getErrorInfo

public boolean getErrorInfo()

invoke

public EditableFeature invoke(Geometry g,
                              Feature feature)

clips feature's geometry with the clipping geometry, preserving feature's original attributes. If feature's geometry doesn't touch clipping geometry, it will be ignored.

Specified by:

invoke in class GeometryOperation

Returns:
