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)

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

Parameters

◆ setListener()

def OpenRTM_aist.PublisherPeriodic.PublisherPeriodic.setListener	(	self,

Set the listener.

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

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

int PublisherPeriodic::svc(void)

Definition at line 619 of file PublisherPeriodic.py.

◆ write()

def OpenRTM_aist.PublisherPeriodic.PublisherPeriodic.write	(	self,
		data,
		sec,
		usec
	)

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.
