Detailed Description

A conditional that evaluates true after a certain time has passed. The behaviour can be inverted upon construction.

Constructor & Destructor Documentation

RTT::ConditionDuration::ConditionDuration	(	nsecs	t,
		bool	invert = `false`
	)

Create a condition that changes after t nano seconds

Parameters:

t	the period of time starting from reset()
invert	If false (default) then the condition will raise to true after t. If true then the condition will fall to false after t.

ConditionInterface * RTT::ConditionDuration::clone ( ) const [virtual]

Implements RTT::scripting::ConditionInterface.

bool RTT::ConditionDuration::evaluate ( ) [virtual]

Evaluate the Condition and return the outcome.

Returns:: true if the condition is satisfied, false otherwise.

Implements RTT::scripting::ConditionInterface.

Definition at line 55 of file ConditionDuration.cpp.

void RTT::ConditionDuration::reset ( void ) [virtual]

Some conditions need to be reset at some points. E.g. a scripting::ConditionDuration counts the time since the first time a Command was executed, and if this time exceeds a certain preset time, returns true. Therefore, it needs to be reset, i.e. it needs to start counting, when the command is first executed.. scripting::ConditionOnce has a similar need. This function is called at such times.

Reimplemented from RTT::scripting::ConditionInterface.
