net.sf.basedb.util.StaticCache.LockSafeInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

Enclosing class:

StaticCache

static class StaticCache.LockSafeInputStream
extends FilterInputStream

A lock-safe input stream that releases the associated read lock when the stream is closed.

NOTE! It is important that we keep a strong reference to the 'key' in this class until the stream is closed, since otherwise the locked entry may be reclaimed by the garbage collector.
