org.apache.pig.piggybank.evaluation.decode.BinCond

Syntax:

String BinCond(boolean_expression1, mapping_string1, ..., boolean_expressionN, mapping_stringN, other_string).

Logic:

if (boolean_expression1) return mapping_string1; ...... else if (boolean_expressionN) return mapping_stringN; else return other_string;

        t3.set(3, "a");
        t3.set(4, true);
        t3.set(5, "s");
        t3.set(6, "n");
        
        BinCond func = new BinCond();
        String r = func.exec(t1);
        assertTrue(r.equals("s"));
        r = func.exec(t2);
        assertTrue(r==null);
        try {
            r = func.exec(t3);
            fail("Exception not triggered");
        } catch (IOException e) {
            assertTrue(e.getMessage().equals("BinCond : Encounter null in the input"));
        }
    }
