invoke

public EditableFeature invoke(Geometry g,
                     Feature featureInput)

Computes intersection between the geometry and the overlay layer. The fields of the intersected features will be added.

Specified by:

invoke in class GeometryOperation

Parameters:

g -

featureInput -

Returns:

invoke

public void invoke(Geometry g,
          EditableFeature featureInput)

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.
