fully-satisfies?clj
(fully-satisfies? p v)Returns true if value v extends protocol p and implements every method in protocol p, otherwise false.
A value is considered to 'extend' protocol p either if:
- p implements the protocols interface, or
- p extends the protocol via clojure.core/extend, or
- p implements at least one method via metadata if supported by the protocol
Note that fully-satisfies? aims to be deterministic even in cases where protocol dispatch is non-deterministic, and so may be innaccurate in those cases.
In cases of multiple-inheritance of interfaces, fully-satisfies? will pick
an implementation by sorting the supers of the target object by name
and finding the first interface (from left to right) that implements
the protocol. Then, if it finds any more-specific interfaces (ie.,
sub-interfaces) of this interface in the target class hierarchy, it will pick
that interface's implementation (and apply this algorithm to a fixed point).
