Class CNode

public class CNode
extends java.lang.Object

CNode is a standard tree data structure. The children of a node are stored as a linked list, with the end of the list indicated by next==NULL. The start and end fields of a node indicate the span of the constituent, with the first word indexed by 0. Leaves are defined by the condition child==NULL. There are three basic functions to work with the constituent structure: CNode linkage_constituent_tree(); String linkage_print_constituent_tree(int mode); The function linkage_constituent_tree returns a pointer to a tree; In the function linkage_print_constituent_tree, the parameter mode=1 specifies that the tree is displayed using the nested Lisp format, and mode=2 specifies that a flat tree is displayed using brackets. When mode=0, no constituent structure is generated and a null string is returned. The string returned by a call to linkage_print_constituent_tree is automatically freed by garbage collection.
