alter-caches-mapping clj

(alter-caches-mapping tag update-fn & update-fn-args)

Internal function. Modifies entire tagged cache map with the provided function. Applies the function as (fn [caches refs & other-update-fn-args])

assoc-cache-tags clj

(assoc-cache-tags index cache-tags ref)

Add Mount Point ref to tag index

bind clj

(bind fn-or-var mount-conf cache)

Bind a cache to a fn or var. Internal function.

configuration-props clj

create-mount clj

(create-mount f cache mount-conf)

mount-point clj

(mount-point obj)

Return active mount point from the object's meta.

MountPoint clj protocol

Protocol for cache mount

cached clj

(cached this args)

Return cached value, possibly invoking the function with the args to obtain the value. This should be a thread-safe atomic operation.

handle-event clj

(handle-event this evt)

Handles event using internal event handling mechanism, usually a function

invalidate-all clj

(invalidate-all this)

Invalidate all entries, returns Cache

put-all clj

(put-all this args-to-vals)

Add entries to cache, returns Cache

mounted-cache clj

(mounted-cache this)

get-tags clj

(get-tags this)

Coll of tags for this mount point

invalidate clj

Invalidate entry for args, returns Cache

if-cached clj

(if-cached this args)

Return cached value if present in cache or memento.base/absent otherwise.

as-map clj

(as-map this)

Returns the cache as a map. This does not imply a snapshot, as implementation might provide a weakly consistent view of the cache.

original-function clj

(original-function this)

Returns the original function

reify-mount-conf clj

(reify-mount-conf mount-conf)

Transform user given mount-conf to a canonical form of a map.

TaggedMountPoint clj

tags clj

Map tag to mount-point

UntaggedMountPoint clj

update-existing clj

(update-existing m ks update-fn)

Convenience function. Updates ks's that are present with the provided update fn.
