Method Detail

asResetContext

public static <T> ResetContext<T> asResetContext(Object messageOrPayload)

Returns the given messageOrPayload as a ResetContext. If messageOrPayload already implements ResetContext, it is returned as-is. If it implements Message, messageOrPayload will be cast to Message and current time is used to create a ResetContext. Otherwise, the given messageOrPayload is wrapped into a GenericResetContext as its payload.

Type Parameters:

T - the type of payload contained in the message

Parameters:

messageOrPayload - the payload to wrap or cast as ResetContext

Returns:

a ResetContext containing given messageOrPayload as payload, or the messageOrPayload if it already implements ResetContext.
