Hi folks, I have a class "A" that has as one of its' properties ,"b", a collection of objects (of type "C"). I wish to a) provide a (READ) property in A that returns a subset of the collection (b') based on a parameter (relating to a known property of C, say something like "DaysAgo is less than 45" where DaysAgo is a property of C), and b) copy all attributes of each instance of C in b' onto a new clipboard item.
To confound the issue, the DaysAgo property of C is computed and is relative to another date that is independent of both A and C. Or to put that another way, I suppose I need a window function, rather than a subsetting function that will return each instance of C in b that is between a basedate and a number of days beforehand. To try and put this into a better perspective, we have a patient "Ms Sally Simpson" who was diagnosed in early August as suffering from infectious mononucleosis (aka glandular fever, college disease, kissing disease etc etc). She has had a series of pathology tests done over the last 6 months when she first presented ("Doctor, I dont feel well"). The blood samples take from her over this period may have been subjected to over 150 odd pathology tests. My learned pathological statisticians ( sorry pathology statisticians) now want to select specific examples of certain tests to see if there is any evidence of atypical results being "ahem, missed" in the earlier tests. So, class A(patient) (instance "Simpson, Sally") has a collection b of path tests generalised as a "test" (C) (with many specialisations). The requirement put to me is "I want to copy all the data for the IG Count tests done on Sally in the period between 2 Aug and 45 days prior to the clipboard (so I can paste them into a spreadsheet and do mystical incantations over them)" (OK, I added the last bit.) To me this requires subsetting b over testtype between two parameters (day0 and daysago) So, is there a way to provide a "parameterised" property accessor, TestSeries_Read(ttype as TestTypeCode, startdate as Date, window as Integer) as TestSeries and when I get it, how do I copy all attributes of each instance in the subset to the clipboard (i.e. how can I serialise a specialisation of a generic type). If you have read this far, thank you. If you can provide some help, may you be blessed. -- best regards Bruce Bruen ------------------------------------------------------------------------------ Nokia and AT&T present the 2010 Calling All Innovators-North America contest Create new apps & games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev _______________________________________________ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user
