public final class Signature
Provides methods for encoding and decoding type and method signature strings.
This class provides static methods and constants only; it is not intended to be instantiated or subclassed by clients.
Provisional API: This class/interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is being made available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

For example:

Note: This method assumes that a type signature containing a '$'
is an inner type signature. While this is correct in most cases, someone could
define a non-inner type name containing a '$'
. Handling this
correctly in all cases would have required resolving the signature, which
generally not feasible.
