                                Design Note
                                ===========

September 2015:

        The C++ library has several types of global constants from different
        classes, such as PropList, PredType, DataSpace, etc...  Previously,
        these global constants were declared statically and the C++ library used
        a constant, called PredType::AtExit, to detect when all the global
        contants are destroyed then close the C library (H5close).  This method
        relied on the order of the constants being created and destroyed and
        that PredType constants be the last to be destroyed.  In September
        2015, it was recognized that the order in which the global constants were
        created and destroyed was actually undefined, thus can be different
        between different compilers.  This resulted in failure when compilers
        destroy PredType constants before others because when PredType::AtExit
        was destroyed, the C library was closed, so when the constants of other
        classes such as PropList or DataSpace were being deleted, the C library
        would not be available.

        These are the classes that have global constants:
                + PredType
                + DataSpace
                + PropList (and its subclasses below)
                + FileAccPropList
                + FileCreatPropList
                + DSetMemXferPropList
                + DSetCreatPropList

        The new method includes these main points:

        - The C++ library uses dynamically allocated constants to have the
          control in which order the global constants are created/destroyed.

        - The previous static constants are changed to be the references to
          the dynamically allocated constants to avoid impact on applications.

        - The first time an IdComponent default constructor is invoked, it
          will call the function H5Library::initH5cpp which registers the
          terminating functions from each class that has the global constants
          so that these functions can destroy those constants at the exit of the
          application.  IdComponent is a baseclass of any object class that has
          an identifier, such as Group, DataSet, DataType,...  The classes which
          have the global constants are all derived from IdComponent.

        - At the normal termination of the application, each registered function
          for each constant type will delete all the allocated constants in
          that type class, then a different terminating function, which was also
          registered with atexit() by initH5cpp, will call H5close to close the
          C library.

        The following list presents the differences between the old and new
        methods and the changes implemented for the new method.

        1.  The following items are added to class H5Library:
                // Private instance to be created by H5Library only
                static H5Library* instance;

                // Returns a singleton H5Library to initialize the global
                // constants, invoked in IdComponent default constructor
                static H5Library* getInstance(); // public

                // Registers cleanup and terminating functions with atexit(),
                // called in IdComponent default constructor
                static void initH5cpp(void); // public

                // Calls H5close to terminate the library, registered with
                // atexit(), as the last thing to be done.
                static void termH5cpp(void); // public

        2.  The following shows the differences between the old and new methods
            for allocating the PredType constants.  There are more than 100
            constants, but only one is shown here for examples.

        Old Method:
        ----------
                // Declaration of the constant - in "H5PredType.h"
                static const PredType NATIVE_INT;

                // Definition of the constant - in "H5PredType.cpp"
                const PredType PredType::NATIVE_INT(H5T_NATIVE_INT);

        New Method:
        ----------
                // Declare pointer for a constant - in "H5PredType.h"
                static PredType* NATIVE_INT_; // "H5PredType.h"

                // Change previous constant to reference - in "H5PredType.h"
                static const PredType& NATIVE_INT;

                // The assignment of the first static constant, named
                // PREDTYPE_CONST, calls makePredTypes() which allocates the
                // dynamic memory for every PredType constant.

                // Creates a dynamic PredType object representing a C constant
                // - in makePredTypes()
                NATIVE_INT_ = new PredType(H5T_NATIVE_INT);

                // Assign the constant reference to the dynamic object
                // - in "H5PredType.cpp"
                const PredType& PredType::NATIVE_INT = *NATIVE_INT_;

            Functions added to class PredType:

                // Creates the constants
                static void makePredTypes(); // private

                // Calls makePredTypes to create the constants and returns
                // the dummy constant PREDTYPE_CONST;
                static PredType* getPredTypes(); // private

                // Deletes the constants
                static void deleteConstants(); // public

        3.  This section shows the differences between the old and new methods
            for allocating the DataSpace constant, DataSpace::ALL.

        Old Method:
        ----------
                // Declaration of the constant - in "H5DataSpace.h"
                static const DataSpace ALL;

                // Definition of the constant - in "H5DataSpace.cpp"
                const DataSpace DataSpace::ALL(H5S_ALL);

        New Method:
        ----------
                // Declare pointer for a constant - in "H5DataSpace.h"
                static DataSpace* ALL_; // "H5DataSpace.h"

                // Change previous constant to reference - in "H5DataSpace.h"
                static const DataSpace& ALL;

                // Creates a dynamic DataSpace object representing the C constant
                // - in "H5DataSpace.cpp"
                ALL_ = new DataSpace(H5S_ALL);

                // Assign the constant reference to the dynamic object
                // - in "H5DataSpace.cpp"
                const DataSpace& DataSpace::ALL = *ALL_;

            Functions added to class DataSpace:

                // Creates the constant
                static DataSpace* getConstant(); // private

                // Deletes the constant
                static void deleteConstants(); // public

        4.  This section shows the differences between the old and new methods
            for allocating the following constants
                - PropList constant, PropList::DEFAULT.
                - DSetCreatPropList constant, DSetCreatPropList::DEFAULT.
                - DSetMemXferPropList constant, DSetMemXferPropList::DEFAULT.
                - FileCreatPropList constant, FileCreatPropList::DEFAULT.
                - FileAccPropList constant, FileAccPropList::DEFAULT.

            For these constants, the library has the same changes, except the
            class names and the HDF5 corresponding constants. Only the items
            of PropList are listed, and "PropList" can be replaced by any of
            DSetCreatPropList, DSetMemXferPropList, FileCreatPropList,
            FileAccPropList for those classes.  The HDF5 C constant "H5P_DEFAULT"
            can be replaced by any of these respectively: H5P_DATASET_CREATE,
            H5P_DATASET_XFER, H5P_FILE_CREATE, and H5P_FILE_ACCESS.

        Old Method:
        ----------
                // Declaration of the constant - in "H5PropList.h"
                static const PropList DEFAULT;

                // Definition of the constant - in "H5PropList.cpp"
                const PropList PropList::DEFAULT(H5P_DEFAULT);

        New Method:
        ----------
                // Declare pointer for a constant - in "H5PropList.h"
                static PropList* DEFAULT_; // "H5PropList.h"

                // Change previous constant to reference - in "H5PropList.h"
                static const PropList& DEFAULT;

                // Creates a dynamic PropList object representing the C constant
                // - in "H5PropList.cpp"
                DEFAULT_ = new PropList(H5P_DEFAULT);

                // Assign the constant reference to the dynamic object
                // - in "H5PropList.cpp"
                const PropList& PropList::DEFAULT = *DEFAULT_;

            Functions added to class PropList:

                // Creates the constant
                static PropList* getConstant(); // private

                // Deletes the constants
                static void deleteConstants(); // public

            The same functions are added to the subclasses of PropList instead of
            using PropList's because of the class types and in favor of clarity.
