Examples of wwLock()

com.persistit.TransactionStatus.wwLock()

Acquire a permit on this TransactionStatus. This supports the {@link TransactionIndex#wwDependency(long,long,long)} method. Thepermit is acquired when the transaction is registered (see {@link TransactionIndex#registerTransaction(Transaction)} and releasedonce the transaction is either committed or aborted.

The wwDependency method also attempts to acquire, and then immediately release this permit. This stalls the thread calling wwDependency until the commit/abort status of the current transaction is known. @param timeout @return @throws InterruptedException
