  org.perfectjpattern.core.structural.adapter.ExactMatchAdaptingStrategy

All Implemented Interfaces:

IStrategy, IAdaptingStrategy

Direct Known Subclasses:

NameMatchAdaptingStrategy

public class ExactMatchAdaptingStrategy
extends Object
implements IAdaptingStrategy

Concrete implementation of IAdaptingStrategy. Implements the exact matching strategy. The Adaptee and Target methods (name and parameters) must match or at least the Adaptee methods must be a subset of Target methods.

ExactMatchAdaptingStrategy()

Method Summary

Method	resolve(Class<?> aTargetClass, Object anAdaptee, Object anAdapter, Method aTargetMethod) Returns the Adaptee or otherwise Adapter method that corresponds to the given Target class type.
protected Method	resolve(Object anObject, Method aMethodPrototype) Returns the found matching Method if exists, null or NoSuchMethodError otherwise
protected Method	resolve(Object anObject, Method aMethodPrototype, String aMethodName) Returns the found matching Method if exists, null or NoSuchMethodError otherwise
void	validate(Class<?> aTargetClass, Object anAdaptee, Object anAdapter) According to the definition of this strategy validates the tuple Target/Adaptee.
protected void	validate(Class<?> anInterface, Object anImplementor, Set<String> aTargetMethods) Removes from aTargetMethods all methods found in anInterface that are actually implemented by anImplementor

Method Detail

validate

public void validate(Class<?> aTargetClass,
                     Object anAdaptee,
                     Object anAdapter)
              throws NoSuchMethodError

According to the definition of this strategy validates the tuple Target/Adaptee. Should the two not match an NoSuchMethodError will be thrown.

Specified by:

validate in interface IAdaptingStrategy

Parameters:

aTargetClass - Target class type

anAdaptee - Adaptee instance

anAdapter - Adapter instance

Throws:

NoSuchMethodError

resolve

public Method resolve(Class<?> aTargetClass,
                      Object anAdaptee,
                      Object anAdapter,
                      Method aTargetMethod)
               throws IllegalArgumentException,
                      NoSuchMethodError

Returns the Adaptee or otherwise Adapter method that corresponds to the given Target class type. If the corresponding method is not found an NoSuchMethodError will be thrown.

Specified by:

resolve in interface IAdaptingStrategy

Parameters:

aTargetClass - Target class type

anAdaptee - Adaptee instance

anAdapter - Adapter instance

aTargetMethod - Target method to search for in the Adaptee

Returns:

Adaptee method that corresponds to the given Target class type

Throws:

NoSuchMethodError

IllegalArgumentException

                        Object anImplementor,
                        Set<String> aTargetMethods)

Removes from aTargetMethods all methods found in anInterface that are actually implemented by anImplementor

Parameters:

anInterface - The target interface

anImplementor - The underlying implementor

aTargetMethods - The methods to search for

resolve
