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.

    InputStream strm = getClass().getResourceAsStream(ROOT_PATH+path);
    if (strm == null) {
      this.sendErrorPage(ctx, 404, l10n("pathNotFoundTitle"), l10n("pathNotFound"));
      return;
    }
    Bucket data = ctx.getBucketFactory().makeBucket(strm.available());
    OutputStream os = data.getOutputStream();
    try {
    byte[] cbuf = new byte[4096];
    while(true) {
      int r = strm.read(cbuf);
