Detailed Description

This specialization of DMR is used to manage the 'resource' of the open HDF4 file handle so that the BES will close that handle once the framework is done working with the file. This provides a way for the code in HDF4RequestHandler.cc to read data of HDF4 and HDF-EOS2 objects. when HDF4/HDF-EOS2 file IDs are opened to fetch information to build DDS and DAS, these file IDs are kept to access data. In this way, multiple file open/close calls can be reduced to speed up the access performance. This works well when using file netCDF module with an HDF-EOS2 or HDF4 file that have many variables. When the DMR is deleted by the BES, the HDF4DMR() destructor closes the file.
