Examples of com.sleepycat.bind.tuple.StringBinding

com.sleepycat.bind.tuple.StringBinding
A concrete TupleBinding for a simple String value.
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.

        StringBinding.stringToEntry("abc", entry);
  assertEquals(4, entry.getData().length);
        assertEquals("abc", StringBinding.entryToString(entry));


        new StringBinding().objectToEntry("abc", entry);
  assertEquals(4, entry.getData().length);


        StringBinding.stringToEntry(null, entry);
  assertEquals(2, entry.getData().length);
        assertEquals(null, StringBinding.entryToString(entry));
