Member Function Documentation

virtual void sosscli::ExpressionComparand::accept ( QueryExpression::Visitor &  v) const

pure virtual

Standard QueryExpression::Visitor accept(QueryExpression::Visitor &) method allowing visitors to visit ExpressionComparand subclasses as well as QueryExpression subclasses.

ExpressionComparand subclasses each implement this method as

void accept(Visitor &v) 
{
 v.visit(*this);
} 

Thus, the appropriate overload of QueryExpression::Vistor::visit is called, passing the ExpressionComparand node to the visitor.

Parameters

v	The QueryExpression::Visitor visitor instance.

Implemented in sosscli::ReferenceComparand, and sosscli::ValueComparand.
