Jan 22, 2009 · Every type in C# directly or indirectly derives from the object class type, and object is the ultimate base class of all types. Values of reference types are treated as objects simply by viewing the values as type object.

The Java type system, as exposed by the reflection API, has two types: Class<T> class and Type interface, which the former implements. In this system, a class (an element that is described by an instance of Class<T> ) is any type created with the keyword class or interface , any primitive type, any array thereof, and void .

Sep 8, 2016 · In Java, you can give a class to a method as a parameter using the type "Class". I didn't find anything similar in the typescript docs - is it possible to hand a class to a method? And if so, does the type "any" include such class-types?

Mar 12, 2016 · The python hierarchy is Type (Metaclass) -> Class -> Instance. Think of the function type() as going one level up. If you use the function type() on an instance of an int (any integer) like so: type(123) you will receive the class of the instance which in this case is int.

Aug 4, 2016 · It would be weird that a Type would be anything else than a Class... Javadoc for Type says. All Known Implementing Classes: Class . So unless you have special libraries that use non Class Types, you can simply cast - but you must be ready for a possible ClassCastException. Beware: Java use undocumented Type implementation to represent generics ...

Feb 9, 2010 · Determine the type of an object with type >>> obj = object() >>> type(obj) <class 'object'> Although it works, avoid double underscore attributes like __class__ - they're not semantically public, and, while perhaps not in this case, the builtin functions usually have better behavior. >>> obj.__class__ # avoid this! <class 'object'> type checking

Nov 25, 2015 · The point of new-style classes was to unify class and type. Technically speaking, __class__ is the only solution that will work both for new and old-style class instances, but it will also throw an exception on old-style class objects themselves. You can call type() on any object, but not every object has __class__.

A Generic Class is a class which can work on any type of data type or in other words we can say it is data type independent. public class Shape<T> { // T stands for "Type" private T t; public void set(T t) { this.t = t; } public T get() { return t; } } Where T means type. Now when you create instance of this Shape class you will need to tell ...

Feb 26, 2012 · For the curious, to build a table of conversions of NumPy array scalars for your system:. for name in dir(np): obj = getattr(np, name) if hasattr(obj, 'dtype'): try ...

Jan 6, 2010 · That is a strange example. Since generics are not reified in runtime runtime casting bypasses the generic type system in many cases. Generics are mostly a compile time construct that allows you to further constrain a type from a class type.
