Hmm, that's only half the story... Think about this ... 'Create Date' > ($TIMESTAMP$ - (7 * 24 * 60 * 60)) AND <whatever LJ Longwing quoted below>
i.e. qualifiers that involve arithmetic operations as well. The recursiveness/complexity grows even more... :) Unless you're really trying to emulate the qualification evaluation (like AR workflow runtimes such as Server/Midtier/UserTool typically do), I suggest not to go deal with all this complexity yourself. Rather see, if your utility can get by, simply by offering a string representation of the qualifier. To do these, you can surely use ARServerUser.formatQualification/parseQualification etc routines within Java API to convert AR given qualifier object to a readable string format or the reverse. However, if your requirement is to really build the "qualifier tree object" and process it some how - then make sure that your logic indeed covers logical operators (Longwing quoted these below), as well as arithmetic operations and finally deal with field/keyword references appropriately.

A QualifierInfo object has three main parts, LeftOperand, Operation, and RightOperand. To explain these parts I will give you an example ('Status' = "Fixed") AND ('Create Date' < $DATE$) Ok, if that is your QualifierInfo object, here are your pieces LeftOperand = ('Status' = "Fixed") Operation = AND RightOperand = ('Create Date' < $DATE$) So, what I have done in several programs now is to write an iterative subroutine, if you check the operation to determine if it is a relational operation (< > = != etc). If it's not, I throw RightOperand back into the sub till it is, If it is then you know you are down to a single operand, and then you can parse the field/value on left and right for what you want to check/test for. Please let me know if this helps any....it's still a bit fuzzy in my head, but I understand it well enough as it is to do what I need to do. _Platinum Sponsor: [email protected] ARSlist: "Where the Answers Are"_ _______________________________________________________________________________ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org Platinum Sponsor:[email protected] ARSlist: "Where the Answers Are"
