Interface Summary

Interface	Description
BitmapSerdeFactory

Indexed<T>
IndexedDoubles
IndexedFloats	Get a float at an index (array or list lookup abstraction without boxing).
IndexedInts	Get a int an index (array or list lookup abstraction without boxing).
IndexedIntsWriter
IndexedLongs	Get a long at an index (array or list lookup abstraction without boxing).

LongSupplierSerializer
ObjectStrategy<T>
ReadableOffset	A ReadableOffset is an object that provides an integer offset, ostensibly as an index into an array.
