An interface for metadata redirectors.

Constructor & Destructor Documentation

~VirtualRedirector()

virtual XrdCl::VirtualRedirector::~VirtualRedirector ( )

inlinevirtual

Destructor.

Member Function Documentation

Count()

virtual int XrdCl::VirtualRedirector::Count ( Message &  req ) const

pure virtual

Count how many replicas do we have left to try for given request.

Implemented in XrdCl::MetalinkRedirector.

GetCheckSum()

virtual std::string XrdCl::VirtualRedirector::GetCheckSum ( const std::string &  type ) const

pure virtual

Returns the checksum of the given type if specified in the metalink file, or an empty string otherwise

Implemented in XrdCl::MetalinkRedirector.

GetReplicas()

virtual const std::vector< std::string > & XrdCl::VirtualRedirector::GetReplicas ( )

pure virtual

Returns a vector with replicas as given in the meatlink file.

Implemented in XrdCl::MetalinkRedirector.

GetSize()

virtual long long XrdCl::VirtualRedirector::GetSize ( ) const

pure virtual

Returns the file size as specified in the metalink, or a negative number if size was not specified

Implemented in XrdCl::MetalinkRedirector.

GetSupportedCheckSums()

virtual std::vector< std::string > XrdCl::VirtualRedirector::GetSupportedCheckSums ( ) const

pure virtual

Returns the default checksum type (the first one given in the metalink), if no checksum is available returns an empty string

Implemented in XrdCl::MetalinkRedirector.

GetTargetName()

virtual std::string XrdCl::VirtualRedirector::GetTargetName ( ) const

pure virtual

Gets the file name as specified in the metalink.

Implemented in XrdCl::MetalinkRedirector.

HandleRequest()

virtual XRootDStatus XrdCl::VirtualRedirector::HandleRequest ( const Message *  msg, MsgHandler *  handler  )

pure virtual

Creates an instant redirect response for the given message or an error response if there are no more replicas to try. The virtual response is being handled by the given handler in the thread-pool.

Implemented in XrdCl::MetalinkRedirector.

Load()

virtual XRootDStatus XrdCl::VirtualRedirector::Load ( ResponseHandler *  userHandler )

pure virtual

Initializes the object with the content of the metalink file.

Implemented in XrdCl::MetalinkRedirector.
