Condition

A class modelling the possible conditions used by both transformations and load rules to determine whether or not to execute.

If the variable to access resides in a sub-object, then use the path variable to extract the value from the appropriate location.

Although Condition instances can be made manually, there are many helper functions to make creations more straightforward and easy to read.

With the exception of isDefined/isNotDefined which explicitly check for the existence of values at given keys, Operators are typically expected to

• throw MissingDataItemException if the data item is not found in the payload

• throw MissingFilterException if the filter is null

• throw NumberParseException if it requires a numeric value in the payload or filter, but they were not parseable as such

• throw UnsupportedOperatorException if the operator is not supported for the type of data found in the payload
