Interface HandlerInterceptor.PreparedHandlerInterceptor

Enclosing interface:

HandlerInterceptor

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface HandlerInterceptor.PreparedHandlerInterceptor

A handler-method-specific interceptor plan. Plans are created once and may be invoked concurrently.

Field Summary

Fields

Modifier and Type	Field	Description
static final HandlerInterceptor.PreparedHandlerInterceptor	noOp	A prepared no-op policy that proceeds directly to the next function.

Method Summary

Modifier and Type	Method	Description
Object	interceptHandling(DeserializingMessage message, HandlerDescriptor handler, BiFunction<Object,Object,Object> combiner, HandlerInterceptor.PreparedHandlerFunction next)	Intercepts one handling operation using previously prepared handler metadata.
default Function<DeserializingMessage, Object>	interceptHandling(Function<DeserializingMessage, Object> function, HandlerInvoker invoker)	Adapts this prepared interceptor to the original function-based interceptor contract.
default boolean	supportsHandlerMethod()	Whether this plan can safely wrap a reusable HandlerMethod.

Field Details

noOp

static final HandlerInterceptor.PreparedHandlerInterceptor noOp

A prepared no-op policy that proceeds directly to the next function.

Method Details

interceptHandling

Object interceptHandling(DeserializingMessage message,
 HandlerDescriptor handler,
 BiFunction<Object,Object,Object> combiner,
 HandlerInterceptor.PreparedHandlerFunction next)

Intercepts one handling operation using previously prepared handler metadata.

Parameters:

message - current message

handler - the resolved per-message invoker or reusable handler method

combiner - result combiner supplied to the handler

next - the remaining prepared handling chain

Returns:

the handling result

interceptHandling

default Function<DeserializingMessage, Object> interceptHandling(Function<DeserializingMessage, Object> function,
 HandlerInvoker invoker)

Adapts this prepared interceptor to the original function-based interceptor contract.

Parameters:

function - next handling function

invoker - resolved handler invoker

Returns:

an intercepted handling function

supportsHandlerMethod

default boolean supportsHandlerMethod()

Whether this plan can safely wrap a reusable HandlerMethod. Implementations returning true must depend only on the supplied descriptor and message, not on mutable state of a per-message invoker.

Returns:

true when the plan supports reusable handler methods
