      • ReflectiveMethodInvocation

        protected ReflectiveMethodInvocation​(Object proxy,
                                             Object target,
                                             Method method,
                                             Object[] arguments,
                                             Class<?> targetClass,
                                             List<Object> interceptorsAndDynamicMethodMatchers)
        Construct a new ReflectiveMethodInvocation with the given arguments.
        Parameters:
        proxy - the proxy object that the invocation was made on
        target - the target object to invoke
        method - the method to invoke
        arguments - the arguments to invoke the method with
        targetClass - the target class, for MethodMatcher invocations
        interceptorsAndDynamicMethodMatchers - interceptors that should be applied, along with any InterceptorAndDynamicMethodMatchers that need evaluation at runtime. MethodMatchers included in this struct must already have been found to have matched as far as was possibly statically. Passing an array might be about 10% faster, but would complicate the code. And it would work only for static pointcuts.
    • Method Detail

      • getThis

        public final Object getThis()
        Description copied from interface: Joinpoint
        Return the object that holds the current joinpoint's static part.

        For instance, the target object for an invocation.

        Specified by:
        getThis in interface Joinpoint
        Returns:
        the object (can be null if the accessible object is static)
      • getMethod

        public final Method getMethod()
        Return the method invoked on the proxied interface. May or may not correspond with a method invoked on an underlying implementation of that interface.
        Specified by:
        getMethod in interface MethodInvocation
        Returns:
        the method being called
      • getArguments

        public final Object[] getArguments()
        Description copied from interface: Invocation
        Get the arguments as an array object. It is possible to change element values within this array to change the arguments.
        Specified by:
        getArguments in interface Invocation
        Returns:
        the argument of the invocation
      • proceed

        public Object proceed()
                       throws Throwable
        Description copied from interface: Joinpoint
        Proceed to the next interceptor in the chain.

        The implementation and the semantics of this method depends on the actual joinpoint type (see the children interfaces).

        Specified by:
        proceed in interface Joinpoint
        Returns:
        see the children interfaces' proceed definition
        Throws:
        Throwable - if the joinpoint throws an exception
      • invokeJoinpoint

        protected Object invokeJoinpoint()
                                  throws Throwable
        Invoke the joinpoint using reflection. Subclasses can override this to use custom invocation.
        Returns:
        the return value of the joinpoint
        Throws:
        Throwable - if invoking the joinpoint resulted in an exception
      • invocableClone

        public MethodInvocation invocableClone()
        This implementation returns a shallow copy of this invocation object, including an independent copy of the original arguments array.

        We want a shallow copy in this case: We want to use the same interceptor chain and other object references, but we want an independent value for the current interceptor index.

        Specified by:
        invocableClone in interface ProxyMethodInvocation
        Returns:
        an invocable clone of this invocation. proceed() can be called once per clone.
        See Also:
        Object.clone()
      • invocableClone

        public MethodInvocation invocableClone​(Object... arguments)
        This implementation returns a shallow copy of this invocation object, using the given arguments array for the clone.

        We want a shallow copy in this case: We want to use the same interceptor chain and other object references, but we want an independent value for the current interceptor index.

        Specified by:
        invocableClone in interface ProxyMethodInvocation
        Parameters:
        arguments - the arguments that the cloned invocation is supposed to use, overriding the original arguments
        Returns:
        an invocable clone of this invocation. proceed() can be called once per clone.
        See Also:
        Object.clone()
      • setUserAttribute

        public void setUserAttribute​(String key,
                                     Object value)
        Description copied from interface: ProxyMethodInvocation
        Add the specified user attribute with the given value to this invocation.

        Such attributes are not used within the AOP framework itself. They are just kept as part of the invocation object, for use in special interceptors.

        Specified by:
        setUserAttribute in interface ProxyMethodInvocation
        Parameters:
        key - the name of the attribute
        value - the value of the attribute, or null to reset it
      • getUserAttributes

        public Map<String,​ObjectgetUserAttributes()
        Return user attributes associated with this invocation. This method provides an invocation-bound alternative to a ThreadLocal.

        This map is initialized lazily and is not used in the AOP framework itself.

        Returns:
        any user attributes associated with this invocation (never null)
