Examples with BitArray com.google.zxing.common.BitArray used on opensource projects

Example 41 with BitArray

use of com.google.zxing.common.BitArray in project zxing by zxing.

the class BitVectorTestCase method testNumBytes.

@Test
public void testNumBytes() {
    BitArray v = new BitArray();
    assertEquals(0, v.getSizeInBytes());
    v.appendBit(false);
    // 1 bit was added in the vector, so 1 byte should be consumed.
    assertEquals(1, v.getSizeInBytes());
    v.appendBits(0, 7);
    assertEquals(1, v.getSizeInBytes());
    v.appendBits(0, 8);
    assertEquals(2, v.getSizeInBytes());
    v.appendBits(0, 1);
    // We now have 17 bits, so 3 bytes should be consumed.
    assertEquals(3, v.getSizeInBytes());
}
