Detailed Description

Loop node.

This class provides a base class for all the kinds of loop statements.

The NodeType is determined by the subclass (While, Do, or For)

Constructor & Destructor Documentation

loopNode::loopNode (  NodeType    typ, exprNode *    cond, stmtNode *    body, const Coord    coord )

Create a new loop. The new loop has the given type, condition expression and body. This constructor is only called by the subclasses (whileNode, doNode, and forNode). Parameters: typ  the type of loop (While, Do, or For) cond  the loop condition body  the loop body coord  the location of the construct in the source file.

loopNode::loopNode (  NodeType    typ, const Coord    coord )

Create an empty loop. The new loop has no condition expression or body Parameters: typ  the type of loop (While, Do, or For) coord  the location of the construct in the source file.

loopNode::~loopNode (    )  [virtual]

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

Member Data Documentation

FlowVal* loopNode::_at_loop_head [private]

loop head dataflow analysis value. This field is used by the dataflow analysis framework to hold the flow value at the head of the loop.

FlowVal* loopNode::_at_loop_tail [private]

loop tail dataflow analysis value. This field is used by the dataflow analysis framework to hold the flow value at the end (tail) of the loop.

TREE blockNode* loopNode::_body [private]

the loop body.

TREE exprNode* loopNode::_cond [private]

the loop condition expression.
