Detailed Description

Wrapper for ResponseHandler, used only internally to run next operation after previous one is finished

Constructor & Destructor Documentation

XrdCl::PipelineHandler::PipelineHandler	(	ResponseHandler *	handler,
		bool	own
	)

Constructor.

Parameters

handler	: the handler of our operation
own	: if true we have the ownership of handler (it's memory), and it is our responsibility to deallocate it

XrdCl::PipelineHandler::PipelineHandler

(

)

Default Constructor.

XrdCl::PipelineHandler::~PipelineHandler

(

)

Destructor.

Member Function Documentation

void XrdCl::PipelineHandler::AddOperation

(

Operation< true > *

operation

)

Add new operation to the pipeline

Parameters

operation

: operation to add

void XrdCl::PipelineHandler::Assign	(	std::promise< XRootDStatus >	prms,
		std::function< void(const XRootDStatus &)>	final
	)

Set workflow to this and all next handlers. In the last handler it is used to finish workflow execution

Parameters

prms	: a promis that the pipeline will have a result
final	: a callable that should be called at the end of pipeline

void XrdCl::PipelineHandler::dealloc ( XRootDStatus *  status, AnyObject *  response, HostList *  hostList  )

inlineprivate

void XrdCl::PipelineHandler::HandleResponse ( XRootDStatus *  status, AnyObject *  response  )
