public class ASTMatcher extends Object
For example, to compute whether two ASTs subtrees are structurally
isomorphic, use n1.subtreeMatch(new ASTMatcher(), n2) where
n1 and n2 are the AST root nodes of the subtrees.
For each different concrete AST node type T there is a
public boolean match(T node, Object other) method
that matches the given node against another object (typically another
AST node, although this is not essential). The default implementations
provided by this class tests whether the other object is a node of the
same type with structurally isomorphic child subtrees. For nodes with
list-valued properties, the child nodes within the list are compared in
order. For nodes with multiple properties, the child nodes are compared
in the order that most closely corresponds to the lexical reading order
of the source program. For instance, for a type declaration node, the
child ordering is: name, superclass, superinterfaces, and body
declarations.
Subclasses may override (extend or reimplement) some or all of the
match methods in order to define more specialized subtree
matchers.

When this parameter is true, the implementation
tests whether the other object is also a Javadoc

(Javadoc.getComment()) is ignored.
Conversely, when the parameter is false, the
implementation tests whether the other object is also a
Javadoc with exactly the same comment string;
the tag elements (Javadoc.tags are
ignored. Subclasses may reimplement.
