Nested Class Summary

Nested Classes

Modifier and Type	Interface and Description
static class	Lazy.Checker.Default This implementation uses two dimensions to evaluate if a lazy reference will be cleared: - time: a ref's "age" in terms of Lazy.lastTouched() compared to System.currentTimeMillis() - memory: the amount of used memory compared to the permitted quota of total available memory.
static interface	Lazy.Checker.Defaults
