Method Detail

findColumn

public static RainbowColumn findColumn(Tree tree)

Returns a RainbowColumn associated with the specified tree, creating it if needed.

Parameters:

tree - the tree

Returns:

a RainbowColumn associated with the specified tree, creating it if needed.

getColumn

public static RainbowColumn getColumn(Tree tree)

Returns a RainbowColumn associated with the specified tree or null if none exists.

Parameters:

tree - the tree

Returns:

a RainbowColumn associated with the specified tree or null if none exists.

preorder

public boolean preorder(int node)

Method called when the node is initially reached.

Specified by:

preorder in interface DepthFirst.Visitor

Parameters:

node - the reached node.

Returns:

true if the subtree should be traversed, false if it should be pruned from the traversal. In the latter case, the two other methods are not called for the node.

postorder

public void postorder(int node)

Method called when all the children of the node have been traversed.

Specified by:

postorder in interface DepthFirst.Visitor

Parameters:

node - the reached node.
