Detailed Description

Jump target.

This class provides a base class for all statements that serve as targets for jumps. This includes the regular goto labels, as well as the switch cases and default. Note that in C, all labels refer to a statement. Syntactically, the labelled statement in the child of the label. For example, "case 5: x = 10; " results in a labelNode that has an exprstmtNode as it's child.

The NodeType is determined by the subclass (either Label, Case, or Default).

Constructor & Destructor Documentation

targetNode::targetNode (  NodeType    typ, stmtNode *    stmt, const Coord    coord )

Create a new target node. The new node has the given type and target statement. Parameters: typ  the kind of target node (either Label, Case, or Default) stmt  the target statement

targetNode::~targetNode (    )  [virtual]

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