Modifier and Type	Method and Description
static LastInvocationAware	getLastInvocationAware(Class<?> type, Method method, Object[] parameters) Creates a simple LastInvocationAware from the given type, method and parameters.
static LastInvocationAware	getLastInvocationAware(Method method, Object[] parameters) Creates a simple LastInvocationAware for the given method and parameters.
static LastInvocationAware	getLastInvocationAware(Object source) Returns the LastInvocationAware instance from the given source, that essentially has to be a proxy created via methodOn(Class, Object...) and subsequent linkTo(…) calls.
static <T> T	methodOn(Class<T> type, Object... parameters) Returns a proxy of the given type, backed by an EmptyTargetSource to simply drop method invocations but equips it with an InvocationRecordingMethodInterceptor.

Method Detail

methodOn

public static <T> T methodOn(Class<T> type,
                             Object... parameters)

Returns a proxy of the given type, backed by an EmptyTargetSource to simply drop method invocations but equips it with an InvocationRecordingMethodInterceptor. The interceptor records the last invocation and returns a proxy of the return type that also implements LastInvocationAware so that the last method invocation can be inspected. Parameters passed to the subsequent method invocation are generally neglected except the ones that might be mapped into the URI translation eventually, e.g. PathVariable in the case of Spring MVC. Note, that the return types of the methods have to be capable to be proxied.

Parameters:

type - must not be null.

parameters - parameters to extend template variables in the type level mapping.

Returns:

getLastInvocationAware

@Nullable
public static LastInvocationAware getLastInvocationAware(Object source)

Returns the LastInvocationAware instance from the given source, that essentially has to be a proxy created via methodOn(Class, Object...) and subsequent linkTo(…) calls.

Parameters:

source - must not be null.

Returns:

getLastInvocationAware

public static LastInvocationAware getLastInvocationAware(Method method,
                                                         Object[] parameters)

Creates a simple LastInvocationAware for the given method and parameters.

Parameters:

method - must not be null.

parameters - must not be null.

Returns:

will never be null.

Since:

1.3.4
