Detailed Description
Base class of Publisher.
This is a base class of Publisher*. This class manages data send timing. Variation of Publisher* which implements details of Publisher inherits this PublisherBase class.
Constructor & Destructor Documentation
| virtual DATAPORTSTATUS_ENUM RTC::PublisherBase::~PublisherBase | ( | void | ) | [inline, virtual] |
Destructor.
Member Function Documentation
| virtual ReturnCode RTC::PublisherBase::activate | ( | ) | [pure virtual] |
activation
This function activates the publisher. By calling this function, this publisher starts 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.
- Returns:
- PORT_OK normal return PRECONDITION_NOT_MET precondition is not met
Implemented in RTC::PublisherFlush, RTC::PublisherNew, and RTC::PublisherPeriodic.
| virtual ReturnCode RTC::PublisherBase::deactivate | ( | ) | [pure virtual] |
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.
- Returns:
- PORT_OK normal return PRECONDITION_NOT_MET precondition is not met
Implemented in RTC::PublisherFlush, RTC::PublisherNew, and RTC::PublisherPeriodic.
| virtual ReturnCode RTC::PublisherBase::init | ( | coil::Properties & | prop | ) | [pure virtual] |
Initializing configuration.
This operation would be called to configure in initialization. In the concrete class, configuration should be performed getting appropriate information from the given Properties data. This function might be called right after instantiation and connection sequence respectivly. Therefore, this function should be implemented assuming multiple call.
- Parameters:
-
prop Configuration information
Implemented in RTC::PublisherFlush, RTC::PublisherNew, and RTC::PublisherPeriodic.
| virtual bool RTC::PublisherBase::isActive | ( | ) | [pure virtual] |
If publisher is active state.
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)
Implemented in RTC::PublisherFlush, RTC::PublisherNew, and RTC::PublisherPeriodic.
| virtual void RTC::PublisherBase::release | ( | ) | [inline, virtual] |
Release the Publisher.
Release this Publisher. When Publisher becomes unnecessary, this is invoked from PublisherFactory.
| virtual ReturnCode RTC::PublisherBase::setBuffer | ( | BufferBase< cdrMemoryStream > * | buffer | ) | [pure 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
| virtual ReturnCode RTC::PublisherBase::setConsumer | ( | InPortConsumer * | consumer | ) | [pure 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
Implemented in RTC::PublisherFlush, RTC::PublisherNew, and RTC::PublisherPeriodic.
| virtual ReturnCode RTC::PublisherBase::setListener | ( | ConnectorInfo & | info, | |
| ConnectorListeners * | listeners | |||
| ) | [pure virtual] |
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
Implemented in RTC::PublisherFlush, RTC::PublisherNew, and RTC::PublisherPeriodic.
| virtual ReturnCode RTC::PublisherBase::write | ( | const cdrMemoryStream & | data, | |
| unsigned long | sec, | |||
| unsigned long | usec | |||
| ) | [pure virtual] |
Write data.
This function writes data into the Publisher. If this function is called without initializing correctly such as a consumer, listeners, etc., error code PRECONDITION_NOT_MET will be returned and no operation of the writing etc. will be performed.
When publisher writes data, if the consumer returns full-status, returns error, is returned with timeout, error codes BUFFER_FULL, BUFFER_ERROR and BUFFER_TIMEOUT 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. SEND_FULL Data was sent but full-status returned SEND_TIMEOUT Data was sent but timeout occurred CONNECTION_LOST detected that the connection has been lost
Implemented in RTC::PublisherFlush, RTC::PublisherNew, and RTC::PublisherPeriodic.
