Method Detail

filter

public void filter(CoordinateSequence seq,
                   int i)

Description copied from interface: CoordinateSequenceFilter

Performs an operation on a coordinate in a CoordinateSequence.

Specified by:

filter in interface CoordinateSequenceFilter

Parameters:

seq - the CoordinateSequence to which the filter is applied

i - the index of the coordinate to apply the filter to

getVertices

public Coordinate[] getVertices()

isDone

public boolean isDone()

Description copied from interface: CoordinateSequenceFilter

Reports whether the application of this filter can be terminated. Once this method returns false, it should continue to return false on every subsequent call.

Specified by:

isDone in interface CoordinateSequenceFilter

Returns:

true if the application of this filter can be terminated.

isGeometryChanged

public boolean isGeometryChanged()

Description copied from interface: CoordinateSequenceFilter

Reports whether the execution of this filter has modified the coordinates of the geometry. If so, Geometry.geometryChanged() will be executed after this filter has finished being executed.

Most filters can simply return a constant value reflecting whether they are able to change the coordinates.

Specified by:

isGeometryChanged in interface CoordinateSequenceFilter

Returns:

true if this filter has changed the coordinates of the geometry
