A generic tree implementation with no payload.

typedef struct ANTLR3_BASE_TREE_struct ANTLR3_BASE_TREE
A generic tree implementation with no payload.

A generic tree implementation with no payload. You must subclass to actually have any user data. ANTLR v3 uses a list of children approach instead of the child-sibling approach in v2. A flat tree (a list) is an empty node whose children represent the list. An empty (as in it does not have payload itself), but non-null node is called 'nil'.
