All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<BlueKey>, BlueKey

public final class IntegerKey
extends ValueKey

A key that can be mapped to a value in a BlueCollection or BlueIndex. Values inserted with this key will be ordered and will fill up an entire segment before creating a new one. I-node usage will grow as new segments are needed.
