Eclipse JDT
Release 3.5

org.eclipse.jdt.core.dom
Class ASTMatcher

java.lang.Object
  extended by 
org.eclipse.jdt.core.dom.ASTMatcher

public class ASTMatcher
extends Object

Concrete superclass and default implementation of an AST subtree matcher.

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.

Constructor Detail

ASTMatcher

public ASTMatcher()
Creates a new AST matcher instance.

For backwards compatibility, the matcher ignores tag elements below doc comments by default. Use ASTMatcher(true) for a matcher that compares doc tags by default.


ASTMatcher

public ASTMatcher(boolean matchDocTags)
Creates a new AST matcher instance.

Parameters:
matchDocTags - true if doc comment tags are to be compared by default, and false otherwise
Since:
3.0

List list2)
Returns whether the given lists of AST nodes match pair wise according to ASTNode.subtreeMatch.

Note that this is a convenience method, useful for writing recursive subtree matchers.

Parameters:
list1 - the first list of AST nodes (element type: ASTNode)
list2 - the second list of AST nodes (element type: ASTNode)
Returns:
true if the lists have the same number of elements and match pair-wise according to ASTNode.subtreeMatch

Object node2)
Returns whether the given nodes match according to AST.subtreeMatch. Returns false if one or the other of the nodes are null. Returns true if both nodes are null.

Note that this is a convenience method, useful for writing recursive subtree matchers.

Parameters:
node1 - the first AST node, or null; must be an instance of ASTNode
node2 - the second AST node, or null; must be an instance of ASTNode
Returns:
true if the nodes match according to AST.subtreeMatch or both are null, and false otherwise

Javadoc node,
                     
Object other)
Returns whether the given node and the other object match.

Unlike other node types, the behavior of the default implementation is controlled by a constructor-supplied parameter ASTMatcher(boolean) which is false if not specified. When this parameter is true, the implementation tests whether the other object is also a Javadoc with structurally isomorphic child subtrees; the comment string (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.

Parameters:
node - the node
other - the other object, or null
Returns:
true if the subtree matches, or false if they do not match or the other object has a different node type or is null
