Examples of java.io.InputStream.available()

java.io.InputStream.available()
Answers a int representing then number of bytes that are available before this InputStream will block. This method always returns 0. Subclasses should override and indicate the correct number of bytes available. @return the number of bytes available before blocking. @throws IOException If an error occurs in this InputStream.
