Examples of BlockingInputStream

org.exist.storage.io.BlockingInputStream
BlockingInputStream is a combination of an input stream and an output stream, connected through a (circular) buffer in memory. It is intended for coupling producer threads to consumer threads via a (byte) stream. When the buffer is full producer threads will be blocked until the buffer has some free space again. When the buffer is empty the consumer threads will be blocked until some bytes are available again. Closing of the output stream will block until the inputstream is closed. A special version of the close function enables the consumer threads to specify that an exception has occurred. This will cause producer calls to be unblocked and throw an IOException containing this exception as cause. @author Chris Offerman
org.jgroups.util.BlockingInputStream
Bounded input stream. A consumer reads bytes until the end of the stream is reached, or the input stream is closed. The producer writes bytes to the tail and blocks if the capacity has been reached (until the consumer reads more bytes).
This class is for only 1 producer and 1 consumer; multiple producers/consumers will most likely yield incorrect results !
Note that the implementation of this class is optimized for reading and adding a few K at a time; performance will be suboptimal if single bytes are added and read. @author Bela Ban @since 2.12.2
