Examples of javax.sound.sampled.AudioInputStream.available()

javax.sound.sampled.AudioInputStream.available()
Returns the maximum number of bytes that can be read (or skipped over) from this audio input stream without blocking. This limit applies only to the next invocation of a read or skip method for this audio input stream; the limit can vary each time these methods are invoked. Depending on the underlying stream,an IOException may be thrown if this stream is closed. @return the number of bytes that can be read from this audio input stream without blocking @throws IOException if an input or output error occurs @see #read(byte[],int,int) @see #read(byte[]) @see #read() @see #skip
