implementations.

Specified by:

isMemberExtentComplete in interface DataAccess

Parameters:

edge - A constant that represents the edge in which to look for the layer and slice. The constants end with _EDGE in DataDirector.

layer - The zero-based number of the physical layer. Valid values are zero to total layers at the specified slice.

slice - An absolute index (zero-based) along the edge. Each member in the innermost layer has a unique slice. In outer layers, any slice that the outer member spans can be used.

Returns:

true if the extent of the specified member has been fully computed, false if not.

Throws:

EdgeOutOfRangeException - If edge is too large.

LayerOutOfRangeException - If layer is negative or too large.

SliceOutOfRangeException - If slice is negative or too large.

Description copied from interface: DataDirector

Sets a piece of metadata for a logical layer that is found at a specified edge, logical layer and LayerMetadataMap type. Calling this method may result in a DataChangedEvent, and may result in the new metadata being shared by others users of the DataAccess/DataDirector implementation. The changes may or may not be persisted if the DataDirector implementation is persistable. As a rule, only Strings, Booleans, Integers, Longs, Floats and Doubles will be persisted if at all.

Specified by:

setLayerMetadata in interface DataDirector

Parameters:

edge - A constant that represents the edge of interest. The constants end with _EDGE in DataDirector.

layer - The zero-based number of the layer for which metadata is to be set. Uses a depth computation to identify the location of the layer or layer member; 0 is the outer-most layer on the edge. The value for this parameter can be obtained by calling getMemberLogicalLayer.

type - A constant that specifies the kind of metadata that you want to set. Valid type values are defined in the LayerMetadataMap.

value - The new value for the metadata at the given edge, layer, and type. null clears the setting for the edge, layer, and type.

Throws:

EdgeOutOfRangeException - If edge is too large.

LayerOutOfRangeException - If layer is negative or too large.
