org.apache.commons.transaction.locking.ReadWriteLock

Conveience implementation of a read/write lock based on {@link GenericLock}.

Reads are shared which means there can be any number of concurrent read accesses allowed by this lock. Writes are exclusive. This means when there is a write access no other access neither read nor write are allowed by this lock.

Calls to both {@link #acquireRead(Object,long)}and {@link #acquireWrite(Object,long)}are blocking and reentrant. Blocking means they will wait if they can not acquire the descired access, reentrant means that a lock request by a specific owner will always be compatible with other accesses on this lock by the same owner. E.g. if you already have a lock for writing and you try to acquire write access again you will not be blocked by this first lock, while others of course will be. This is the natural way you already know from Java monitors and synchronized blocks. @version $Revision: 1.1 $ @see GenericLock
