What is the best way to check if a given object is of a given type. How about checking if the object inherits from a given type. Let's say I have an object o. How do I check if it's an str? ...
Java & Oracle both have a timestamp type called Date. Developers tend to manipulate these as if they were calendar dates, which I've seen cause nasty one-off bugs. For a basic date quantity you can simply chop off the time portion upon input, i.e., reduce the precision. But if you do that with a date range, (e.g.: 9/29-9/30), the diffe...
Hi All, I'm using CodeSynthesis XSD C++/Tree Mapping utility to convert an existing xsd into c++ code we can populate the values in. This was we always make sure we follow the schema. After doing the conversion, I'm trying to get it to work so I can test it. Problem is, I'm not used to doing this in c++ and it's my first time with thi...
I would like to use VB9 but am not sure what syntax to use to say that I want a variable to be statically typed as in C#'s: var foo = new Whatever(); In previous versions of VB: Dim foo = New Whatever() created a dynamically typed variable. Is there a way to get static typing without actually writing the type in VB9? ...
Suppose I have a base class B, and a derived class D. I wish to have a method foo() within my base class that returns a new object of whatever type the instance is. So, for example, if I call B.foo() it returns an object of type B, while if I call D.foo() it returns an object of type D; meanwhile, the implementation resides solely in t...
I want to get a System.Type given only the type name in a string. For instance, if I have an object: MyClass abc = new MyClass(); I can then say: System.Type type = abc.GetType(); But what if all I have is: string className = "MyClass"; ...
I need to make some reflective method calls in Java. Those calls will include methods that have arguments that are primitive types (int, double, etc.). The way to specify such types when looking up the method reflectively is int.class, double.class, etc. The challenge is that I am accepting input from an outside source that will specify...
What data structure does the following declaration specify? List<ArrayList>[] myArray; I think it should declare an array where each element is a List (e.g., a LinkedList or an ArrayList) and require that each List contain ArrayList objects. My reasoning: List<String> someList; // A List of String objects List<ArrayLi...
In Scala, is it possible to get the string representation of a type at runtime? I am trying to do something along these lines: def printTheNameOfThisType[T]() = { println(T.toString) } ...
I have a Windows forms project and a Web Service project in my solution, and I'm trying to call the web service and return a customer object as the result. The problem is that when I try to receive the return object, I get an error that it can't convert it. For example, here is the signature for my webservice: Public Function GetDriverB...
I have a string(char*), and i need to find its underlying datatype such as int, float, double, short, long, or just a character array containing alphabets with or with out digits(like varchar in SQL). For ex: char* str1 = "12312" char* str2 = "231.342" char* str3 = "234234243234" char* str4 = "4323434.2432342" char*...
The Wikipedia artcile on Effect system is currently just a short stub and I've been wondering for a while as to what is an effect system. Are there any languages that have an effect system in addition to a type system? What would a possible (hypothetical) notation in a mainstream language, that you're familiar, with look like with e...
This seems like a simple question, but I can't find it with the Stack Overflow search or Google. What does a type followed by a _t mean? Such as int_t anInt; I see it a lot in C code meant to deal closely with hardware—I can't help but think that they're related. ...
Hello everybody! How do I get the type of a generic typed class within the class? An example: I build a generic typed collection implementing ICollection< T>. Within I have methods like public void Add(T item){ ... } public void Add(IEnumerable<T> enumItems){ ... } How can I ask within the method f...
I know that it is possible (in theory) to create a new type at run-time, but is it possible to modify a method body of an existing type at run-time? My plan (if I can get this to work) is to tag up methods with a custom attribute, and then at run-time search for methods with the attribute, and insert some of my own code into the method b...
I want to create a base object that has only methods. The object would be QUEUABLE_OBJECT_TYPE and it will have an ENQUEUE method(s). The Payload of these messages (properties) would be added by subtyping this object. I get an error that makes it sound like you cannot. PLS-00589: no attributes found in object type "QUEUABLE_OBJECT_T...
Just out of curiosity: I know I can tell the compiler if I want a value to be interpreted as a certain numeric type, e.g. as Integer (32 bit signed) this way appending an "I" (type character) to the constant value: Private Function GetTheAnswerAsInteger() As Integer Return 42I End Function There's also "S" for Short or "D" for D...
I have a method with an out parameter that tries to do a type conversion. Basically: public void GetParameterValue(out object destination) { object paramVal = "I want to return this. could be any type, not just string."; destination = null; // default out param to null destination = Convert.ChangeType(pa...
Is there a native c++ variable type that's "bigger" than a double? float is 7 double is 15 (of course depending on the compiler) Is there anything bigger that's native, or even non-native? ...
