Constructor & Destructor Documentation

Hyperspace::RequestHandlerAttrExists::RequestHandlerAttrExists ( Comm *  comm, Master *  master, uint64_t  session_id, EventPtr &  event  )

inline

Constructor.

Initializes object by passing event into parent constructor, setting m_comm to comm, m_master to master, and m_session_id to session_id.

Parameters

comm	Comm instance
master	Master pointer
session_id	Session ID
event	Event object generating request

Member Function Documentation

void RequestHandlerAttrExists::run ( )

virtual

Unmarshalls request parameters and calls Master::attr_exists().

This method unmarshalls request parameters from the originating Event object and passes them into a call to Master::attr_exists(). See Protocol::create_attr_exists_request() for the request parameter encoding format.

Implements Hypertable::ApplicationHandler.
