createSubGeomArray

protected Geometry[] createSubGeomArray(int ngeoms)

Description copied from class: ComposedGeom

Return the appropriate instance of the sub-geometry array - this encapsulates subclass specific array instantiation

Specified by:

createSubGeomArray in class ComposedGeom

Parameters:

ngeoms - number of elements in the array

Returns:

Geometry array corresponding to the sub-geometry

createSubGeomInstance

Description copied from class: ComposedGeom

Return the appropriate instance of the sub-geometry - this encapsulates subclass specific constructor calls

Specified by:

createSubGeomInstance in class ComposedGeom

Parameters:

token - The token containing the value for the sub-geometry

haveM - flag to indicate the existence of a measure

Returns:

the new sub-geometry

Throws:

SQLException - if a SQLException is thrown

innerWKT

protected void innerWKT(StringBuffer SB)

Description copied from class: Geometry

Render the "inner" part of the WKT (inside the brackets) into the StringBuffer.

Overrides:
