接口 Selector<R,C,E>

所有超级接口:
Serializable
所有已知实现类:
AbstractCmdbSelector, AbstractSelector, ExpressionSelector, NoneSelector
public interface Selector<R,C,E> extends Serializable
The Selector mainly work on the logic of parse and select. parse(Object) allow user accept the condition which provided by Nacos to build the select(Object) judge logic. select(Object) allow user to execute the logic to get the target result they want. getType() will return the type. getContextType() will return the context type which used by select(Object).

Now, Nacos only provide the AbstractCmdbSelector for user to implement their own select logic. Other type is waiting.
