Constructor Detail

PointExtracter

public PointExtracter(java.util.List pts)
Constructs a PointExtracterFilter with a list in which to store Points found.

Method Detail

getPoints

public static java.util.List getPoints(Geometry geom)
Returns the Point components from a single geometry. If more than one geometry is to be processed, it is more efficient to create a single PointExtracterFilter instance and pass it to multiple geometries.


filter

public void filter(Geometry geom)
Description copied from interface: GeometryFilter
Performs an operation with or on geom.

Specified by:
filter in interface GeometryFilter
Parameters:
geom - a Geometry to which the filter is applied.
