Method Detail

traversalOperation

public boolean traversalOperation(Node node)

Description copied from interface: TraversalCallback

This method is called for each Node in the traversed Group. It implements the operation to be done for the Nodes.

Specified by:

traversalOperation in interface TraversalCallback

Parameters:

node - the current Node in the traversal

Returns:

if false, the traversal is stopped after this node

traversalCheckGroup

public boolean traversalCheckGroup(GroupNode group)

Description copied from interface: TraversalCallback

This method is called for each Group in the traversal. It must return true to be further traversed (and its children)

Specified by:

traversalCheckGroup in interface TraversalCallback

Parameters:

group - the Group to be checked

Returns:

if false the traversal is not stopped, but the children are not further traversed

getPolygonCount

public static int getPolygonCount(GroupNode group)

Counts the number of vertices in the traversed Group.

Parameters:

group - the group to search

Returns:

the number of vertices
