deactivation

This function deactivates the publisher. By calling this function, this publisher stops the thread that pushes data to InPort. If precondition such as initialization process and so on is not met, the error code PRECONDITION_NOT_MET is returned.

PublisherBase::ReturnCode RTC::PublisherPeriodic::init ( coil::Properties & prop ) [virtual]

Initialization.

initialization

This function have to be called before using this class object. Properties object that includes certain configuration information should be given as an argument. At least, a numerical value of unit of Hz with the key of "dataport.publisher.push_rate" has to be set to the Properties object of argument. The value is the invocation cycle of data sending process. In case of 5 ms period or 200 Hz, the value should be set as 200.0. False will be returned, if there is no value with the key of "dataport.publisher.push_rate".

The following options are available.

publisher.thread_type: Thread type (string, default: default)
publisher.push_rate: Publisher sending period (numberical)
publisher.push_policy: Push policy (all, fifo, skip, new)
publisher.skip_count: The number of skip count in the "skip" policy
measurement.exec_time: Task execution time measurement (enable/disable)
measurement.exec_count: Task execution time measurement count (numerical, number of times)
measurement.period_time: Task period time measurement (enable/disable)
measurement.period_count: Task period time measurement count (number, count)

Parameters:

property Property objects that includes the control information of this Publisher

Returns:: ReturnCode PORT_OK normal return INVALID_ARGS Properties with invalid values.

PublisherBase::ReturnCode RTC::PublisherPeriodic::setBuffer ( CdrBufferBase * buffer ) [virtual]

Setting buffer pointer.

This operation sets a buffer that is associated with this object. If the buffer object is NULL, INVALID_ARGS will be returned.

Parameters:

buffer A pointer to a CDR buffer object.

Returns:: ReturnCode PORT_OK normal return INVALID_ARGS given argument has invalid value

Definition at line 129 of file PublisherPeriodic.cpp.

PublisherBase::ReturnCode RTC::PublisherPeriodic::setConsumer ( InPortConsumer * consumer ) [virtual]

Store InPort consumer.

This operation sets a consumer that is associated with this object. If the consumer object is NULL, INVALID_ARGS will be returned.

Parameters:

consumer A pointer to a consumer object.

Returns:: ReturnCode PORT_OK normal return INVALID_ARGS given argument has invalid value

Implements RTC::PublisherBase.

Definition at line 109 of file PublisherPeriodic.cpp.

PublisherBase::ReturnCode RTC::PublisherPeriodic::setListener	(	ConnectorInfo &	info,
		ConnectorListeners *	listeners
	)		`[virtual]`

Set the listener.

Setting buffer pointer.

This function sets ConnectorListeners listener object to the Publisher. By setting ConnectorListeners containing various listeners objects, these listeners are called at the time of reading and writing of a buffer, and transmission of data etc. Since the ownership of the ConnectorListeners object is owned by Port or RTObject, the Publisher never deletes the ConnectorListeners object. If the given ConnectorListeners' pointer is NULL, this function returns INVALID_ARGS.

Parameters:

info	ConnectorInfo that is localized object of ConnectorProfile
listeners	ConnectorListeners that holds various listeners

Returns:: PORT_OK Normal return INVALID_ARGS Invalid arguments

Implements RTC::PublisherBase.

Definition at line 150 of file PublisherPeriodic.cpp.

void RTC::PublisherPeriodic::setPushPolicy ( const coil::Properties & prop ) [protected]

Setting PushPolicy.

Definition at line 408 of file PublisherPeriodic.cpp.

int RTC::PublisherPeriodic::svc ( void ) [virtual]

Thread execution function.

A task execution function to be executed by coil::PeriodicTask.

Definition at line 253 of file PublisherPeriodic.cpp.

PublisherBase::ReturnCode RTC::PublisherPeriodic::write	(	const cdrMemoryStream &	data,
		unsigned long	sec,
		unsigned long	usec
	)		`[virtual]`

Write data.

This function writes data into the buffer associated with this Publisher. If a Publisher object calls this function, without initializing correctly such as a consumer, a buffer, listeners, etc., error code PRECONDITION_NOT_MET will be returned and no operation of the writing to a buffer etc. will be performed.

Since writing into the buffer and sending data to InPort are performed asynchronously, occasionally this function returns return-codes such as CONNECTION_LOST and BUFFER_FULL that indicate the result of sending data to InPort. In this case, writing data into buffer will not be performed.

When publisher writes data to the buffer, if the buffer is filled, returns error, is returned with timeout and returns precondition error, error codes BUFFER_FULL, BUFFER_ERROR, BUFFER_TIMEOUT and PRECONDITION_NOT_MET will be returned respectively.

In other cases, PROT_ERROR will be returned.

Parameters:

data	Data to be wrote to the buffer
sec	Timeout time in unit seconds
nsec	Timeout time in unit nano-seconds

Returns:: PORT_OK Normal return PRECONDITION_NO_MET Precondition does not met. A consumer, a buffer, listenes are not set properly. CONNECTION_LOST detected that the connection has been lost BUFFER_FULL The buffer is full status. BUFFER_ERROR Some kind of error occurred in the buffer. NOT_SUPPORTED Some kind of operation that is not supported has been performed. TIMEOUT Timeout occurred when writing to the buffer.
