![]() Var attempt3() As Class1 = Class1IsAFuckingArray(mySet.PreservedKeyOrder()) // Nope. Var attempt2() As Class1 = Class1(mySet.PreservedKeyOrder()) // Nope. Var attempt1() As Class1 = mySet.PreservedKeyOrder() // Nope. Something like: Var mySet As OrderedDictionary = New OrderedDictionary There’s no way to force the Xojo compiler to accept that the returned array is of type Class1. (Board president), chief minister under Xunzong, candid remonstrator, author of the Wenzong shilu Xojo (Veritable record of Wenzong) (JTS 176 XTS 97). Whilst it is possible to get back the array used in suggestion, it will be of type Variant, not type Class1. This lets you get back an array of Class1 objects like so: Class1 myArray = mySet.toArray() For instance, you can specify that it only stores elements of Class1: LinkedHashSet mySet = new LinkedHashSet() Amongst other properties, a LinkedHashSet preserves the order of elements added (like the example given above by One thing Java lets you do is declare the type of the LinkedHashSet. One thing this port has taught me (aside from how much more feature-rich Java’s standard library is compared to Xojo’s) is that I really really wish Xojo had better support for generics.įor example, the code I’m porting uses a LinkedHashSet. This code is completely untested, but should get you on the right track (if I understood things You are indeed Works like a charm. You could then loop through the list of keys returned by PreservedKeyList to retrieve the items in the order they were added. ![]() Private Property mPreservedKeyOrder() as Variant For example, we can overload the operators. We have seen in other posts that some of these overloaded methods can be Class Constructors, but, there are others things you can do. ![]() do not replace existing values, as mentioned. Xojo is an Object Oriented Programming Language and, among other things, that means that it supports Methods Overloading. Using Xojo.Core Dim dateA As date New Date (2017,10,23, TimeZone.current) Dim dateB As date New Date (2017,11,23, TimeZone. Sub Value(key as Variant, Assigns data as Variant) Sub Constructor(ParamArray entries as Pair)įunction PreservedKeyOrder() as Variant()ĭim index as Integer = (key) But can’t you just create a subclass of Dictionary and override methods as needed? Class OrderedDictionary ![]() I don’t really understand why the order of items needs to be preserved, so my answer may be a little off. ![]()
