All Implemented Interfaces:

DataOutput, XDRDataOutput

public class XDROutputStream

extends DataOutputStream

implements XDRDataOutput

A class for writing XDR files. Not too hard to do in Java since the XDR format is very similar to the Java native DataStream format, except for String and the fact that elements (ro an array of elements) are always padded to a multiple of 4 bytes. This class requires the user to call the pad method, to skip to the next 4-byte boundary after writing an element or array of elements that may not span a multiple of 4 bytes.
