 package com.sleepycat.bind.tuple;
 
A concrete TupleBinding for a Short primitive wrapper or a short primitive.

There are two ways to use this class:

  1. When using the com.sleepycat.je package directly, the static methods in this class can be used to convert between primitive values and com.sleepycat.je.DatabaseEntry 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.

Converts an entry buffer into a simple short value.

Parameters:
entry is the source entry buffer.
Returns:
the resulting value.
    public static short entryToShort(DatabaseEntry entry) {
        return entryToInput(entry).readShort();
    }

    
Converts a simple short value into an entry buffer.

Parameters:
val is the source value.
entry is the destination entry buffer.
    public static void shortToEntry(short valDatabaseEntry entry) {
        outputToEntry(sizedOutput().writeShort(val), entry);
    }

    
Returns a tuple output object of the exact size needed, to avoid wasting space when a single primitive is output.
    private static TupleOutput sizedOutput() {
        return new TupleOutput(new byte[]);
    }
