Examples of java.nio.CharBuffer

java.nio.CharBuffer
A buffer of chars.
A char buffer can be created in either of the following ways:
- {@link #allocate(int) Allocate} a new char array and create a bufferbased on it;
- {@link #wrap(char[]) Wrap} an existing char array to create a newbuffer;
- {@link #wrap(CharSequence) Wrap} an existing char sequence to create anew buffer;
- Use {@link java.nio.ByteBuffer#asCharBuffer() ByteBuffer.asCharBuffer}to create a char buffer based on a byte buffer.

    final BufferedReader reader = bufferedReader();
    return new CloseOperation<HttpRequest>(reader, ignoreCloseExceptions) {


      @Override
      public HttpRequest run() throws IOException {
        final CharBuffer buffer = CharBuffer.allocate(bufferSize);
        int read;
        while ((read = reader.read(buffer)) != -1) {
          buffer.rewind();
          appendable.append(buffer, 0, read);
          buffer.rewind();
        }
        return HttpRequest.this;
      }
    }.call();
  }
