Detailed Description

template<>
class TypedExpression< bool >

An expression that evaluates to a boolean value.

Expressions returning a bool should derive from this class and implement the evalImpl(EvalAs<bool>) method.

Public Member Functions
	TypedExpression ()
virtual bool	evalImpl (EvalAs< bool >, const EvalContext &ctxt)=0 throw ( EvalException )
