Understanding Handler States

This section provides information about the Handler states.

To get understanding in which state the Handler currently is, it's necessary to implement OnixS::SURF::MarketData::HandlerStateListener class interface and associate an instance with the Handler using OnixS::SURF::MarketData::Handler::registerHandlerStateListener member.

Below table describes all possible states for the Handler:

State	Description
OnixS::SURF::MarketData::HandlerState::Disconnected	The Handler is disconnected or was not executed yet.
OnixS::SURF::MarketData::HandlerState::Disconnecting	The intermediate state when the Handler is not disconnected but not connected.
OnixS::SURF::MarketData::HandlerState::Connected	The Handler is connected.
OnixS::SURF::MarketData::HandlerState::Connecting	The intermediate state when the Handler is not connected but not disconnected.
