[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
