Java IO: PipedOutputStream
Jakob Jenkov |
The PipedOutputStream class makes it possible to write to a Java pipe as a stream of bytes.
Pipes are communication between threads running in the same JVM.
PipedOutputStream Example
Here is a simple PipedOutputStream example:
OutputStream output = new PipedOutputStream(pipedInputStream);
while(moreData) {
int data = getMoreData();
output.write(data);
}
output.close();
Note: The proper exception handling has been skipped here for the sake of clarity. To learn more about correct exception handling, go to Java IO Exception Handling.
The write() method of a PipedOutputStream takes an int which contains the byte value of the
byte to write.
More PipedOutputStream Methods
Since PipedOutputStream is a subclass of OutputStream, PipedOutputStream has
the same basic methods and use patterns as an OutputStream. See my OutputStream tutorial
for more information.
Java IO Pipes
The PipedOutputStream must always be connected to a PipedInputStream. When connected
like that, they form a Java pipe. To learn more about Java pipes, go to Java IO: Pipes.
