Defines an event condition

Inheritance:

Public Methods

	Condition () Default constructor
virtual	~Condition () Destructor
virtual Condition*	Copy () const Copy the event
virtual bool	Evaluate (const Argument& arg, bool& val) const Evaluate
bool	operator() (const Argument& arg, bool& val) const () operator
bool	operator() (const Event& event, bool& val) const () operator
static const Condition&	True () True
static const Condition&	False () False

Protected Methods

	Condition (const Condition&) Copy constructor
Condition&	operator= (const Condition&) Assignment operator

Documentation

Event condition. Event conditions can be evaluated on one, two (coincidence) or three (triple-coincidence) events.

Condition()

Creates an event condition which is always false.

virtual ~Condition()

Destructs the event condition.

virtual Condition* Copy() const = 0

Returns a copy of the event condition. This method must be overriden by all descendents.

Returns:

event copy

virtual bool Evaluate(const Argument& arg, bool& val) const = 0

Evaluate the condition. This function must be overriden by descendents.

Parameters:

- arg Event argument list
val - Condition value (return)

Returns:

True if condition could be evaluated

bool operator() (const Argument& arg, bool& val) const

Condition call operator. Returns the same as evaluate (should not be overriden).

Parameters:

event - Event upon condition is evaluated
val - Condition value (return)

Returns:

True if condition could be evaluated

bool operator() (const Event& event, bool& val) const

Condition call operator. Evaluates a condition on a single event (should not be overriden).

Parameters:

- arg Event argument list
val - Value (return)

Returns:

True if function could be evaluated

static const Condition& True()

Returns a condition which yields always true.

static const Condition& False()

A condition which yields always false.

Condition(const Condition&)

Copy constructor. This is almost never intended, so just disable it from the outside.

Condition& operator= (const Condition&)

Assignment operator. This is almost never intended, so just disable it from the outside.
