    Class BaseTransferAbstract

    Base abstract class for all transfers. Implements CommunicationContractInterface via boolean capability flags.

    Flags determine which methods and interfaces a specific transfer implements:

    • isInput / isOutput — flow direction (input/output/duplex)
    • isPushable / isPullable / isSubscribable — data delivery mechanics
    • isTriggerable — presence of a manual trigger
    • isGate — presence of state management (activate/deactivate)
    • isPollingSource — presence of an external poller (polling)
    • isPollingProxy — ability to poll another transfer (polling)
    • isDuplex (computed) — true if isInput && isOutput

    All flags default to false. Subclasses override the needed ones to true.

    Each subclass must implement destroy(), which can lead to errors if the developer forgets to call super.destroy() to clean up _state.
