HepTuple v1.6 cvs rtag V01-06-00

New Features in release:
Take advantage of ISOcxx portability
Remove contortitions that were there for old gcc.
These had been fouling up NT.
Dependencies:
ZMutility v1.3.7 or higher
Exceptions v1.2.1 or higher
ISOcxx v1.1 or higher
Optional:
• Cernlib library must be linked in for HBOOK
• histo v5_0_3a0 or higher for histoscope
• root v2_23_00 or higher for ROOT
Restrictions:
Bug in HBOOK with regard to columns of doubles in N-tuples (as earlier)
Impractical to do static instantiation of nTuple and histogram objects (as earlier)
HBOOK Columwise Ntuples are restricted to 50 variables.
HBOOK itself does not handle columnwise Ntuples with more than 50 variables in a block. A good workaround is to have multiple blocks; each may have up to 50 variables.

New Features in release:
Split of libHepTuple.a into a generic library (still libHepTuple.a) and an HBook specific directory and library libHBookHepTuple.a
Fix a bug in disableling the versionning in the ROOT filemanager.
Fix a few problem with column arrays of dimension 2 and more in the ROOT filemanager.

It is currently impractical to do static instantiation of nTuple and histogram objects.

HepTuple beta release: v1.5; cvs rtag V01-05-00

New Features in release:
Upgrade the ROOT filemanger to be able to elegantly support branches with TObject. In the case of split it will see it as a block of elementary type. A new column type will also be introduced and support only by the ROOT filemanager that will let the user create Columns of TObjects.
In the ROOT Filemanager add a constructor switch to select whether the object are versioned or not in the file.
The toyz program has been upgraded to work alternatively with HBook and ROOT (with a command line switch)
Fix behavior of ROOT with index arrays
Add '..' as manager-independent way to navigate directories
Insure that when using HBook, the index column is always read back with an index array.
Insure that the HBook limitation to 16 characters for a directory name is gracefully handled.
Change the internal debugging macro TRACE to HEP_DEBUG to avoid conflict with the microsoft libraries.
Gracefully fails when an illegal character is used in a title.
Update for KAI 3.4.

New Features in release:
Minor bugfixes.
Correction of LIBDEPS file.

New Features in release:
Arrays of Histograms.
See the include file HepHist1DArray.h for detailed information.
Implemented the HepNtuple class for the ROOT filemanager.
It is now as the same functionality as the HBook and Histo filemanager. However columns containing TObjects are not yet supported. Aee Warning and Coming soon for ROOT specific information.
Small bug fixes.

Warning:
The ROOT filemanager uses TTree to implement HepNtuple. When reading a file with TTree that has not been created by HepTuple, we currently ignore ALL branches that have been created with a TObject. The only branch creation supported is the TTree::Branch call that take a leaflist as an argument.

3/16/99

HepTuple beta release: v1.4; cvs rtag V01-04-00

New Features in release:
Arithmetic on histograms.
You can now add, multiply and divide any histograms together (independently of their respective managers).
Appending ntuples.
You can append two ntuples with the same layout independently of their respective managers.
Cloning.
You can now duplicate the structure (makeEmpty) or both the structure and the content (makeClone) of any histogram or ntuples, of course independently of their respective managers.
The Root and HBook filemanagers are now fully available on nt.
Read Only Files.
HepTuple can now open (and read contents of) manager files that are protected as Read-only.
All methods which accept char* also now accept string arguments.
Bug fixes related to directory management in HBook

Restrictions:
There is a bug in HBOOK with regard to columns of doubles in N-tuples:
These are NOT portable among platforms with different endian-ness (SGI vs Intel/Dec). This inconvenience will NOT be present with the Histoscope manager.
Warning:
In a future release the HBOOK part of the HepTuple library WILL be separated from the manager independent part. Software using the hbook part of HepTuple will need to add -lHBookHepTuple to their link lines.
Coming soon:
• split of libHepTuple.a in a generic library (still libHepTuple.a) and a HBook specific library libHBookHepTuple.a
• Histogram arrays.
• Ntuples for the Root filemanager.

HepTuple beta release: v1.3; cvs rtag V01-03-00

(Note - actual rtag date for this version was 12/4/98; the release notification was inadvertently forgotten at that time.)
Beta release of full featured Histoscope file manager
Alpha release of minimal feature Root file manager.
The Root file manager currently only supports:
• all directory operations
• reading and writing histograms
  Output of some of the statistics is not yet exactly equivalent to the other managers
• writing very simple ntuples

Restrictions:
There is a bug in HBOOK with regard to columns of doubles in N-tuples:
These are NOT portable among platforms with different endian-ness (SGI vs Intel/Dec). This inconvenience will NOT be present with the Histoscope manager.
Warning:
HBOOK has been compiled and works on NT using Digital Fortran -- using the default calling conventions. DSPACK on NT evidently uses the (different) "unix" calling conventions (with the same compiler). For people using HBOOK via HepTuple, this should be fine. But when linking DSPACK-containing code with direct HBOOK calls, one would need to pay attention to this issue.

8/21/98

HepTuple beta release: v1.2; cvs rtag V01-02-00

HepTuple beta release: v1.1.9; cvs rtag V01-01-09

New Features:
Revised GNUmakefile for toyz
to circumvent KAI problem that was randomly breaking the build.

7/22/98

HepTuple beta release: v1.1.8; cvs rtag V01-01-08

New Features:
Strenghtened the object ownership model.
The HepFileManager is now completly responsible for creating and deleting the object. When the manager is detroyed, it automatically delete all its objects (Histogram, ntuple, etc...). A call to the member function release() for an object, instructs the manager that it can eventually delete the object if it wants to. (i.e the user is finished with this object and does not care what happen to its copy in memory)

Geant3
Fixed bug preventing the use of Geant3 and HepTuple in the same program.

Two HBook file managers.
Fixed bug in HBook and in HepTuple effectively preventing the use of two HBook file manager.

Fixed bug in rmdir
started Babar convergence
prepared for namespace
toyz test now uses PhysicsVector
