Method Summary

void	addPoint(GM_Point gmp) adds a GM_Point to the aggregation
GM_Point[]	getAllPoints() returns all GM_Points as array
GM_Point	getPointAt(int index) returns the GM_Point at the submitted index.
void	insertPointAt(GM_Point gmp, int index) inserts a GM_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.
GM_Point	removePoint(GM_Point gmp) removes the submitted GM_Point from the aggregation
GM_Point	removePointAt(int index) removes the GM_Point at the submitted index from the aggregation.
void	setPointAt(GM_Point gmp, int index) sets the submitted GM_Point at the submitted index. the element at the position index will be removed. if index is larger then getSize() - 1 or smaller then 0 or gmp equals null an exception will be thrown.

Method Detail

addPoint

public void addPoint(GM_Point gmp)

adds a GM_Point to the aggregation

insertPointAt

public void insertPointAt(GM_Point gmp,
                          int index)
                   throws GM_Exception

inserts a GM_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.

Parameters:

gmp - GM_Point to insert.

index - position where to insert the new GM_Point

Throws:

GM_Exception

setPointAt

public void setPointAt(GM_Point gmp,
                       int index)
                throws GM_Exception

sets the submitted GM_Point at the submitted index. the element at the position index will be removed. if index is larger then getSize() - 1 or smaller then 0 or gmp equals null an exception will be thrown.

Parameters:

gmp - GM_Point to set.

index - position where to set the new GM_Point

Throws:

GM_Exception

removePoint

public GM_Point removePoint(GM_Point gmp)

removes the submitted GM_Point from the aggregation

Returns:

the removed GM_Point

removePointAt

public GM_Point removePointAt(int index)
                       throws GM_Exception

removes the GM_Point at the submitted index from the aggregation. if index is larger then getSize() - 1 or smaller then 0 an exception will be thrown.

Returns:

the removed GM_Point

Throws:

GM_Exception

getPointAt

public GM_Point getPointAt(int index)

returns the GM_Point at the submitted index.

getAllPoints

public GM_Point[] getAllPoints()

returns all GM_Points as array
