[svn-r2897] Purpose:
C++ API for 1.3.x branch
Description:
The *.C and *.h files named different than those in 1.2.x.
They are in the form: 'H5' + classname, or just classname if
the classname is already prefixed with 'H5' to avoid ambiguity
in documentation context. This version has several hidden bugs
fixed and an improvement on the reference counting approach.
The classes and their inheritance structure are listed below:
---------------------------------------
H5Library
Exception
RefCounter
IdComponent
H5File
DataSpace
H5Object
Group
AbstractDs
DataSet
Attribute
DataType
PredType
EnumType
CompType
AtomType
StrType
IntType
FloatType
PropList
FileCreatPropList
FileAccPropList
DSetCreatPropList
DSetMemXferPropList
---------------------------------------
IdComponent uses RefCounter to keep track of opened objects
so proper termination of HDF5 objects can be maintained.
Each class has a .h file containing the class declaration and
a .C file containing its definition. In addition to the classes
files, the following files do not have class information:
- H5Cpp.h: header file to be included in user's application
- H5Idtemplates.h: contains a template function used by several classes
- H5Classes.h: contains forward class declarations
- H5CommonFG.*: contains common code used by classes H5File and Group
- H5Include.h: contains the hdf5.h header file and the #undef RCSID
to work around the problem: multiple defined RcsId
- H5Alltypes.h: simply serves as a container to hold the header
files of all datatypes to simplify the header file inclusion
Platforms:
Solaris (arabica) and Linux
