Constructor & Destructor Documentation

textNode::textNode (  const char *    text, bool    start_new_line, const Coord    coord = Coord::Unknown )

textNode::~textNode (    )  [virtual]

Destroy a textNode. Warning: Do not use the destructors to delete AST nodes. Instead, rely on the node garbage collector.

Member Function Documentation

Node * textNode::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.

virtual Node* textNode::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.

virtual void textNode::dataflow (  FlowVal *    v, FlowProblem &    fp )  [inline, 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.

void textNode::output (  output_context &    ct, Node *    parent )  [virtual]

Generate C code. Each subclass overrides this method to define how to produce the output C code. To use this method, pass an output_context and a null parent. Parameters: ct  the output context which describes the formatting. par  the parent node (or null, if at the top of a subtree). Reimplemented from Node.

void textNode::start_new_line (  bool    start_new_line )  [inline]

bool textNode::start_new_line (    )  const [inline]

void textNode::text (  string    text )  [inline]

string& textNode::text (    )  [inline]

void textNode::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 textNode::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.
