Interface PTBTreeNode

All Superinterfaces:

javax.swing.tree.MutableTreeNode, javax.swing.tree.TreeNode

All Known Implementing Classes:

PTBTreeNodeImpl

public interface PTBTreeNode

extends javax.swing.tree.MutableTreeNode

A node in the PTB. The label of the node is PTBLabel. This is similar to various other interfaces to the PTB, but Java™'s treatment of method namespaces results in incompatibilities between the Swing interfaces and/or DOM and other treebank interfaces. The intended uses for this interface are mainly querying and display.

The setter methods here are for internal use only with the exception of setLabel, and ptbAppendChild, and implementations may impose their own semantics. To mutate the tree, use the methods provided by the MutableTreeNode superinterface. Also note that the label and userObject are separate.

To avoid name clashes, some commonly used methods are prefixed with ptb.

Version 2 Changes: Two methods: "ptbSetAttribute" and "ptbGetAttribute" have been removed for performance reasons. There is no way to add custom attributes now. PTBLabel has a corresponding change.

0.1
