compareTwoValues

protected boolean compareTwoValues(java.lang.String valueDataSet1,
                                   java.lang.String unitDataSet1,
                                   java.lang.String valueDataSet2,
                                   java.lang.String unitDataSet2)

In Maximo Classification Spec attributes we support two types of data ALN and NUMERIC. While on deployed site use can select any column type like BigInt, Decimal, etc. Therefore we try to convert both values to int and compare; if any of the conversion fails, tries to convert to double and compare; if conversion fails again on any value, compares lexicographically

If there is no unit on the deployed side, only values are compared If there is a unit on the deployed side, the units must be literally the same, taking into account the task case sensitiveness

Parameters:

valueAuthorized - String representation of the authorized value

unitAuthorized - String representation of the authorized measurement unit

valueDeployed - String representation of the deployed value

unitDeployed - String representation of the deployed measurement unit

Returns:

true if values and units are equal
