Class DatanodeHttpServer.MapBasedFilterConfig

java.lang.Object

org.apache.hadoop.hdfs.server.datanode.web.DatanodeHttpServer.MapBasedFilterConfig

All Implemented Interfaces:

javax.servlet.FilterConfig

Enclosing class:

DatanodeHttpServer

public static final class DatanodeHttpServer.MapBasedFilterConfig
extends Object
implements javax.servlet.FilterConfig

Since the DataNode HTTP server is not implemented in terms of the servlet API, it takes some extra effort to obtain an instance of the filter. This method provides a minimal FilterConfig implementation backed by a Map. Call this from your filter handler to initialize a servlet filter.
