Detailed Description

PublisherNew class.

Send new data at timing of when it is stored into the buffer. This class is used when operating Consumer that waits for the data send timing in different thread from one of the send side. Publisher's driven is blocked until the data send timing reaches, if the send timing notification is received, the Consumer's send processing will be invoked immediately.

A Publisher can be activated/deactivated synchronized with the data port. The active state and the non-active state are made transition by the "activate()" and the "deactivate()" functions respectively. This function confirms if the publisher is in active state.

Returns:
Result of state confirmation (Active state:true, Inactive state:false)

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:
bufferA pointer to a CDR buffer object.
Returns:
ReturnCode PORT_OK normal return INVALID_ARGS given argument has invalid value

Definition at line 122 of file PublisherNew.cpp.

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:
consumerA pointer to a consumer object.
Returns:
ReturnCode PORT_OK normal return INVALID_ARGS given argument has invalid value

Implements RTC::PublisherBase.

Definition at line 102 of file PublisherNew.cpp.

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:
infoConnectorInfo that is localized object of ConnectorProfile
listenersConnectorListeners that holds various listeners
Returns:
PORT_OK Normal return INVALID_ARGS Invalid arguments

Implements RTC::PublisherBase.

Definition at line 143 of file PublisherNew.cpp.

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

Setting PushPolicy.

Definition at line 277 of file PublisherNew.cpp.

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

Thread execution function.

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

Definition at line 245 of file PublisherNew.cpp.

PublisherBase::ReturnCode RTC::PublisherNew::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:
dataData to be wrote to the buffer
secTimeout time in unit seconds
nsecTimeout 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.
