Class ASTMatcher
java.lang.Object
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.

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
-

safeSubtreeListMatch
public final boolean safeSubtreeListMatch(
List list1,
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)
-

true if the lists have the same number of elements
and match pair-wise according to ASTNode.subtreeMatch
-

-
ASTNode.subtreeMatch(ASTMatcher matcher, Object other)
safeSubtreeMatch
public final boolean safeSubtreeMatch(
Object node1,
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.

node1 - the first AST node, or null; must be an
instance of ASTNode
-
node2 - the second AST node, or null; must be an

public boolean match(
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.

match
public boolean match(
VariableDeclarationExpression node,
Object other)
- Returns whether the given node and the other object match.
The default implementation provided by this class tests whether the
other object is a node of the same type with structurally isomorphic
child subtrees. Subclasses may override this method as needed.
-
-
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
match
public boolean match(
VariableDeclarationFragment node,
Object other)
- Returns whether the given node and the other object match.
The default implementation provided by this class tests whether the
other object is a node of the same type with structurally isomorphic
child subtrees. Subclasses may override this method as needed.
Note that extra array dimensions are compared since they are an
important part of the type of the variable.

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
match
public boolean match(
VariableDeclarationStatement node,
Object other)
- Returns whether the given node and the other object match.
The default implementation provided by this class tests whether the
other object is a node of the same type with structurally isomorphic
child subtrees. Subclasses may override this method as needed.
-
-
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
match
public boolean match(
WhileStatement node,
Object other)
- Returns whether the given node and the other object match.
The default implementation provided by this class tests whether the
other object is a node of the same type with structurally isomorphic
child subtrees. Subclasses may override this method as needed.
-
-
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
match
public boolean match(
WildcardType node,
Object other)
- Returns whether the given node and the other object match.
The default implementation provided by this class tests whether the
other object is a node of the same type with structurally isomorphic
child subtrees. Subclasses may override this method as needed.
-
-
Parameters:
-
node - the node -
other - the other object, or null
