Private Attributes TREE expr_list  _exprs   The comma-separated expressions. Detailed Description Comma-separated expressions. This class represents a comma-separated list of expressions. Rather than represent the comma operator as a binary expression, we gather together a series of commas and put them in a single node. The NodeType is Comma. Definition at line 3922 of file ast.h. Constructor & Destructor Documentation commaNode::commaNode (  expr_list *    exprs, const Coord    coord = Coord::Unknown )    Create a new comma expression. The new comma node has the given list of expressions. The elements are removed from the list and the list is destroyed. Parameters: exprs  the list of expressions coord  the location of the construct in the source file. Definition at line 44 of file commanode.cc. References _exprs, and Comma. Referenced by clone(). commaNode::commaNode (  const Coord    coord = Coord::Unknown )    Create an empty comma expression. The new comma node has no expressions initially. They can be added by modifying the _exprs list. Parameters: coord  the location of the construct in the source file. Definition at line 54 of file commanode.cc. References Comma. commaNode::~commaNode (    )  [virtual]   Destroy a commaNode. Warning: Do not use the destructors to delete AST nodes. Instead, rely on the node garbage collector. Definition at line 220 of file commanode.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. References annote_list. typeNode * commaNode::base_type (  bool    TdefIndir )  const [virtual]   Return the base data type of a node. 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. Reimplemented from exprNode. Definition at line 63 of file commanode.cc. References expr_list, and exprs(). Node * commaNode::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 182 of file commanode.cc. References Changer::at_comma(), Changer::Both, Node::change(), change_list(), exprs(), Changer::order(), Changer::Order, Changer::Postorder, Changer::Preorder, and exprNode::type(). virtual Node* commaNode::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. Definition at line 3996 of file ast.h. References commaNode(). void Node::coord (  const Coord    coord )  [inline, inherited]   Set the source location. 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. 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). Implements Node.
