Constructor Detail

LocatorInvocationHandler

protected LocatorInvocationHandler(Class<T> proxyClass,
                        F proxyFactory,
                        Set<Method> readMethods,
                        Set<Method> writeMethods)

Method Detail

getInvocationStrategy

protected InvocationStrategy getInvocationStrategy(T locator,
                                       Method method,
                                       Object... parameters)
                                            throws SQLException

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.

Overrides:

getInvocationStrategy in class AbstractInvocationHandler<Z,D extends Database<Z>,T,SQLException,F extends LocatorProxyFactory<Z,D,P,T>>

Parameters:

locator - the proxied object

method - the method to invoke

parameters - the method invocation parameters

Returns:

an invocation strategy

Throws:

SQLException

postInvoke

protected <R> void postInvoke(Invoker<Z,D,T,R,SQLException> invoker,
                  T proxy,
                  Method method,
                  Object... parameters)

Overrides:

postInvoke in class AbstractInvocationHandler<Z,D extends Database<Z>,T,SQLException,F extends LocatorProxyFactory<Z,D,P,T>>
