Interface for releasing a connection. This can be implemented by various "trigger" objects which are associated with a connection, for example a EofSensorInputStream or the ManagedHttpClientConnection itself. 

The methods in this interface can safely be called multiple times.
The first invocation releases the connection, subsequent calls
are ignored.
Since:
