Direct Known Subclasses:

public class ASTDecoration

extends java.lang.Object

Provides an extensible way to add 'fields' to the ASTNode. Each ASTDecoration object essentially corresponds to an additional field in the ASTNode class. The value of this field for a particular ASTNode object is accessed and mutated via the instance methods get and set, respectively (see below). Each ASTDecoration object also has an associated String, which 'names' the corresponding field.
