/**
 * Instances of the class XdrFloat represent (de-)serializeable
 * floats, which are especially useful in cases where a result with only a
 * single float is expected from a remote function call or only a single
 * float parameter needs to be supplied.

Please note that this class is somewhat modelled after Java's primitive * data type wrappers. As for these classes, the XDR data type wrapper classes * follow the concept of values with no identity, so you are not allowed to * change the value after you've created a value object. * * @version $Revision: 1.1 $ $Date: 2003/08/13 12:03:40 $ $State: Exp $ $Locker: $ * @author Harald Albrecht */ public class XdrFloat implements XdrAble { /** * Constructs and initializes a new XdrFloat object. * * @param value Float value. */ public XdrFloat(float value) { this.value = value; } /** * Constructs and initializes a new XdrFloat object. */ public XdrFloat() { this.value = 0; } /** * Returns the value of this XdrFloat object as a float * primitive. * * @return The primitive float value of this object. */ public float floatValue() { return this.value; } /** * Encodes -- that is: serializes -- a XDR float into a XDR stream in * compliance to RFC 1832. * * @throws OncRpcException if an ONC/RPC error occurs. * @throws IOException if an I/O error occurs. */ public void xdrEncode(XdrEncodingStream xdr) throws OncRpcException, IOException { xdr.xdrEncodeFloat(value); } /** * Decodes -- that is: deserializes -- a XDR float from a XDR stream in * compliance to RFC 1832. * * @throws OncRpcException if an ONC/RPC error occurs. * @throws IOException if an I/O error occurs. */ public void xdrDecode(XdrDecodingStream xdr) throws OncRpcException, IOException { value = xdr.xdrDecodeFloat(); } /** * The encapsulated float value itself. */ private float value; } // End of XdrFloat.java
