Class H5

    java.lang.Object
      ncsa.hdf.hdf5lib.H5

All Implemented Interfaces:
  java.io.Serializable

    public class H5

extends java.lang.Object
implements java.io.Serializable

This class is the Java interface for the HDF5 library.

This code is the called by Java programs to access the entry points of the HDF5 library. Each routine wraps a single HDF5 entry point, generally with the arguments and return codes analogous to the C interface.

For details of the HDF5 library, see the HDF5 Documentation at: http://hdfgroup.org/HDF5/

Mapping of arguments for Java

In general, arguments to the HDF Java API are straightforward translations from the 'C' API described in the HDF Reference Manual.

HDF-5 C types to Java types
HDF-5 | Java
H5T_NATIVE_INT | int, Integer
H5T_NATIVE_SHORT | short, Short
H5T_NATIVE_FLOAT | float, Float
H5T_NATIVE_DOUBLE | double, Double
H5T_NATIVE_CHAR | byte, Byte
H5T_C_S1 | java.lang.String
void * (i.e., pointer to `Any') | Special -- see HDFArray

General Rules for Passing Arguments and Results

In general, arguments passed IN to Java are the analogous basic types, as above. The exception is for arrays, which are discussed below.

The return value 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 boolean in the Java version, rather than int 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 Errors and Exceptions below.

Java does not support pass by reference of arguments, so arguments that are returned through OUT parameters must be wrapped in an object or array. The Java API for HDF consistently wraps arguments in arrays.

For instance, a function that returns two integers is declared:

           h_err_t HDF5dummy( int *a1, int *a2)

For the Java interface, this would be declared:

     public synchronized static native int HDF5dummy(int args[]);

where a1 is args[0] and a2 is args[1], and would be invoked:

     H5.HDF5dummy(a);

All the routines where this convention is used will have specific documentation of the details, given below.

Arrays

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,

          herr_t H5Dread(int fid, int filetype, int memtype, int memspace,
          void * data);

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).

For Java, this ``ANY'' is a problem, as the type of data must always be declared. Furthermore, multidimensional arrays are definitely not 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 HDFArray 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.

The upshot is that any Java array of numbers (either primitive or sub-classes of type Number) 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:

     public synchronized static native int H5Dread(int fid, int filetype,
             int memtype, int memspace, Object data);

and the parameter data can be any multi-dimensional array of numbers, such as float[][], or int[][][], or Double[][].

HDF-5 Constants

The HDF-5 API defines a set of constants and enumerated values. Most of these values are available to Java programs via the class HDF5Constants. For example, the parameters for the h5open() call include two numeric values, HDFConstants.H5F_ACC_RDWR and HDF5Constants.H5P_DEFAULT. As would be expected, these numbers correspond to the C constants H5F_ACC_RDWR and H5P_DEFAULT.

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 HDF5CDataTypes looks up the values when initiated. The values can be accessed as public variables of the Java class, such as:

     int data_type = HDF5CDataTypes.JH5T_NATIVE_INT;

The Java application uses both types of constants the same way, the only difference is that the HDF5CDataTypes may have different values on different platforms.

Error handling and Exceptions

The HDF5 error API (H5E) manages the behavior of the error stack in the HDF-5 library. This API is omitted from the JHI5. Errors are converted into Java exceptions. This is totally different from the C interface, but is very natural for Java programming.

The exceptions of the JHI5 are organized as sub-classes of the class HDF5Exception. There are two subclasses of HDF5Exception, HDF5LibraryException and HDF5JavaException. 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.

The super-class HDF5LibraryException implements the method 'printStackTrace()', which prints out the HDF-5 error stack, as described in the HDF-5 C API H5Eprint(). This may be used by Java exception handlers to print out the HDF-5 error stack.

                                          java.lang.IllegalArgumentException

  H5Pset_buffer sets type conversion and background buffers. status to TRUE or FALSE. Given a dataset transfer property list, H5Pset_buffer sets the maximum size for the type conversion buffer and background buffer and optionally supplies pointers to application-allocated buffers. If the buffer size is smaller than the entire amount of data being transferred between the application and the file, and a type conversion buffer or background buffer is required, then strip mining will be used. Note that there are minimum size requirements for the buffer. Strip mining can only break the data up along the first dimension, so the buffer must be large enough to accommodate a complete slice that encompasses all of the remaining dimensions. For example, when strip mining a 100x200x300 hyperslab of a simple data space, the buffer must be large enough to hold 1x200x300 data elements. When strip mining a 100x200x300x150 hyperslab of a simple data space, the buffer must be large enough to hold 1x200x300x150 data elements. If tconv and/or bkg are null pointers, then buffers will be allocated and freed during the data transfer.

  Parameters:
    `plist` - Identifier for the dataset transfer property list.
    `size` - Size, in bytes, of the type conversion and background buffers.
    `tconv` - byte array of application-allocated type conversion buffer.
    `bkg` - byte array of application-allocated background buffer.
  Throws:
    `HDF5LibraryException` - - Error from the HDF-5 Library.
    `java.lang.IllegalArgumentException` - - plist is invalid.

  Deprecated. As of HDF5 1.8, replaced by `#H5Pget_filter_by_id(int, int, int[], int[], int[], int, String[], int[])`

  H5Pget_filter_by_id returns information about the filter specified in filter_id, a filter identifier. plist_id must be a dataset or group creation property list and filter_id must be in the associated filter pipeline. The filter_id and flags parameters are used in the same manner as described in the discussion of H5Pset_filter. Aside from the fact that they are used for output, the parameters cd_nelmts and cd_values[] are used in the same manner as described in the discussion of H5Pset_filter. On input, the cd_nelmts parameter indicates the number of entries in the cd_values[] array allocated by the calling program; on exit it contains the number of values defined by the filter. On input, the namelen parameter indicates the number of characters allocated for the filter name by the calling program in the array name[]. On exit name[] contains the name of the filter with one character of the name in each element of the array. If the filter specified in filter_id is not set for the property list, an error will be returned and H5Pget_filter_by_id1 will fail.

  Parameters:
    `plist_id` - IN: Property list identifier.
    `filter_id` - IN: Filter identifier.
    `flags` - OUT: Bit vector specifying certain general properties of the filter.
    `cd_nelmts` - IN/OUT: Number of elements in cd_values
    `cd_values` - OUT: Auxiliary data for the filter.
    `namelen` - IN: Anticipated number of characters in name.
    `name` - OUT: Name of the filter.
  Returns:
    the filter identification number if successful. Otherwise returns H5Z_FILTER_ERROR (-1).
  Throws:
    `java.lang.ArrayIndexOutOfBoundsException` - Fatal error on Copyback
    `java.lang.ArrayStoreException` - Fatal error on Copyback
    `java.lang.NullPointerException` - - name or an array is null.
