All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, NotifiableTestStream

public final class TestProvidingInputStream
extends AbstractCommandStream

An InputStream that, when read, provides test class names out of a queue.

The Stream provides only one test at a time, but only after provideNewTest() has been invoked.

After providing each test class name, followed by a newline character, a flush is performed on the FlushReceiver provided by the FlushReceiverProvider that can be set using AbstractForkInputStream.setFlushReceiverProvider(FlushReceiverProvider).

The instance is used only in reusable forks in ForkStarter by one Thread.
