Constructor Detail

• ASTMatcher()

Method Detail

• static List<TreeContext> find(ASTNode node, ASTNode pattern)

  Locates all nodes in the given AST which match the pattern AST. This operation can cost a lot, because it tries to match a sub-tree to every node of the AST.

  Parameters:

  node - an AST Node

  pattern - a pattern to be found somewhere in the AST

  Returns:

  a list of TreeContext, always not null.

• <T> T ifConstraint(T defaultValue, @DelegatesTo(value: MatchingConstraints, strategy: Closure.DELEGATE_FIRST) Closure<T> code)

• static boolean matches(ASTNode node, ASTNode pattern)

  Matches an AST with another AST (pattern). It will return true if the AST matches all the nodes from the pattern AST.

  Parameters:

  node - the AST we want to match with

  pattern - the pattern AST we want to match to

  Returns:

  true if this AST matches the pattern

  TODO: experimental! Annotates an AST node with matching contraints. This method should be called on an AST intended to be used as a pattern only. It will put node metadata on the AST node allowing customized behavior in pattern matching.

  Parameters:

  pattern - a pattern AST

  constraintsSpec - a closure specification of matching constraints

  Returns:

  the same pattern, annotated with constraints
