                                            throws E extends Exception

Returns the appropriate InvocationStrategy for the specified method. This implementation detects Wrapper methods; and Object.equals(java.lang.Object), Object.hashCode(), and Object.toString(). Default invocation strategy is AllResultsCollector.

Parameters:

object - the proxied object

method - the method to invoke

parameters - the method invocation parameters

Returns:

an invocation strategy

Throws:

E

E extends Exception

getInvoker

protected <R> Invoker<Z,D,T,R,E> getInvoker(T proxy,

Return the appropriate invoker for the specified method.

Parameters:

proxy -

method -

parameters -

Returns:

an invoker

Throws:

Exception
