Method Detail

filter

public void filter(com.vividsolutions.jts.geom.CoordinateSequence seq,
                   int i)

Specified by:

filter in interface com.vividsolutions.jts.geom.CoordinateSequenceFilter

getDimension

public int getDimension()

Gets the dimension of the coordinate sequence.

Returns:

a integer between 2 and 4.

isMixed

public boolean isMixed()

is2D

public boolean is2D()

setMAXDim

public void setMAXDim(int maxDim)

Sets the maximum allowed dimension for the filter. The filter will stop after this dimension has been reached. Possible values are: CoordinateSequenceDimensionFilter.XY CoordinateSequenceDimensionFilter.XYZ CoordinateSequenceDimensionFilter.XYZM Default value is: CoordinateSequenceDimensionFilter.XYZM.

Parameters:

maxDim - a integer dimension

isDone

public boolean isDone()

Specified by:

isDone in interface com.vividsolutions.jts.geom.CoordinateSequenceFilter

isGeometryChanged

public boolean isGeometryChanged()

Specified by:

isGeometryChanged in interface com.vividsolutions.jts.geom.CoordinateSequenceFilter
