getInvocationStrategy

protected InvocationStrategy<D,E,?> getInvocationStrategy(E object,
                                                          java.lang.reflect.Method method,

Description copied from class: AbstractInvocationHandler

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 DatabaseWriteInvocationStrategy.

Overrides:

getInvocationStrategy in class AbstractInvocationHandler<D,E>

Parameters:

object - the proxied object

method - the method to invoke

parameters - the method invocation parameters

Returns:

an invocation strategy

Throws:

java.lang.Exception

AbstractInvocationHandler.getInvocationStrategy(java.lang.Object, java.lang.reflect.Method, java.lang.Object[])

getDatabaseReadMethodSet

protected abstract java.util.Set<java.lang.reflect.Method> getDatabaseReadMethodSet()

postInvoke

protected void postInvoke(E object,
                          java.lang.reflect.Method method,
                          java.lang.Object[] parameters)

Description copied from class: AbstractInvocationHandler

Called after method is invoked.

Overrides:

postInvoke in class AbstractInvocationHandler<D,E>

Parameters:

object - the proxied object

method - the method that was just invoked

parameters - the parameters of the method that was just invoked

See Also:

AbstractInvocationHandler.postInvoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[])

close
