Re: [rules-dev] Decision table - Otherwise

on a related note I do plan to add OTHERWISE support at a DRL level, just no time to do it right now. Once it's supported at a DRL level, you won't need to as much work on figuring out the inverse options etc. Mark On 31/03/2011 20:25, Michael Anstis wrote: Hi, I'm adding support for "otherwise" to (for the time being) the guided decision table in Guvnor. The idea being if you set a cell to represent "otherwise" the generated rule is the opposite of the accumulation of the other cells; perhaps best explained with an example:- Person( name == ) Mark Kris Geoffrey <otherwise> This would generate:- Person(name not in ("Mark", "Kris", "Geoffrey") Equals is the simple example, this is my thoughts for the other operators we might like to support:- - != becomes "in (<list of the other cells' values)" - < becomes ">= the maximum value of the other cells' values For example:- Person ( age < ) 10 20 30 <otherwise> Person ( age >= 30 ) - <= becomes "> the maximum value of the other cells' values - > becomes "<= the minimum value of the other cells' values - >= becomes "< the minimum value of the other cells' values - "in" becomes "not in (<a list of all values contained in all the other cells' lists of values>)" For example:- Person ( name in ) Jim, Jack Lisa, Jane, Paul <otherwise> Person ( name not in ("Jim", "Jack", "Lisa", "Jane", "Paul" ) ) - I'm not sure there is a simple solution for "matches" and "soundslike" but welcome advice, although a possibility might be to create a compound field constraint:- Person ( name soundslike ) Fred Phil not Person ( name soundslike "Fred" || soundslike "Phil" ) Would this be considered the most suitable approach? Inputs and thoughts welcome.
