How to use

getFloat

method

in

org.apache.mina.codec.IoBuffer

/**
 * @see ByteBuffer#getFloat()
 */
public float getFloat() {
  return getFloat(position);
}

/**
 * @see ByteBuffer#getFloat(int)
 */
public float getFloat(int index) {
  return getFloat(getPointerByPosition(index));
}

@Test
public void testFloat() {
  for (ByteOrder bo : new ByteOrder[] { ByteOrder.BIG_ENDIAN, ByteOrder.LITTLE_ENDIAN }) {
    ByteBuffer bb = (ByteBuffer) ByteBuffer.allocate(5).order(bo).putFloat(-0.68f).rewind();
    IoBuffer ioBuffer = IoBuffer.wrap(bb).order(bo);
    assertEquals(5, ioBuffer.capacity());
    ioBuffer.extend(3);
    ioBuffer.position(4);
    assertEquals(8, ioBuffer.capacity());
    ioBuffer.putFloat(3.14f);
    ioBuffer.rewind();
    assertEquals(-0.68f, ioBuffer.getFloat(), 0.001f);
    assertEquals(3.14f, ioBuffer.getFloat(), 0.001f);
    ioBuffer.rewind();
    ioBuffer.putFloat(2, -12.34f);
    assertEquals(-12.34f, ioBuffer.getFloat(2), 0.001f);
  }
}
