程序包 com.alibaba.nacos.api.selector

类 AbstractCmdbSelector<T extends Instance>

java.lang.Object

com.alibaba.nacos.api.selector.AbstractCmdbSelector<T>

所有已实现的接口:

Selector<List<T>,CmdbContext<T>,String>, Serializable

public abstract class AbstractCmdbSelector<T extends Instance>
extends Object
implements Selector<List<T>,CmdbContext<T>,String>

AbstractCmdbSelector will provide one default implement of Selector, users can implement it to use the CmdbContext. And return the result as default subclass of Instance.
