public void copyFrom(RBNode arg)

Doc from sun.jvm.hotspot.utilities.RBNode.copyFrom.

Must copy all user-defined fields from the given node. For example, the base implementation copies the "data" field. However, it does not (and must not) copy the link fields (parent, left child, right child). It also does not need to copy any computed information for the node, as the node will be updated when necessary. Subclasses must be careful to call the superclass implementation.

public String toString()

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

updateback to summary
public boolean update()

Overrides sun.jvm.hotspot.utilities.RBNode.update.

Doc from sun.jvm.hotspot.utilities.RBNode.update.

This is called by the base RBTree's insertion and deletion methods when necessary. Subclasses can use this to update any computed information based on the information in their left or right children. For multi-node updates it is guaranteed that this method will be called in the correct order. This should return true if an update actually occurred, false if not.
