com.goldencode.p2j.persist.Persistence.QueryKey

Enclosing class:

Persistence

private static class Persistence.QueryKey
extends java.lang.Object

A hash key for a unique combination of FQL, with the existence of lack of maximum results, and starting row offset options. The actual values for paging are not cached, we need to know only the query form and the actual values are filled when object is used.
