Examples of com.sleepycat.je.tree.Key

com.sleepycat.je.tree.Key
Key represents a JE B-Tree Key. Keys are immutable. Within JE, keys are usually represented as byte arrays rather than as Key instances in order to reduce the in-memory footprint. The static methods of this class are used to operate on the byte arrays. One exception is when keys are held within a collection. In that case, Key objects are instantiated so that keys are hashed and compared by value.
