Class TraversalProcedure

java.lang.Object
  org.jcae.mesh.oemm.TraversalProcedure

public abstract class TraversalProcedure
extends java.lang.Object

Abstract class to implement OEMM traversal. Derived classes must define the action(org.jcae.mesh.oemm.OEMM, org.jcae.mesh.oemm.OEMM.Node, int, int) method.

See Also:

OEMM.walk(org.jcae.mesh.oemm.TraversalProcedure)

Field Summary

static int	ABORT Abort tree traversal immediately.
protected static int	LEAF Current node is a leaf
static int	OK Continue tree traversal.
protected static int	POSTORDER Current node is not a leaf and its children have already been processed.
protected static int	PREORDER Current node is not a leaf and its children have not been processed yet.
static int	SKIPCHILD Do not process children.

Constructor Summary

TraversalProcedure()

Method Summary

abstract int	action(OEMM o, OEMM.Node c, int octant, int visit) Abstract class which has to be overridden by subclasses.
void	finish(OEMM oemm) Method called after traversing the OEMM.
void	init(OEMM oemm) Method called before traversing the OEMM.

Method Detail

init

public void init(OEMM oemm)

Method called before traversing the OEMM.

finish

public void finish(OEMM oemm)

Method called after traversing the OEMM.

action

public abstract int action(OEMM o,
                           OEMM.Node c,
                           int octant,
                           int visit)

Abstract class which has to be overridden by subclasses.

Parameters:

o - OEMM structure

c - the current node of the OEMM structure

octant - the octant number in parent node

visit - this parameter is set to LEAF if the current node is a leaf, PREORDER if children have not yet been traversed, and POSTOREDER otherwise.

Returns:

ABORT exit from OEMM.walk(org.jcae.mesh.oemm.TraversalProcedure) immediately SKIPCHILD skip current cell (ie do not process its children) OK process normally
