Method Detail

addSurface

public void addSurface(Surface gms)

adds an Surface to the aggregation

Specified by:

addSurface in interface MultiSurface

insertSurfaceAt

public void insertSurfaceAt(Surface gms,
                            int index)
                     throws GeometryException

inserts a Surface in 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 gms equals null an exception will be thrown.

Specified by:

insertSurfaceAt in interface MultiSurface

Parameters:

gms - Surface to insert.

index - position where to insert the new Surface

Throws:

GeometryException

setSurfaceAt

removeSurface

public Surface removeSurface(Surface gms)

removes the submitted Surface from the aggregation

Specified by:

removeSurface in interface MultiSurface

Returns:

the removed Surface

removeSurfaceAt

public Surface removeSurfaceAt(int index)
                        throws GeometryException
