record

So have gotten to record in my F# journey and at first they seem rather dangerous. At first this seemed clever: type Card = { Name : string; Phone : string; Ok : bool } let cardA = { Name = "Alf" ; Phone = "(206) 555-0157" ; Ok = false } The idea that the cardA is patten matched with Card. Not to mention the simplified pattern matching here: let withTrueOk = list |> Seq.filter (function | { Ok = true} -> true | _ -> false ) Problem is: type Card = { Name : string; Phone : string; Ok : bool } type CardTwo = { Name : string; Phone : string; Ok : bool } let cardA = { Name = "Alf" ; Phone = "(206)

Here I have a tricky situation, I guess. I need to be able to free an object which is a field of a record. I would normally write the cleanup code in the destructor, if it was a class. But since record types can't introduce a "destructor", how would it be possible to call TObject(Field).Free; ? There'll be two types of usage I predict: Replacing the record with a new one. I think this usage would be easy to implement. Since records are value types and so they are copied on assignment, I can overload the assigning operator and free the objects owned by old record. ( Edit: Assignment overloading

I'm trying to create a new record of Person thru my App. I have the name, email and phone nr. How can i pass them to the modal view of newPerson? I'm following Apple's docs, but i'm stuck. I'm using a ABNewPersonViewController. Is that correct? How do I fill the fields in the modal view? Thanks, RL Jason Coco If you want to display something in the ABNewPersonViewController, you have to create and set up an ABRecordRef for the properties you want to pre-fill and then set the displayedPerson property on ABNewPersonViewController. So a simple example may be: - (void)createNewPerson { // Create

I'm hoping someone out there can back me up on this... I've been working on an application that allows the end user to record a small audio file for later playback and am in the process of testing for memory leaks. I continue to very consistently run into a memory leak when the AVAudioRecorder's "stop" method attempts to close the audio file to which it's been recording. This really seems to be a leak in the framework itself, but if I'm being a bonehead you can tell me. To illustrate, I've worked up a stripped down test app that does nothing but start/stop a recording w/ the press of a button.

I am trying to do some simple direct linkage with the library('RecordLinkage') . So I only have one vector tv3 = c("TOURDEFRANCE", 'TOURDEFRANCE', "TOURDE FRANCE", "TOURDE FRANZ", "GET FRESH") The function that I need is compare.dedup of the library('RecordLinkage') and I get : compare.dedup(as.data.frame(tv3))$pairs $pairs id1 id2 tv3 is_match 1 1 2 1 NA 2 1 3 0 NA 3 1 4 0 NA 4 1 5 0 NA 5 2 3 0 NA .... I have trouble finding documentation for the next step. How do I then compare and find my similar pair ? So I found the distance jarowinkler() but it returns only pairs. Basically, you can only

The documentation on documents seems to favor the term "document", and also refers to "database records". Elsewhere, competent MongoDB developers have apparently interchangeably used " attributes " and " records ". What is the correct/official terminology to use in various instances? Is it documented somewhere on mongodb.org? The confusion is merely because many MongoDB users are not just MongoDB users but also use 100 other techs including SQL. I personally have mixed up my language as well, it's not uncommon however document and database records are the same thing and properties, attributes

I have two data types, which are used for hastache templates. It makes sense in my code to have two different types, both with a field named "name". This, of course, causes a conflict. It seems that there's a mechanism to disambiguate any calls to "name", but the actual definition causes problems. Is there any workaround, say letting the record field name be qualified? data DeviceArray = DeviceArray { name :: String, bytes :: Int } deriving (Eq, Show, Data, Typeable) data TemplateParams = TemplateParams { arrays :: [DeviceArray], input :: DeviceArray } deriving (Eq, Show, Data, Typeable) data
