Method Detail

getEndpoint

public TGT_ConnectionPoint getEndpoint(int which)
                                throws java.util.NoSuchElementException

Returns one of the endpoints for this TGT_ConnectionPoint.

Parameters:

which - 0 or 1, for the "left" or "right" endpoint.

Returns:

the TGT_ConnectionPoint representing the requested endpoint of this connector.

Throws:

java.util.NoSuchElementException - when "which" is a value other than 0 or 1.

setEndpoint

public void setEndpoint(TGT_ConnectionPoint ep,
                        int which)
                 throws java.util.NoSuchElementException

Change one of the endpoints of this connector.

Parameters:

ep - the new endpoint

which - 0 for the "left" endpoint, 1 for the "right" endpoint.

Throws:

java.util.NoSuchElementException - when "which" is a value other than 0 or 1.

draw

public void draw(java.awt.Graphics g,
                 java.awt.image.ImageObserver o)

Description copied from class: TGT_DrawableSprite

Draw this sprite's appearance. This method is implemented by each derived class.

Specified by:

draw in interface TGT_AbstractSprite

Specified by:

draw in class TGT_DrawableSprite

Parameters:

g - The Graphics object to use for drawing.

o - The ImageObserver that this sprite belongs to.

isHorizontal

public boolean isHorizontal()

Is this connector horizontal?

Returns:

true if the connector is exactly horizontal, false otherwise.

isVertical

public boolean isVertical()

Is this connector vertical?

Returns:

true if the connector is exactly vertical, false otherwise.

computeDecoratorOrientation

protected int computeDecoratorOrientation(int endptidx)
