Examples of com.sleepycat.bind.EntryBinding

com.sleepycat.bind.EntryBinding
A binding between a key or data entry and a key or data 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.
