Method Detail

addPoint

public void addPoint(Point gmp)

adds a Point to the aggregation

Specified by:

addPoint in interface MultiPoint

insertPointAt

public void insertPointAt(Point gmp,
                          int index)
                   throws GeometryException

inserts a Point into the aggregation. all elements with an index equal or larger index will be moved. if index is larger then getSize() - 1 or smaller then 0 or gmp equals null an exception will be thrown.

Specified by:

insertPointAt in interface MultiPoint

Parameters:

gmp - Point to insert.

index - position where to insert the new Point

Throws:

GeometryException

removePoint

public Point removePoint(Point gmp)

removes the submitted Point from the aggregation

Specified by:

removePoint in interface MultiPoint

Parameters:

gmp - to remove

Returns:

the removed Point

removePointAt
