A JavaScript (JS) cache that can have multiple complex values as keys
npm install multi-key-cachejavascript
npm install multi-key-cache --save
`Use
Supports the following methods:Slim
set(keys, val) : Sets a value to a set of keys. Keys can be an array of values, an arguments structure, or any object with a length property and numerical property names.
get(keys) : Returns the value of a set of keys.
has(keys) : Returns true if the set of keys have a value, otherwise false.
delete(keys) : Deletes the value of a set of keys.values() : Returns array of all values.
keyNodes() : Returns array of all individual key nodes (not sets of keys).
`Examples:
javascript
var MultiKeyCache = require('multi-key-cache');
var multiKeyCache = new MultiKeyCache();multiKeyCache.set(['a', 'b', 'c'], 'my value'); // sets 'my value' to keys a b c
multiKeyCache.set(['a', 'b', 'd'], 'another value'); // sets 'another value' to keys a b d
multiKeyCache.get(['a', 'b', 'c']); // returns 'my value'
multiKeyCache.get(['a', 'b', 'd']); // returns 'another value'
multiKeyCache.get(['a', 'b', 'x']); // returns undefined
multiKeyCache.has(['a', 'b', 'c']); // returns true
multiKeyCache.delete(['a', 'b', 'c']); // deletes 'my value'
multiKeyCache.has(['a', 'b', 'c']); // returns false
multiKeyCache.get(['a', 'b', 'c']); // returns undefined
`Complex objects as keys:
javascript
var MultiKeyCache = require('multi-key-cache'),
multiKeyCache = new MultiKeyCache(),
arg1 = { a: 1 },
arg2 = [{ b: 2 }],
arg3 = { c: [{ d: 3 }] };
multiKeyCache.set([arg1, arg2, arg3], 'my value'); // sets 'my value' to complex keys
multiKeyCache.set([arg3, arg2, arg1], 'another value'); // sets 'another value' to completely unrelated set of complex keys
multiKeyCache.get([arg1, arg2, arg3]); // returns 'my value'
multiKeyCache.get({ 0: arg3, 1: arg2, 2: arg1, length: 3}); // returns 'another value', keys container doesn't have to be an array
multiKeyCache.delete({ 0: arg1, 1: arg2, 2: arg3, length: 3}); // deletes 'my value' and associated empty keys
multiKeyCache.has([arg1, arg2, arg3]); // returns false
multiKeyCache.get([arg1, arg2, arg3]); // returns undefined
