the class ArrayIndexFunction method evaluate.

@Override

    Expression indexExpr = children.get(1);
    if (!indexExpr.evaluate(tuple, ptr)) {
        return false;
    } else if (ptr.getLength() == 0) {
        return true;
    }
    // Use Codec to prevent Integer object allocation
    int index = PInteger.INSTANCE.getCodec().decodeInt(ptr, indexExpr.getSortOrder());
    if (index < 0) {
        throw new ParseException("Index cannot be negative :" + index);
    }
    Expression arrayExpr = children.get(0);
    return PArrayDataTypeDecoder.positionAtArrayElement(tuple, ptr, index, arrayExpr, getDataType(), getMaxLength());
