A function to turn on tracing for all methods of a S4 generic function.R. Gentleman
A generic function may have anidentifieras its name, or it may be anoperatorfunction. Remarks Generic functions are functions declared with one or more generic type parameters. They may be methods in aclassorstruct, or standalone functions. A single generic declaration implicitly declares a family...
Generic classes and methods combine reusability, type safety, and efficiency in a way that their nongeneric counterparts can't. Generic type parameters are replaced with the type arguments during compilation. In the preceding example, the compiler replaces T with int. Generics are most frequently ...
First, declare the generic function withinlined-generic-functionmetaclass. This metaclass is a subclass ofstandard-generic-function. Therefore, unless you use its special feature, it acts exactly the same as the normal generic functions. (defgenericplus(a b) (:generic-function-classinlined-generic...

In the next snippet, we define a fast generic functionop. (defgenericop(foo) (:generic-function-classfast-generic-functions:fast-generic-function)) Once we have loaded the definition ofop, we can add individual methods and seal some of them. In particular, we can add a method that special...
It won’t compile because we can’t return a type from a function. For instance, we can’t write this:return int;Code like that doesn’t compile, nor does it make any sense. We don’t, under most circumstance, want to return a type. Given the reflection tools built into the C# ...
As it can't know the concrete type of its parameter, there's no way for a function like the former to for example return a value of the same type as the parameter. The latter can of course use its type parameter T for that. Also, the former can't be used if SomeProtocol has Sel...
