Examples of com.sleepycat.je.cleaner.PackedOffsets

com.sleepycat.je.cleaner.PackedOffsets
Stores a sorted list of LSN offsets in a packed short representation. Each stored value is the difference between two consecutive offsets. The stored values are stored as one or more shorts where each short holds 0x7fff values. Shorts are in LSB order. The value is negated if more shorts for the same offset follow; this works because offsets are always positive values.
