Method Summary

Modifier and Type	Method and Description
int	accept(java.lang.reflect.Method method) To keep the generated class light enough we define which methods we'd like to intercept here.
protected java.lang.Object	after(Item i, java.lang.reflect.Method m, java.lang.Object[] originalArgs, java.lang.Object[] args, java.lang.Object returned) Called after the actual method call.
protected java.lang.Object[]	before(Item p, java.lang.reflect.Method m, java.lang.Object[] args) Called before the actual method call.
protected java.lang.Object	call(Item obj, java.lang.Object[] args, MethodProxy proxy)
BridgeAbstraction	createInstance(Tenant tenant, BridgeInterface impl) Here we're creating a jalo item instance.
java.lang.Object	intercept(java.lang.Object obj, java.lang.reflect.Method method, java.lang.Object[] args, MethodProxy methodproxy) Intercepts all target method calls and wraps the actual call into before(Item, Method, Object[]) and after(Item, Method, Object[], Object[], Object).

Method Detail

intercept

public final java.lang.Object intercept(java.lang.Object obj,
                                        java.lang.reflect.Method method,
                                        java.lang.Object[] args,
                                        MethodProxy methodproxy)
                                 throws java.lang.Throwable

Intercepts all target method calls and wraps the actual call into before(Item, Method, Object[]) and after(Item, Method, Object[], Object[], Object).

Throws:

java.lang.Throwable

before

protected java.lang.Object[] before(Item p,
                                    java.lang.reflect.Method m,
                                    java.lang.Object[] args)

Called before the actual method call. It is possible to return different arguments here. By default this method simply returns the original arguments.

Parameters:

m - the method

args - the original arguments

Returns:

the arguments to be used for calling the actual method

after

protected java.lang.Object after(Item i,
                                 java.lang.reflect.Method m,
                                 java.lang.Object[] originalArgs,
                                 java.lang.Object[] args,
                                 java.lang.Object returned)

Called after the actual method call. By default this method simply passes on the original result.

Parameters:

i - the item

m - the method

originalArgs - the original arguments before the call

args - the arguments used for the actual call

returned - the result of the actual call

Returns:

the result to be returned as method call result

call

protected java.lang.Object call(Item obj,
                                java.lang.Object[] args,
                                MethodProxy proxy)
                         throws java.lang.Throwable

Throws:

java.lang.Throwable

createInstance

public BridgeAbstraction createInstance(Tenant tenant,
                                        BridgeInterface impl)

Here we're creating a jalo item instance. Later on it will be connected to its persistence delegate so don't try to invoke any business method here !

Specified by:

createInstance in interface JaloObjectCreator

accept

public int accept(java.lang.reflect.Method method)

To keep the generated class light enough we define which methods we'd like to intercept here. This method maps untouched methods to 0 and all intercepted methods to 1 according to the configured callbacks inside our Enhancer.
