Detailed Description

<<extension>> <<value-type>> Specifies the dds::core::cond::WaitSet behavior for multiple trigger events

In simple use, a dds::core::cond::WaitSet returns when a single trigger event occurs on one of its attached dds::core::cond::Condition (s), or when the timeout maximum wait duration specified in the dds::core::cond::WaitSet::wait call expires.

The rti::core::cond::WaitSetProperty allows configuration of the waiting behavior of a dds::core::cond::WaitSet. If no conditions are true at the time of the call to wait, then the max_event_count parameter may be used to configure the WaitSet to wait for max_event_count trigger events to occur before returning, or to wait for up to max_event_delay time from the occurrence of the first trigger event before returning.

The timeout maximum wait duration specified in the dds::core::cond::WaitSet::wait call continues to apply.

Constructor & Destructor Documentation

rti::core::cond::WaitSetProperty::WaitSetProperty

(

)

Creates the default WaitSetProperty.

rti::core::cond::WaitSetProperty::WaitSetProperty	(	int32_t	the_max_event_count,
		const dds::core::Duration &	the_max_event_delay
	)

Creates a WaitSetProperty with the given parameters.

Member Function Documentation

int32_t rti::core::cond::WaitSetProperty::max_event_count

(

)

const

Gets the max_event_count.

See Also

max_event_count(int32_t)

WaitSetProperty& rti::core::cond::WaitSetProperty::max_event_count

(

int32_t

value

)

Sets the maximum number of trigger events to cause a WaitSet to wake up.

The dds::core::cond::WaitSet will wait until up to max_event_count trigger events have occurred before returning. The dds::core::cond::WaitSet may return earlier if either the timeout duration has expired, or max_event_delay has elapsed since the occurrence of the first trigger event. max_event_count may be used to "collect" multiple trigger events for processing at the same time.

dds::core::Duration rti::core::cond::WaitSetProperty::max_event_delay

(

)

const

Gets the max_event_delay.

See Also

max_event_delay(const dds::core::Duration&)

WaitSetProperty& rti::core::cond::WaitSetProperty::max_event_delay

(

const dds::core::Duration &

value

)

Sets the maximum delay from occurrence of first trigger event to cause a WaitSet to wake up.

The dds::core::cond::WaitSet will return no later than max_event_delay after the first trigger event. max_event_delay may be used to establish a maximum latency for events reported by the dds::core::cond::WaitSet.

Note that dds::core::TimeoutError is not returned if max_event_delay is exceeded. dds::core::TimeoutError is returned only if the timeout duration expires before any trigger events occur.
