Method Detail

getRectangularBounds

public Rectangle getRectangularBounds()

This method should return the Rectangular bounds of this non-terminal object.

getPolygonalBoundsArray

public Polygon[] getPolygonalBoundsArray()

This method should return the polygonal array bounds of this non-terminal object. This is a rough approximation of the constituents of the object.

getChildren

public Vector getChildren()

This method should return a vector containing the children of this object. Children are the Terminal or NonTerminal constituents of this object.
