Method Detail

setChannelBindingsContextLookupStrategy

public void setChannelBindingsContextLookupStrategy(@Nonnull
                                                    Function<MessageContext,ChannelBindingsContext> strategy)

Set the strategy used to locate the ChannelBindingsContext to operate on.

Parameters:

strategy - lookup strategy

doPreInvoke

protected boolean doPreInvoke(@Nonnull
                              MessageContext messageContext)
                       throws MessageHandlerException

Called prior to execution, handlers may override this method to perform pre-processing for a request.

The default impl applies the Predicate set via the AbstractMessageHandler.setActivationCondition(Predicate).

If false is returned, execution will not proceed.

Subclasses which override this method should generally invoke the super version of this method first, so that the activation condition will be applied up front, and immediately return false if the super version returns false. This avoids unnecessary execution of the remaining pre-invocation code if the handler ultimately will not execute.

Overrides:

doPreInvoke in class AbstractMessageHandler

Parameters:

messageContext - the message context on which to invoke the handler

Returns:

true iff execution should proceed

Throws:

MessageHandlerException - if there is a problem executing the handler pre-routine

doInvoke

protected void doInvoke(@Nonnull
                        MessageContext messageContext)
                 throws MessageHandlerException

Performs the handler logic.

Specified by:

doInvoke in class AbstractMessageHandler

Parameters:

messageContext - the message context on which to invoke the handler

Throws:

MessageHandlerException - if there is an error invoking the handler on the message context
