Examples of com.sleepycat.bind.tuple.TupleInput

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