Detailed Description

Selection statement.

This class provides a base class for all the control-flow selection statements. This includes the "if" statement, with and without an "else" and the "switch" statement. All three statements have a selection expression, and at least one child statement. For the if-else statements, we add another child statement to represent the false branch.

The NodeType is determined by the subclass (If or Switch).

Constructor & Destructor Documentation

selectionNode::selectionNode (  NodeType    typ, exprNode *    expr, stmtNode *    stmt, const Coord    coord )

Create a new selection statement. The new selection statement has the given type, selection expression and child statement. This constructor is only called by the selectionNode subclass. Parameters: typ  the kind of selection statement expr  the selection expression stmt  the child statement coord  the location of the construct in the source file.

selectionNode::~selectionNode (    )  [virtual]

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