Method Detail

toJGeometry

JGeometry toJGeometry(byte[] wkContent)
               throws GeometryExceptionWithContext

This transforms a WKB/WKT geometry to a JGeometry.

Parameters:

wkContent - a byte[] representing the WKB/WKT geometry

Returns:

a JGeometry representing the Oracle Spatial geometry

Throws:

GeometryExceptionWithContext

fromJGeometry

byte[] fromJGeometry(JGeometry geom)
              throws GeometryExceptionWithContext

This transforms a JGeometry to a WKB/WKT geometry.

Parameters:

geom - a JGeometry representing the Oracle Spatial geometry

Returns:

a byte[] representing the WKB/WKT geometry

Throws:

GeometryExceptionWithContext

toSTRUCT

STRUCT toSTRUCT(byte[] wkContent,
                java.sql.Connection conn)
         throws java.sql.SQLException,
                GeometryExceptionWithContext

Convert the given WKB/WKT geometry into an Oracle JDBC STRUCT object. You can then bind the STRUCT object to a SQL DML statment.

Parameters:

wkContent - the WKB/WKT geometry (byte array) to be converted

conn - the connection to be used

Returns:

an Oracle STRUCT object when successful; otherwise null

Throws:

java.sql.SQLException

GeometryExceptionWithContext

fromSTRUCT

byte[] fromSTRUCT(STRUCT geom)
           throws java.sql.SQLException,
                  GeometryExceptionWithContext

Creates a WKB/WKT geometry from a STRUCT object.

Parameters:

geom - the STRUCT object from an oracle result set

Returns:

a WKB/WKT geometry (byte array) if successful; otherwise null

Throws:

java.sql.SQLException

GeometryExceptionWithContext
