Member Function Documentation

virtual void epics::pvAccess::ChannelArrayRequester::channelArrayConnect ( const epics::pvData::Status &  status, ChannelArray::shared_pointer const &  channelArray, epics::pvData::Array::const_shared_pointer const &  array  )

pure virtual

Underlying Channel is connected and operation setup is complete. May call putArray(), getArray(), getLength(), or setLength() to execute.

Parameters

status	Completion status.
channelArray	The channelArray interface or nullptr if the request failed.
pvArray	The PVArray that holds the data or nullptr if the request failed.

Implemented in epics::pvAccess::ServerChannelArrayRequesterImpl.

virtual void epics::pvAccess::ChannelArrayRequester::getArrayDone ( const epics::pvData::Status &  status, ChannelArray::shared_pointer const &  channelArray, epics::pvData::PVArray::shared_pointer const &  pvArray  )

pure virtual

The request is done. This is always called with no locks held.

Ownership of the PVArray is transfered to the ChannelArrayRequester until a subsequent call to ChannelArray::getArray() or ChannelArrayRequester::channelDisconnect().

Parameters

status	Completion status.
channelArray	The channelArray interface.
pvArray	The PVArray that holds the data or nullptr if the request failed.

Implemented in epics::pvAccess::ServerChannelArrayRequesterImpl.

virtual void epics::pvAccess::ChannelArrayRequester::getLengthDone ( const epics::pvData::Status &  status, ChannelArray::shared_pointer const &  channelArray, size_t  length  )

pure virtual

The request is done. This is always called with no locks held.

Parameters

status	Completion status.
channelArray	The channelArray interface.
length	The length of the array, 0 if the request failed.

)

virtual void epics::pvAccess::ChannelArrayRequester::putArrayDone ( const epics::pvData::Status &  status, ChannelArray::shared_pointer const &  channelArray  )

pure virtual

The request is done. This is always called with no locks held.

Ownership of PVArray passed to ChannelArray::putArray() returns to ChannelArrayRequester

Parameters

status	Completion status.
channelArray	The channelArray interface.

Implemented in epics::pvAccess::ServerChannelArrayRequesterImpl.

virtual void epics::pvAccess::ChannelArrayRequester::setLengthDone ( const epics::pvData::Status &  status, ChannelArray::shared_pointer const &  channelArray  )

pure virtual

The request is done. This is always called with no locks held.

Parameters

status	Completion status.
channelArray	The channelArray interface.

Implemented in epics::pvAccess::ServerChannelArrayRequesterImpl.
