composite-effective-dispatch-valueclj
(composite-effective-dispatch-value dispatcher
actual-dispatch-value
method-dispatch-values)Combine multiple composite dispatch values into a single composite dispatch value that has the overall most-specific arg for each position, e.g.
;; String is more specific than Object; ::parrot is more specific than ::bird
(composite-effective-dispatch-value [[Object ::parrot] [String ::bird]]) ; -> [String ::parrot]
If the most-specific dispatch value is not composite, it returns it directly.
Combine multiple composite dispatch values into a single composite dispatch value that has the overall most-specific arg for each position, e.g. ```clj ;; String is more specific than Object; ::parrot is more specific than ::bird (composite-effective-dispatch-value [[Object ::parrot] [String ::bird]]) ; -> [String ::parrot] ``` If the most-specific dispatch value is not composite, it returns it directly.
effective-dispatch-valueclj
(effective-dispatch-value dispatcher
actual-dispatch-value
primary-methods
aux-methods)Given matching primary-methods and aux-methods for the actual-dispatch-value, determine the effective dispatch
value.
Given matching `primary-methods` and `aux-methods` for the `actual-dispatch-value`, determine the effective dispatch value.
non-composite-effective-dispatch-valueclj
(non-composite-effective-dispatch-value dispatcher
actual-dispatch-value
method-dispatch-values)Operates only on non-composite dispatch values. Determine the effective (most-specific) dispatch value that will be
used when dispatching on actual-dispatch-value. If there is a dispatch value in method-dispatch-values that
dominates all other method dispatch values, that is the effective dispatch value. Otherwise the actual dispatch
value will be used.
Example. Suppose a ::toucan is a ::can, and a ::toucan is a ::bird. If we dispatch off of ::toucan and
only have a method for ::bird, then ::bird is the effective dispatch value, because there are no other dispatch
values that are more specific that would cause other methods to be used; the result is the same as if we had
dispatched off of ::bird in the first place. However, if we add a ::can method, the effective dispatch value for
::toucan can no longer be ::bird, because a ::bird is not necessarily a ::can. Thus our effective dispatch
value would become ::toucan, since out of the three possibilities only a ::toucan is both a ::bird and a
::can.
Operates only on non-composite dispatch values. Determine the effective (most-specific) dispatch value that will be used when dispatching on `actual-dispatch-value`. If there is a dispatch value in `method-dispatch-values` that dominates all other method dispatch values, that is the effective dispatch value. Otherwise the actual dispatch value will be used. Example. Suppose a `::toucan` is a `::can`, and a `::toucan` is a `::bird`. If we dispatch off of `::toucan` and only have a method for `::bird`, then `::bird` is the effective dispatch value, because there are no other dispatch values that are more specific that would cause other methods to be used; the result is the same as if we had dispatched off of `::bird` in the first place. However, if we add a `::can` method, the effective dispatch value for `::toucan` can no longer be `::bird`, because a `::bird` is not necessarily a `::can`. Thus our effective dispatch value would become `::toucan`, since out of the three possibilities only a `::toucan` is both a `::bird` and a `::can`.
sort-dispatch-valuesclj
(sort-dispatch-values dispatcher dispatch-values)Sort dispatch values in order from most-specific-overall to least-specific-overall.

standard-effective-methodclj
(standard-effective-method method-combination
dispatcher
method-table
dispatch-value)Build an effective method using the 'standard' technique, taking the dispatch-value-method pairs in the
method-table, finiding applicable ones using dispatcher, and combining them using method-combination.
