filter
Description copied from interface:CoordinateSequenceFilter
Performs an operation on a coordinate in aCoordinateSequence
.- Specified by:
filter
in interfaceCoordinateSequenceFilter
- Parameters:
seq
- theCoordinateSequence
to which the filter is appliedi
- the index of the coordinate to apply the filter to
-
getNearestPoint
-
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 interfaceCoordinateSequenceFilter
- 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 interfaceCoordinateSequenceFilter
- Returns:
- true if this filter has changed the coordinates of the geometry
