类 EmptyDataSource

java.lang.Object

com.alibaba.csp.sentinel.datasource.EmptyDataSource

所有已实现的接口:

ReadableDataSource<Object,Object>

public final class EmptyDataSource
extends Object
implements ReadableDataSource<Object,Object>

A ReadableDataSource based on nothing. getProperty() will always return the same cached SentinelProperty that doing nothing.
This class is used when we want to use default settings instead of configs from the ReadableDataSource.
