DataInputStatus
It is an internal equivalent of
InputStatus that provides
additional non public statuses. |
PushingAsyncDataInput
The variant of
PullingAsyncDataInput that is defined for handling both network input and
source input in a unified way via PushingAsyncDataInput.emitNext(DataOutput) instead of returning Optional.empty() via PullingAsyncDataInput.pollNext() . |
PushingAsyncDataInput.DataOutput
Basic data output interface used in emitting the next element from data input.
