Synopsis

Declared in <folly/io/async/observer/AsyncSocketObserverInterface.h>

class AsyncSocketObserverInterface;

Name	Description
`ByteEvent`	Structure used to communicate ByteEvents, such as TX and ACK timestamps.
`PrewriteRequest`	Request that can be generated by observer in response to prewrite event.
`PrewriteRequestContainer`	Container of PrewriteRequests passed on invocation of prewrite().
`PrewriteState`	Information provided to observer during prewrite event.

Name	Description
`Events`	Set of interface events an observer can subscribe to.

Name	Description
`AsyncSocketObserverInterface` [constructor]	Constructs the observer interface.
`~AsyncSocketObserverInterface` [destructor] [virtual]	Destroys the observer interface.
`byteEvent` [virtual]	Invoked each time a ByteEvent is available.
`byteEventsEnabled` [virtual]	Invoked if ByteEvents are enabled.
`byteEventsUnavailable` [virtual]	Invoked if ByteEvents could not be enabled, or if an error occurred that will prevent further delivery of ByteEvents.
`close` [virtual]	close() will be invoked when the socket is being closed.
`connectAttempt` [virtual]	connectAttempt() will be invoked when connect() is called.
`connectError` [virtual]	connectError() will be invoked when connect() returns an error.
`connectSuccess` [virtual]	connectSuccess() will be invoked when connect() returns successfully.
`evbAttach` [virtual]	Invoked when the socket is being attached to an EventBase.
`evbDetach` [virtual]	Invoked when the socket is being detached from an EventBase.
`fdAttach` [virtual]	fdAttach() is invoked when the socket file descriptor is attached.
`fdDetach` [virtual]	fdDetach() is invoked if the socket file descriptor is detached.
`move` [virtual]	move() will be invoked when a new AsyncSocket is being constructed via constructor AsyncSocket(AsyncSocket* oldAsyncSocket) from an AsyncSocket that has an observer attached.
`prewrite` [virtual]	Invoked before each write to the socket if prewrite support enabled.

Name	Description
`LegacyLifecycleObserver`	Observer of socket events.
