Is it possible to get the type name of a generic type?

Question

I have a method signature of execute<TResult>(): Observable<TResult>

How do I get the name of the TResult type?

Example:

execute<ViewModel> --> "ViewModel" is the result I need.

Answer 1

As far as I know it is not possible to get the name of TResult, but if you provide the accordingly constructor function you can get the name.

Declaration:

execute<TResult>(ctor: { new (): TResult }) : <TResult> {
  console.log(ctor.name) //Prints out SomeClass
  return <any>null;
}

Usage:

execute<SomeClass>(SomeClass);
