* This module contains the implementation of all the native methods
* used for number conversion. This is represented by the Java
* class HDFNativeData.
*
* These routines convert one dimensional arrays of bytes into
* one-D arrays of other types (int, float, etc) and vice versa.
*
* These routines are called from the Java parts of the Java-C
* interface.
*
* ***Important notes:
*
* 1. These routines are designed to be portable--they use the
* C compiler to do the required native data manipulation.
* 2. These routines copy the data at least once -- a serious
* but unavoidable performance hit.
