 package com.sleepycat.bind.tuple;
A concrete TupleBinding for an unsorted Float primitive wrapper or an unsorted float primitive.

There are two ways to use this class:

  1. When using the package directly, the static methods in this class can be used to convert between primitive values and objects.
  2. When using the com.sleepycat.collections package, an instance of this class can be used with any stored collection. The easiest way to obtain a binding instance is with the TupleBinding.getPrimitiveBinding(java.lang.Class) method.
