From d8c843156a3879a51f7e3062f51beba4e84b1ca2 Mon Sep 17 00:00:00 2001 From: Barbara Jones Date: Thu, 8 Mar 2001 11:37:14 -0500 Subject: [svn-r3562] Add to tutorial Purpose: [is this a bug fix? feature? ...] Description: [describe the bug, or describe the new feature, etc] Solution: [details about the changes, algorithm, etc...] [Please as detail as you can since your own explanation is better than others guessing it from the code.] Platforms tested: [machines you have tested the changed version. This is absolute important. Test it out on at least two or three different platforms such as Big-endian-32bit (SUN/IRIX), little-endian-32(LINUX) and 64-bit (IRIX64/UNICOS/DEC-ALPHA) would be good.] ---

Some Explanation About Tutorial Examples +

The Java tutorial programs try to stay close to the corresponding C +program. The main function's structure almost same as C program, with one +call for each HDF5 library function. For example, where the C program has +a call to H5Fopen(), the Java program has a call to H5Fopen_wrap(). +

The wrapper functions call the HDF-5 library using the Java HDF-5 Interface +(JHI5). The HDF-5 C interface returns error codes; these are represented +by Java Exceptions in the JHI5. The wrapper function catches the exception +and prints a message. +

For example, the H5Fopen_wrap() method calls the JHI5, and catches +any exceptions which may occur: +

   public static int H5Fopen_wrap (String name, int flags, int access_id)
+   {
+      int file_id = -1;    // file identifier 
+      try 
+      {
+         // Create a new file using default file properties.
+         file_id = H5.H5Fopen (name, flags, access_id);
+      }
+      catch (HDF5Exception hdf5e)
+      {
+         System.out.println 
+             ("DatasetRdWt.H5Fopen_wrap() with HDF5Exception: "
+              + hdf5e.getMessage());
+      }
+      catch (Exception e)
+      {
+         System.out.println 
+             ("DatasetRdWt.H5Fopen_wrap() with other Exception: " 
+              + e.getMessage());
+      }
+      return file_id;
+   }
