## com.sleepycat.bind
Interface EntityBinding<E>

All Known Implementing Classes:
  SerialSerialBinding, TupleSerialBinding, TupleSerialMarshalledBinding, TupleTupleBinding, TupleTupleMarshalledBinding

    public interface EntityBinding<E>

A binding between a key-value entry pair and an entity object.

WARNING: Binding instances are typically shared by multiple threads and binding methods are called without any special synchronization. Therefore, bindings must be thread safe. In general no shared state should be used and any caching of computed values must be done with proper synchronization.
