Typically, the container begins a transaction immediately before an enterprise bean method starts and commits the transaction just before the method exits. Each method can be associated with a single transaction. Nested or multiple transactions are not allowed within a method.Container-managed ...
This method does not block. An invocation always returns immediately, either having acquired a lock on the requested region or having failed to do so. If it fails to acquire a lock because an overlapping lock is held by another program then it returnsnull. If it fails to acquire a lock ...

Because all the sound data is loaded in advance, playback can start immediately—for example, as soon as the user clicks a Start button. This can be an advantage compared to the buffered model, where the playback has to wait for the first buffer to fill. In addition, the in-memory, ...
When this action creates an alarm, the alarm state is immediately set to INSUFFICIENT_DATA. The alarm is then evaluated and its state is set appropriately. Any actions associated with the new state are then executed. When you update an existing alarm, its state is left unchanged, ...
Where an I/O operation completes immediately, and the initiating thread is itself a thread in the thread pool, then the completion handler may be invoked directly by the initiating thread. When an AsynchronousFileChannel is created without specifying a thread pool then the channel is associated ...

If such an exception is thrown, it is captured and then thrown again immediately, so as to delegate the remaining work to the finally block. Entering the finally block, the reference to the primary exception is checked. If an exception was thrown, the exception that the close() method may...
You then immediately invoke a method on that object, which returns yet another object, and so on. Many of the I/O examples use the following technique: String value = Charset.defaultCharset().decode(buf).toString(); UserPrincipal group = file.getFileSystem().getUserPrincipalLookupService()....
Both thereadandwritemethodsblockuntil the byte is actually read or written. This means that if the input stream cannot immediately be accessed (usually because of a busy network connection), the current thread blocks. This gives other threads the chance to do useful work while the method is wait...
