metastmtNode::metastmtNode (  idNode *    id )  [inline]

Member Function Documentation

void metastmtNode::add_meta_stmt (  char *    name )  [static]

Node * metastmtNode::change (  Changer &    the_changer, bool    redispatch = false )  [virtual]

Dispatch a Changer. This abstract method works much the walker, but allows the tree to be changed. Parameters: the_changer  the specific Changer object to use. redispatch  pass true to revisit parts of the tree that have changed. Reimplemented from Node.

void metastmtNode::clear (    )  [static]

virtual Node* metastmtNode::clone (    )  const [inline, virtual]

Clone the input node. This is not a "deep" clone, so be careful. For a deep clone, use the clone_changer class. Returns: a shallow copy of the node (no subtrees are copied). Reimplemented from Node.

void metastmtNode::dataflow (  FlowVal *    v, FlowProblem &    fp )  [virtual]

Run the dataflow analyzer. Each subclass overrides this method to define it's semantics for dataflow analysis. It alters the input flow value to reflect the effect of the node within the given flow problem, calling dataflow() on it's subtrees as necessary. See the dataflow analysis documentation for more information. Parameters: v  the flow value to pass through the node. fp  the flow problem (specifying the transfer functions). Reimplemented from Node.

bool metastmtNode::is_meta_stmt (  char *    name )  [static]

void metastmtNode::output_stmt (  output_context &    ct, Node *    par )  [virtual]

Output a statement. Reimplemented from stmtNode.

void metastmtNode::visit (  Visitor *    the_visitor )  [virtual]

Dispatch a Visitor. This abstract method is the entry point for the visitor design pattern. Each node subclass defines a visit() method that calls the appropriate at_ method in the visitor. For more information see the Visitor documentation. Parameters: the_visitor  the specific Visitor object to use. Reimplemented from Node.

void metastmtNode::walk (  Walker &    the_walker )  [virtual]

Dispatch a Walker. This abstract method works much like the visitor, but instead walks the entire underlying subtree calling the appropriate at_ method at each node. For more information see the Walker documentation. Parameters: the_walker  the specific Walker object to use. Reimplemented from Node.
