Class BitMaskTransformer

java.lang.Object

com.neurosys.etl.common.transformers.BitMaskTransformer

public class BitMaskTransformer
extends Object

If a a Number is represented as a sequence of bits. Example: 101111001
Then each bit can represent a flag (boolean state).

Based on the state this transformer will extract the boolean state for a given input number with the mask set or set the bit flag.
