org.logicalcobwebs.proxool.proxy.MethodMapper

public class MethodMapper
extends Object

Handles the mapping between methods with identical signatures but that are not related by inheritance. This allows you to invoke a method on a class using an interface that it doesn't actually implement. It caches the result of its reflective lookup to save time. If the concreteClass does in fact implement the injectable interface then it quickly returns the method without the penalty of mapping using reflection.

MethodMapper

public MethodMapper(Class concreteClass)

参数:

concreteClass - the class that we want to invoke methods on. It should either implement all methods on the injectable interface, or provide methods with an identical signature.

方法详细资料

getConcreteMethod

protected Method getConcreteMethod(Method injectableMethod)
                            throws ProxoolException

Returns the method in the concrete class with an indentical signature to that passed as a parameter

参数:

injectableMethod - provides signature that we are trying to match

返回:

the method in the concrete class that we can invoke as if it were in the interface

抛出:

ProxoolException - if the method is not found.

overrideConcreteMethod

public void overrideConcreteMethod(Method injectableMethod,
                                   Method overridenMethod)

Don't use the one we calculate using getConcreteMethod(java.lang.reflect.Method), use this one instead.

参数:

injectableMethod - the method supplied by the proxy

overridenMethod - the one we are going to use (probably the same as injectrableMethod actually)
