Examples of com.sleepycat.bind.tuple.TupleOutput

com.sleepycat.bind.tuple.TupleOutput
An OutputStream with DataOutput-like methods for writing tuple fields. It is used by TupleBinding.
This class has many methods that have the same signatures as methods in the {@link java.io.DataOutput} interface. The reason this class does notimplement {@link java.io.DataOutput} is because it would break the interfacecontract for those methods because of data format differences.
