Examples of java.io.PipedInputStream.available()

java.io.PipedInputStream.available()
Answers a int representing the number of bytes that are available before this PipedInputStream will block. This method returns the number of bytes written to the pipe but not read yet up to the size of the pipe. @return int the number of bytes available before blocking. @throws IOException If an error occurs in this stream.
