class LocalToNonLocalClass[G <: CallbackGlobal] extends AnyRef
A memoized lookup of an enclosing non local class.
Let's consider an example of an owner chain:
pkg1 <- pkg2 <- class A <- object B <- class C <- def foo <- class Foo <- class Bar
For an object, we work with its moduleClass
so we can refer to everything as classes.
Classes A, B, C are non local so they are mapped to themselves. Classes Foo and Bar are local because
they are defined within method foo
.
Let's define non local class more precisely. A non local class is a class that is owned by either a package or another non local class. This gives rise to a recursive definition of a non local class that is used in the implementation of the mapping.
Thanks to memoization, the amortized cost of a lookup is O(1). We amortize over lookups of all class symbols in the current compilation run.
Additionally, you can query whether a given class is local. Check isLocal
's documentation.

Queries the cached information whether a class is a local class.
Queries the cached information whether a class is a local class. If there's no cached information about the class None is returned.
This method doesn't mutate the cache.
