Detailed Description

template<bool inverted>
class BoolExpression< inverted >

An Expression consisting of a single boolean (Bool).

Definition at line 32 of file Bool.h.

Public Types
typedef BoolExpression<!inverted >	inverted_type
	The type of the inverted expression.
typedef bool	evaluation_type
	The return type of evaluate_impl.
Public Member Functions
	BoolExpression (Bool &b)
	Copy constructor.
BoolExpression<!inverted >	operator! (void) const
	Inversion operator. Returns an inverted expression.
ExpressionEventServer &	create_event_server (void)
	Create and return an event server that is watching this expression.
bool	evaluate_impl (void) const
	Evaluate this expression.
void	sub_event_server_impl (ExpressionEventServer *)
	Implementation of sub_event_server(). Remove event server event_server from the notification list.
virtual void	add_event_server (boost::shared_ptr< ExpressionEventServer > const &event_server)
	Add event server event_server to notification list.
virtual bool	evaluate (void)
	Implementation of pure virtual function ExpressionInterface::evaluate.
virtual void	sub_event_server (ExpressionEventServer *event_server)
	Implementation of pure virtual function ExpressionInterface::sub_event_server.
virtual void	print_on (std::ostream &os) const
	For debugging purposes. Write the contents of this object to os.
Private Attributes
Bool &	M_b
	The underlying Bool.
