Examples of com.sleepycat.bind.tuple.LongBinding

com.sleepycat.bind.tuple.LongBinding
A concrete TupleBinding for a Long primitive wrapper or a long primitive.
There are two ways to use this class:
1. When using the {@link com.sleepycat.je} package directly, the staticmethods in this class can be used to convert between primitive values and {@link DatabaseEntry} objects.
2. When using the {@link com.sleepycat.collections} package, an instance ofthis class can be used with any stored collection. The easiest way to obtain a binding instance is with the {@link TupleBinding#getPrimitiveBinding} method.
