Method Detail

traverseChild

public void traverseChild(Glyph g)

Description copied from class: Traversal

Traverses to the specified Glyph.

Specified by:

traverseChild in class Traversal

Parameters:

g - the Glyph to traverse to.

hit

public void hit()

Description copied from class: Traversal

Mark current glyph as a hit in a pick traversal of the scenegraph. NOTE: This method is not implemented in this class, it needs to be implemented by a pick traversal subclass.

Overrides:

hit in class Traversal

isOverview

public boolean isOverview()

getHitList

public java.util.List getHitList()

getLastHit

public org.w3c.dom.Element getLastHit()

getProjectionPlane

public double[] getProjectionPlane()

resetShapes

public void resetShapes()

addShape

public void addShape(FShape shape,
                     int order)

getShapes

public java.util.Iterator getShapes()
