eclipse 适配器 模式的使用

?

最原始的方法

public class Person  implements IPropertySource  

适配的方法 

public class Person implements IAdaptable {

public Object getAdapter(Class adapter) {

if (adapter == IPropertySource.class) return new PersonPropertySource(this);return null;

}

}

使用扩展点来实现适配

<plugin>   <extension         point="org.eclipse.core.runtime.adapters">      <factory            adaptableType="org.eclipse.articles.adapters.core.Person"            class="org.eclipse.articles.adapters.properties.PersonPropertiesSourceAdapterFactory">         <adapter               type="org.eclipse.ui.views.properties.IPropertySource">         </adapter>      </factory>   </extension></plugin>

public class PersonPropertiesSourceAdapterFactory implements IAdapterFactory {public Object getAdapter(Object adaptableObject, Class adapterType) {if (adapterType == IPropertySource.class)return new PersonPropertySource((Person)adaptableObject);return null;}public Class[] getAdapterList() {return new Class[] {IPropertySource.class};}}

public class Person implements IAdaptable {private String name;private Object street;private Object city;public Person(String name) {this.name = name;this.street = "";this.city = "";}public Object getAdapter(Class adapter) {return Platform.getAdapterManager().getAdapter(this, adapter);}}
