      org.perfectjpattern.core.structural.adapter.NameMatchAdaptingStrategy

All Implemented Interfaces:

IStrategy, IAdaptingStrategy

public final class NameMatchAdaptingStrategy
extends ExactMatchAdaptingStrategy
implements IAdaptingStrategy

Concrete implementation of IAdaptingStrategy. Implements the name matching strategy. The Adaptee and Target methods are matched by name. The method correspondence is provided by the user as a Map of Target method names keyed by Adaptee method names. The mapping does not have to be exhaustive, those methods not explicitly mapped will be resolved against the Adaptee and Adapter using exact match.

Constructor Detail

NameMatchAdaptingStrategy

public NameMatchAdaptingStrategy(Map<String,String> aMethodsMapping)

Constructs a NameMatchAdaptingStrategy from a map that defines the correspondence between Target and Adaptee i.e. Adaptee method names keyed by Target method names.

Parameters:

aMethodsMapping - Map of Target method names keyed by Target method names

Throws:

IllegalArgumentException - 'aMethodsMap' must not be null

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

Overrides:

validate in class ExactMatchAdaptingStrategy

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

Overrides:

resolve in class ExactMatchAdaptingStrategy

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
