Method Detail

invokeNext

public Object invokeNext()
                  throws Throwable

Invoke on the next interceptor in the chain. If this is already the end of the chain, reflection will call the constructor, field, or method you are invoking on.

Specified by:

invokeNext in interface Invocation

Overrides:

invokeNext in class InvocationBase

Throws:

Throwable

invokeTarget

public Object invokeTarget()
                    throws Throwable

Invokes the target joinpoint for this invocation skipping any subsequent interceptors in the chain.

Specified by:

invokeTarget in interface Invocation

Overrides:

invokeTarget in class InvocationBase

Throws:

Throwable

getWrapper

public Invocation getWrapper(Interceptor[] newchain)

Get a wrapper invocation object that can insert a new chain of interceptors at runtime to the invocation flow. CFlow makes use of this. When the wrapper object finishes its invocation chain it delegates back to the wrapped invocation.

Parameters:

newchain -

Returns:

copy

public Invocation copy()

Copies complete state of Invocation object.

Returns:

getValue

public Object getValue()

setValue

public void setValue(Object value)
