defmodule Explorer.Chain.MapCache do |
||||
@moduledoc """ |
||||
Behaviour for a map-like cache of elements. |
||||
|
||||
A macro based on `ConCache` is provided as well, at its minimum it can be used as; |
||||
``` |
||||
use Explorer.Chain.MapCache, |
||||
name: :name, |
||||
keys: [:fst, :snd] |
||||
``` |
||||
Note: `keys` can also be set singularly with the option `key`, e.g.: |
||||
``` |
||||
use Explorer.Chain.MapCache, |
||||
name: :cache, |
||||
key: :fst, |
||||
key: :snd |
||||
``` |
||||
Additionally all of the options accepted by `ConCache.start_link/1` can be |
||||
provided as well. By default only `ttl_check_interval:` is set (to `false`). |
||||
|
||||
## Named functions |
||||
Apart from the functions defined in the behaviour, the macro will also create |
||||
3 named function for each key, for instance for the key `:fst`: |
||||
- `get_fst` |
||||
- `set_fst` |
||||
- `update_fst` |
||||
These all work as their respective counterparts with the `t:key/0` parameter. |
||||
|
||||
## Callbacks |
||||
Apart from the `callback` that can be set as part of the `ConCache` options, |
||||
two callbacks esist and can be overridden: |
||||
|
||||
`c:handle_update/3` will be called whenever an update is issued. It will receive |
||||
the `t:key/0` that is going to be updated, the current `t:value/0` that is |
||||
stored for said key and the new `t:value/0` to evaluate. |
||||
This allows to select what value to keep and do additional processing. |
||||
By default this just stores the new `t:value/0`. |
||||
|
||||
`c:handle_fallback/1` will be called whenever a get is performed and there is no |
||||
stored value for the given `t:key/0` (or when the value is `nil`). |
||||
It can return 2 different tuples: |
||||
- `{:update, value}` that will cause the value to be returned and the `t:key/0` |
||||
to be `c:update/2`d |
||||
- `{:return, value}` that will cause the value to be returned but not stored |
||||
This allows to define of a default value or perform some actions. |
||||
By default it will simply `{:return, nil}` |
