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
