Class UnboxedHalfDouble

java.lang.Object
  com.sun.electric.database.geometry.btree.unboxed.UnboxedHalfDouble

All Implemented Interfaces:

Unboxed<java.lang.Double>, UnboxedComparable<java.lang.Double>

public class UnboxedHalfDouble
extends java.lang.Object
implements UnboxedComparable<java.lang.Double>

A 64-bit long which is stored internally as a 32-bit float in unboxed form

Field Summary

static UnboxedHalfDouble

instance

Constructor Summary

UnboxedHalfDouble()

Method Summary

int	compare(byte[] buf1, int ofs1, byte[] buf2, int ofs2) Same as Comparable.compare(), but operates directly on serialized representation
java.lang.Double	deserialize(byte[] buf, int ofs) Deserialize a value; need not be compatible with V.readObject()!
float	deserializeFloat(byte[] buf, int ofs)
int	getSize() Return the size, in bytes, of a value; all values must have the same size
void	serialize(java.lang.Double k, byte[] buf, int ofs) Serialize a value; need not be compatible with V.writeObject()!
void	serializeFloat(float f, byte[] buf, int ofs)
