seconddispatch

sunpy.util.functools.seconddispatch(func)[source]

A variant of functools.singledispatch which dispatches on type of the second argument. Single-dispatch generic function decorator.

Transforms a function into a generic function, which can have different behaviours depending upon the type of its first argument. The decorated function acts as the default implementation, and additional implementations can be registered using the register() attribute of the generic function.
