Returns the int array which this buffer is based on, if there is one.

Usage

From source file:Main.java

public static void main(String[] args) {
    IntBuffer intBuffer = IntBuffer.allocate(10);
    intBuffer.put(100);//from w  ww.  j  a v  a  2  s.  c om

    intBuffer.rewind();

    IntBuffer intBuffer2 = intBuffer.asReadOnlyBuffer();

    System.out.println(Arrays.toString(intBuffer2.array()));

}
