Member Function Documentation

int TAO_Unary_Constraint::accept (  TAO_Constraint_Visitor *  visitor  )  [virtual]
 

Implementing the pattern of double dispatching, each subclass of TAO_Constraint will call back on an InterpreterVisitor the method to handle a node of its ExpressionType.

Implements TAO_Constraint.
