OutPortPullConnector class
Connector class of OutPort for pull type dataflow. When "pull" is specified as dataflow_type at the time of establishing connection, this object is generated and owned by the OutPort. This connector and InPortPullConnector make a pair and realize pull type dataflow of data ports. One connector corresponds to one connection which provides a data stream. Connector is distinguished by ID of the UUID that is generated at establishing connection.
OutPortPullConnector owns and manages the following objects.
Data written into the OutPort is passed to OutPortPullConnector::write(), and it is written into the buffer. By reading data from OutPortPullConnector to InPortPullConnector, data transfer is realized.

Constructor
OutPortPullConnector's constructor is given the following arguments. According to ConnectorInfo which includes connection information, a buffer is created. It is also given a pointer to the provider object for the OutPort interface. The owner-ship of the pointer is owned by this OutPortPullConnector, it has responsibility to destruct the OutPortProvider. OutPortPullConnector also has ConnectorListeners to provide event callback mechanisms, and they would be called at the proper timing. If data buffer is given by OutPortBase, the pointer to the buffer is also given as arguments.

def OpenRTM_aist.OutPortPullConnector.OutPortPullConnector.__del__ | ( | self | ) |
Destructor
This operation calls disconnect(), which destructs and deletes the consumer, the publisher and the buffer.
Reimplemented from OpenRTM_aist.OutPortConnector.OutPortConnector.

Connector activation
This operation activates this connector
virtual void activate(){}; // do nothing
Reimplemented from OpenRTM_aist.ConnectorBase.ConnectorBase.
def OpenRTM_aist.OutPortPullConnector.OutPortPullConnector.createBuffer | ( | self, | |
info | |||
) |
create buffer
CdrBufferBase* createBuffer(ConnectorInfo& info);
def OpenRTM_aist.OutPortPullConnector.OutPortPullConnector.deactivate | ( | self | ) |
Connector deactivation
This operation deactivates this connector
virtual void deactivate(){}; // do nothing
Reimplemented from OpenRTM_aist.ConnectorBase.ConnectorBase.
def OpenRTM_aist.OutPortPullConnector.OutPortPullConnector.disconnect | ( | self | ) |
disconnect
This operation destruct and delete the consumer, the publisher and the buffer.
virtual ReturnCode disconnect();
Reimplemented from OpenRTM_aist.ConnectorBase.ConnectorBase.
def OpenRTM_aist.OutPortPullConnector.OutPortPullConnector.getBuffer | ( | self | ) |
Getting Buffer
This operation returns this connector's buffer
virtual CdrBufferBase* getBuffer();
Reimplemented from OpenRTM_aist.ConnectorBase.ConnectorBase.
def OpenRTM_aist.OutPortPullConnector.OutPortPullConnector.onConnect | ( | self | ) |
Invoke callback when connection is established void onConnect()
def OpenRTM_aist.OutPortPullConnector.OutPortPullConnector.onDisconnect | ( | self | ) |
Invoke callback when connection is destroied void onDisconnect()
def OpenRTM_aist.OutPortPullConnector.OutPortPullConnector.setDirectMode | ( | self | ) |
void onDisconnect()
Reimplemented from OpenRTM_aist.OutPortConnector.OutPortConnector.
def OpenRTM_aist.OutPortPullConnector.OutPortPullConnector.write | ( | self, | |
data | |||
) |
Writing data
This operation writes data into publisher and then the data will be transferred to correspondent InPort.
virtual ReturnCode write(const cdrMemoryStream& data);
