Constructor & Destructor Documentation doNode::doNode (  stmtNode *    body, exprNode *    cond, const Coord    coord = Coord::Unknown, const Coord    while_coord = Coord::Unknown )    Create a new do-while loop. The new do-while loop has the given condition expression and body. Parameters: cond  the loop condition body  the loop body coord  the location of the "do" keyword in the source file. coord  the location of the "while" keyword in the source file. Definition at line 44 of file donode.cc. References Do. Referenced by clone(). doNode::~doNode (    )  [virtual]   Destroy a doNode. Warning: Do not use the destructors to delete AST nodes. Instead, rely on the node garbage collector. Definition at line 243 of file donode.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. See also: Annote class Definition at line 276 of file ast.h.

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.

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.
