    • Method Detail

      • acceptAST

        public void acceptAST​(ICompilationUnit source,
                              CompilationUnit ast)
        Accepts an AST corresponding to the compilation unit. That is, ast is an AST for source.

        The default implementation of this method does nothing. Clients should override to process the resulting AST.

        Parameters:
        source - the compilation unit the ast is coming from
        ast - the requested abtract syntax tree
      • acceptBinding

        public void acceptBinding​(String bindingKey,
                                  IBinding binding)
        Accepts a binding corresponding to the binding key. That is, binding is the binding for bindingKey; binding is null if the key cannot be resolved.

        The default implementation of this method does nothing. Clients should override to process the resulting binding.

        Parameters:
        bindingKey - the key of the requested binding
        binding - the requested binding, or null if none
      • createBindings

        public final IBinding[] createBindings​(String[] bindingKeys)
        Resolves bindings for the given binding keys. The given binding keys must have been obtained earlier using IBinding.getKey().

        If a binding key cannot be resolved, null is put in the resulting array. Bindings can only be resolved in the dynamic scope of a ASTParser.createASTs, and only if ASTParser.resolveBindings(true) was specified.

        Caveat: During an acceptAST callback, there are implementation limitations concerning the look up of binding keys representing local elements. In some cases, the binding is unavailable, and null will be returned. This is only an issue during an acceptAST callback, and only when the binding key represents a local element (e.g., local variable, local class, method declared in anonymous class). There is no such limitation outside of acceptAST callbacks, or for top-level types and their members even within acceptAST callbacks.

        Parameters:
        bindingKeys - the binding keys to look up
        Returns:
        a list of bindings paralleling the bindingKeys parameter, with null entries for keys that could not be resolved
