Interface FarragoObjectCache.Entry

All Superinterfaces:

ClosableAllocation, FarragoAllocation

All Known Implementing Classes:

FarragoCacheEntry

Enclosing class:

FarragoObjectCache

public static interface FarragoObjectCache.Entry
extends FarragoAllocation

Interface for a cache entry; same as Map.Entry except that there is no requirement on equals/hashCode. This interface is implemented by FarragoObjectCache; callers are shielded from direct access to the entry representation.

Entry extends FarragoAllocation; its closeAllocation implementation calls FarragoObjectCache.unpin(net.sf.farrago.util.FarragoObjectCache.Entry).
