Instance Attribute Details

#incoming_bytes ⇒ Integer (readonly)

Returns The number of incomign bytes currently being buffered.

Returns:

  • (Integer) —

    The number of incomign bytes currently being buffered.

proton_caller :incoming_bytes

#incoming_capacity ⇒ Integer

The incoming capacity of a session determines how much incoming message data the session will buffer. Note that if this value is less than the negotatied frame size of the transport, it will be rounded up to one full frame.

Returns:

  • (Integer) —

    The incoing capacity of the session, measured in bytes.

#outgoing_bytes ⇒ Integer (readonly)

Returns The number of outgoing bytes currently being buffered.

Returns:

  • (Integer) —

    The number of outgoing bytes currently being buffered.

#state ⇒ Integer (readonly)

Returns The endpoint state.

Returns:

  • (Integer) —
