Member Function Documentation

void DispatchHandlerOperationSetState::initialize

(

)

Pre-request initialization.

This method calls SystemState::get() to populate m_specs and m_generation, and starts m_timer.

Definition at line 44 of file DispatchHandlerOperationSetState.cc.

void DispatchHandlerOperationSetState::start ( const String &  location )

virtual

Issues a RangeServer::set_state() request to a range server.

This method makes an asynchronous call to RangeServer::set_state()

Parameters

location

Proxy name of server

Implements Hypertable::DispatchHandlerOperation.
