Method Detail

resume

public void resume()

Description copied from interface: Continuation

Resume the request. Resume a suspended request. The passed event will be returned in the getObject method.

Specified by:

resume in interface Continuation

isNew

public boolean isNew()

Description copied from interface: Continuation

Is this a newly created Continuation.

A newly created continuation has not had #getEvent(long) called on it.

Specified by:

isNew in interface Continuation

Returns:

True if the continuation has just been created and has not yet suspended the request.

suspend

public boolean suspend(long timeout)

Description copied from interface: Continuation

Suspend handling. This method will suspend the request for the timeout or until resume is called.

Specified by:

suspend in interface Continuation

Returns:

True if resume called or false if timeout.

isPending

public boolean isPending()

Description copied from interface: Continuation

Get the pending status? A continuation is pending while the handling of a call to suspend has not completed. For blocking continuations, pending is true only during the call to Continuation.suspend(long). For non-blocking continuations, pending is true until a second call to Continuation.suspend(long), thus this method can be used to determine if a request is being retried.

Specified by:

isPending in interface Continuation

Returns:

True if the continuation is handling a call to suspend.

getObject

public Object getObject()

Description copied from interface: Continuation

Arbitrary object associated with the continuation for context.

Specified by:

getObject in interface Continuation

Returns:

An arbitrary object associated with the continuation

setObject

public void setObject(Object object)

Description copied from interface: Continuation

Arbitrary object associated with the continuation for context.

Specified by:

setObject in interface Continuation

Parameters:

object - An arbitrary object to associate with the continuation

getMutex

public Object getMutex()

setMutex

public void setMutex(Object mutex)
