Private Attributes string  _name   the name of the label REF goto_list  _references   the list of referring gotos Detailed Description Label statement. This class represents label statements. The label has a name, and a child statement inherited from targetNode. In addition, it has a list that can hold references to all the goto statements that refer to it. This information is populated during initial parsing by the goto_label_walker. The NodeType is Label. See also: gotoNode goto_label_walker Definition at line 4859 of file ast.h. Constructor & Destructor Documentation labelNode::labelNode (  const char *    name, stmtNode *    stmt, const Coord    coord = Coord::Unknown )    Create a new label statement. The new label has the given name and child statement. The input string is copied and not deleted. Parameters: name  the name of the label (copied; not deleted) stmt  the child statement coord  the location of the construct in the source file. Definition at line 44 of file labelnode.cc. References Label. Referenced by clone(). labelNode::labelNode (  idNode *    ident, stmtNode *    stmt )    Create a label from an identfier. Definition at line 52 of file labelnode.cc. References Label. labelNode::labelNode (  idNode *    ident )    Create an empty label from an identifier. Definition at line 93 of file labelnode.cc. References Label. labelNode::~labelNode (    )  [virtual]   Destroy a labelNode. Warning: Do not use the destructors to delete AST nodes. Instead, rely on the node garbage collector. Definition at line 221 of file labelnode.cc. Member Function Documentation annote_list& Node::annotations (    )  [inline, inherited]   Get the annotations list. This method returns a modifiable reference to the list of annotations on the node. Users can add new annotations, search for annotations, or remove annotations. Users are responsible for ensuring that every element of the annotation list points to a valid annotation. In particular, no element should be NULL.

This method differs from the Node::type() method in two respects. First, it follows some of the simple type inferences. For example, calling it on an idNode will return the type of its declaration. Second, the boolean argument indicates whether or not to follow typedef links. Parameters: TdefIndir  pass true to follow typedefs to their definitions.

Referenced by Node::datatype(), and Node::datatype_superior(). Node * labelNode::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. Implements Node. Definition at line 185 of file labelnode.cc. References Changer::at_label(), Changer::Both, blockNode::change(), Changer::order(), Changer::Order, Changer::Postorder, Changer::Preorder, and targetNode::stmt(). virtual Node* labelNode::clone (    )  const [inline, virtual]   Clone the input node. This is not a "deep" clone, so be careful. For a deep clone, use the ref_clone_changer class. Returns: a shallow copy of the node (no subtrees are copied). Implements Node.

This location should indicate the position in the source text that this Node represents, or Coord::Unknown if it does not represent any node in the source text. It is not common to set the source location of a node. Currently, only the compiler error messages actually make use of it. Parameters: coord  the new location. Definition at line 245 of file ast.h. Coord Node::coord (    )  const [inline, inherited]   Get the source location. The Coord class holds a location in the input source (file, line, position). During parsing, each AST node created records the position of the source text that it represents. However, subsequent phases may create or change nodes, so no guarantee is given about how the source location corresponds to the original source text. Returns: the Coord structure indicating where the node came from in the source file. Definition at line 232 of file ast.h.

Each subclass overrides this method to define it's semantics for dataflow analysis.
