 org.apache.hbase.thirdparty.com.google.protobuf.Service service,
 String methodName,
 org.apache.hbase.thirdparty.com.google.protobuf.Message request)
                                                                              throws IOException

Description copied from interface: EndpointObserver

Called before an Endpoint service method is invoked. The request message can be altered by returning a new instance. Throwing an exception will abort the invocation. Calling ObserverContext.bypass() has no effect in this hook.

Specified by:

preEndpointInvocation in interface EndpointObserver

Parameters:

ctx - the environment provided by the region server

service - the endpoint service

methodName - the invoked service method

request - Request message expected by given Service's method (by the name methodName).

Returns:

the possibly modified message

Throws:

IOException
