PROOF kernel Libraries

The PROOF kernel libraries (libProof, libProofPlayer, libProofDraw) contain the classes defining the kernel of the PROOF facility, i.e.

the protocol and the utilities to steer data processing and handling of results.

Classes
class	TDrawFeedback
	Utility class to draw objects in the feedback list during queries. More...
class	TDSet
	This class implements a data set to be used for PROOF processing. More...
class	TDSetElement
	Manages an element of a TDSet. More...
class	TEventIter
	Special iterator class used in TProofPlayer to iterate over events or objects in the packets. More...
class	TLockPath
	Path locking class allowing shared and exclusive locks. More...
class	TOutputListSelectorDataMap
	Set the selector's data members to the corresponding elements of the output list. More...
class	TPacketizer
	This class generates packets to be processed on PROOF worker servers. More...
class	TPacketizerAdaptive
	This packetizer is based on TPacketizer but uses different load-balancing algorithms and data structures. More...
class	TPacketizerFile
	This packetizer generates packets which contain a single file path to be used in process. More...
class	TPacketizerMulti
	This class allows to do multiple runs in the same query; each run can be a, for example, different dataset or the same dataset with entry list. More...
class	TPacketizerUnit
	This packetizer generates packets of generic units, representing the number of times an operation cycle has to be repeated by the worker node, e.g. More...
class	TPackMgr
	The PROOF package manager contains tools to manage packages. More...
class	TPerfStats
	Provides the interface for the PROOF internal performance measurement and event tracing. More...
class	TProof
	This class controls a Parallel ROOT Facility, PROOF, cluster. More...
class	TProofDraw
	Implement Tree drawing using PROOF. More...
class	TProofLimitsFinder
	Class to find axis limits and synchronize them between workers. More...
class	TProofLite
	This class starts a PROOF session on the local machine: no daemons, client and master merged, communications via UNIX-like sockets. More...
class	TProofLog
	Implementation of the PROOF session log handler. More...
class	TProofMgr
	The PROOF manager interacts with the PROOF server coordinator to create or destroy a PROOF session, attach to or detach from existing one, and to monitor any client activity on the cluster. More...
class	TProofMgrLite
	Basic TProofMgr functionality implementation in the case of Lite session. More...
class	TProofMonSender
	Provides the interface for PROOF monitoring to different writers. More...
class	TProofMonSenderSQL
	TProofMonSender implementation for the SQL writers. More...
class	TProofNodeInfo
	The purpose of this class is to provide a complete node description for masters, submasters and workers. More...
class	TProofOutputFile
	Class to steer the merging of files produced on the workers. More...
class	TProofOutputList
	Derivation of TList with an overload of ls() and Print() allowing to filter out some of the variables. More...

class	TProofProgressStatus
	Container class for processing statistics. More...
class	TProofQueryResult
	TQueryResult version adapted to PROOF neeeds. More...
class	TProofResourcesStatic

class	TVirtualPacketizer
	The packetizer is a load balancing object created for each query. More...
class	TVirtualProofPlayer
	Abstract interface for the PROOF player. More...
