+ * Reference Manual.

+ * </table>
+ * <b>General Rules for Passing Arguments and Results</b>
+ * <p>
+ * In general, arguments passed <b>IN</b> to Java are the analogous basic types, as above. The exception is for arrays,
+ * which are discussed below.
+ * <p>
+ * The <i>return value</i> of Java methods is also the analogous type, as above. A major exception to that rule is that
+ * all HDF functions that return SUCCEED/FAIL are declared <i>boolean</i> in the Java version, rather than <i>int</i> as
+ * in the C. Functions that return a value or else FAIL are declared the equivalent to the C function. However, in most
+ * cases the Java method will raise an exception instead of returning an error code.
+ * See <a href="#ERRORS">Errors and Exceptions</a> below.
+ * <p>
+ * Java does not support pass by reference of arguments, so arguments that are returned through <b>OUT</b> parameters
+ * must be wrapped in an object or array. The Java API for HDF consistently wraps arguments in arrays.
+ * <p>
+ * For instance, a function that returns two integers is declared:
+ *
+ * <pre>
+ * h_err_t HDF5dummy( int *a1, int *a2)
+ * </pre>
+ *
+ * For the Java interface, this would be declared:
+ *
+ * <pre>
+ * public synchronized static native void HDF5dummy(int args[]);
+ * </pre>
+ *
+ * where <i>a1</i> is <i>args[0]</i> and <i>a2</i> is <i>args[1]</i>, and would be invoked:
+ *
+ * <pre>
+ * H5.HDF5dummy(a);
+ * </pre>
+ *
+ * <p>
+ * All the routines where this convention is used will have specific documentation of the details, given below.
+ * <p>
+ * <b>Arrays</b>
+ * <p>
+ * HDF5 needs to read and write multi-dimensional arrays of any number type (and records). The HDF5 API describes the
+ * layout of the source and destination, and the data for the array passed as a block of bytes, for instance,
+ *
+ * <pre>
+ * herr_t H5Dread(long fid, long filetype, long memtype, long memspace, void *data);
+ * </pre>
+ *
+ * <p>
+ * where ``void *'' means that the data may be any valid numeric type, and is a contiguous block of bytes that is the
+ * data for a multi-dimensional array. The other parameters describe the dimensions, rank, and datatype of the array on
+ * disk (source) and in memory (destination).
+ * <p>
+ * For Java, this ``ANY'' is a problem, as the type of data must always be declared. Furthermore, multidimensional
+ * arrays are definitely <i>not</i> layed out contiguously in memory. It would be infeasible to declare a separate
+ * routine for every combination of number type and dimensionality. For that reason, the
+ * <a href="./hdf.hdf5lib.HDFArray.html"><b>HDFArray</b></a> class is used to discover the type, shape, and size of the
+ * data array at run time, and to convert to and from a contiguous array of bytes in synchronized static native C order.
+ * <p>
+ * The upshot is that any Java array of numbers (either primitive or sub-classes of type <b>Number</b>) can be passed as
+ * an ``Object'', and the Java API will translate to and from the appropriate packed array of bytes needed by the C
+ * library. So the function above would be declared:
+ *
+ * <pre>
+ * public synchronized static native int H5Dread(long fid, long filetype, long memtype, long memspace, Object data);
+ * </pre>
+ * OPEN_IDS.addElement(id);
+
+ * and the parameter <i>data</i> can be any multi-dimensional array of numbers, such as float[][], or int[][][], or
+ * Double[][].
+ * <p>
+ * <b>HDF-5 Constants</b>
+ * <p>
+ * The HDF-5 API defines a set of constants and enumerated values. Most of these values are available to Java programs
+ * via the class <a href="./hdf.hdf5lib.HDF5Constants.html"> <b>HDF5Constants</b></a>. For example, the parameters for
+ * the h5open() call include two numeric values, <b><i>HDFConstants.H5F_ACC_RDWR</i></b> and
+ * <b><i>HDF5Constants.H5P_DEFAULT</i></b>. As would be expected, these numbers correspond to the C constants
+ * <b><i>H5F_ACC_RDWR</i></b> and <b><i>H5P_DEFAULT</i></b>.
+ * <p>
+ * The HDF-5 API defines a set of values that describe number types and sizes, such as "H5T_NATIVE_INT" and "hsize_t".
+ * These values are determined at run time by the HDF-5 C library. To support these parameters, the Java class
+ * <a href="./hdf.hdf5lib.HDF5CDataTypes.html"> <b>HDF5CDataTypes</b></a> looks up the values when initiated. The values
+ * can be accessed as public variables of the Java class, such as:
+ *
+ * <pre>
+ * long data_type = HDF5CDataTypes.JH5T_NATIVE_INT;
+ * </pre>
+ *
+ * The Java application uses both types of constants the same way, the only difference is that the
+ * <b><i>HDF5CDataTypes</i></b> may have different values on different platforms.
+ * <p>
+ * <b>Error handling and Exceptions</b>
+ * <p>
+ * The HDF5 error API (H5E) manages the behavior of the error stack in the HDF-5 library. This API is available from the
+ * JHI5. Errors are converted into Java exceptions. This is totally different from the C interface, but is very natural
+ * for Java programming.
+ * <p>
+ * The exceptions of the JHI5 are organized as sub-classes of the class
+ * <a href="./hdf.hdf5lib.exceptions.HDF5Exception.html"> <b>HDF5Exception</b></a>. There are two subclasses of
+ * <b>HDF5Exception</b>, <a href="./hdf.hdf5lib.exceptions.HDF5LibraryException.html"> <b>HDF5LibraryException</b></a>
+ * and <a href="./hdf.hdf5lib.exceptions.HDF5JavaException.html"> <b>HDF5JavaException</b></a>. The sub-classes of the
+ * former represent errors from the HDF-5 C library, while sub-classes of the latter represent errors in the JHI5
+ * wrapper and support code.
+ * <p>
+ * The super-class <b><i>HDF5LibraryException</i></b> implements the method '<b><i>printStackTrace()</i></b>', which
+ * prints out the HDF-5 error stack, as described in the HDF-5 C API <i><b>H5Eprint()</b>.</i> This may be used by Java
+ * exception handlers to print out the HDF-5 error stack.
