Method Details

getHandlers

@NonnullAfterInit
@Unmodifiable
@NotLive
public List<MessageHandler> getHandlers()

Get the ordered list of message handlers which comprise the handler chain.

The returned list is immutable. Changes to the list should be accomplished through setHandlers(List).

Specified by:

getHandlers in interface MessageHandlerChain

Returns:

the list of members of the handler chain

setHandlers

public void setHandlers(@Nullable
 List<MessageHandler> handlers)

Set the list of message handler chain members.

The supplied list is copied before being stored. Later modifications to the originally supplied list will not be reflected in the handler chain membership.

Parameters:

handlers - the list of message handler members

doInvoke

public void doInvoke(@Nonnull
 MessageContext msgContext)
              throws MessageHandlerException

Performs the handler logic.

Specified by:
