Not setting this is kind of + silly, since that's the whole purpose of this lib, but it defaults + to `Infinity`. +* `maxAge` Maximum age in ms. Items are not pro-actively pruned out + as they age, but if you try to get an item that is too old, it'll + drop it and return undefined instead of giving it to you. +* `length` Function that is used to calculate the length of stored + items. If you're storing strings or buffers, then you probably want + to do something like `function(n, key){return n.length}`. The default is + `function(){return 1}`, which is fine if you want to store `max` + like-sized things. The item is passed as the first argument, and + the key is passed as the second argumnet. +* `dispose` Function that is called on items when they are dropped + from the cache. This can be handy if you want to close file + descriptors or do other cleanup tasks when items are no longer + accessible. Called with `key, value`. It's called *before* + actually removing the item from the internal cache, so if you want + to immediately put it back in, you'll have to do that in a + `nextTick` or `setTimeout` callback or it won't do anything. +* `stale` By default, if you set a `maxAge`, it'll only actually pull + stale items out of the cache when you `get(key)`. (That is, it's + not pre-emptively doing a `setTimeout` or anything.) If you set + `stale:true`, it'll return the stale value before deleting it. If + you don't set this, then it'll return `undefined` when you try to + get a stale entry, as if it had already been deleted. +* `noDisposeOnSet` By default, if you set a `dispose()` method, then + it'll be called whenever a `set()` operation overwrites an existing + key. If you set this option, `dispose()` will only be called when a + key falls out of the cache, not when it is overwritten. + +## API + +* `set(key, value, maxAge)` +* `get(key) => value` + + Both of these will update the "recently used"-ness of the key. + They do what you think. `maxAge` is optional and overrides the + cache `maxAge` option if provided. + + If the key is not found, `get()` will return `undefined`. + + The key and val can be any value. + +* `peek(key)` + + Returns the key value (or `undefined` if not found) without + updating the "recently used"-ness of the key. + + (If you find yourself using this a lot, you *might* be using the + wrong sort of data structure, but there are some use cases where + it's handy.) + +* `del(key)` + + Deletes a key out of the cache. + +* `reset()` + + Clear the cache entirely, throwing away all values. + +* `has(key)` + + Check if a key is in the cache, without updating the recent-ness + or deleting it for being stale. + +* `forEach(function(value,key,cache), [thisp])` + + Just like `Array.prototype.forEach`. Iterates over all the keys + in the cache, in order of recent-ness. (Ie, more recently used + items are iterated over first.) + +* `rforEach(function(value,key,cache), [thisp])` + + The same as `cache.forEach(...)` but items are iterated over in + reverse order. (ie, less recently used items are iterated over + first.) + +* `keys()` + + Return an array of the keys in the cache. + +* `values()` + + Return an array of the values in the cache. + +* `length` + + Return total length of objects in cache taking into account + `length` options function. + +* `itemCount` + + Return total quantity of objects currently in cache. Note, that + `stale` (see options) items are returned as part of this item + count. + +* `dump()` + + Return an array of the cache entries ready for serialization and usage + with 'destinationCache.load(arr)`. + +* `load(cacheEntriesArray)` + + Loads another cache entries array, obtained with `sourceCache.dump()`, + into the cache. The destination cache is reset before loading new entries + +* `prune()` + + Manually iterates over the entire cache proactively pruning old entries diff --git a/node_modules/named-placeholders/node_modules/lru-cache/index.js b/node_modules/named-placeholders/node_modules/lru-cache/index.js new file mode 100644 index 0000000..bd35b53 --- /dev/null +++ b/node_modules/named-placeholders/node_modules/lru-cache/index.js @@ -0,0 +1,468 @@ +'use strict' + +module.exports = LRUCache + +// This will be a proper iterable 'Map' in engines that support it, +// or a fakey-fake PseudoMap in older versions. +var Map = require('pseudomap') +var util = require('util') + +// A linked list to keep track of recently-used-ness +var Yallist = require('yallist') + +// use symbols if possible, otherwise just _props +var hasSymbol = typeof Symbol === 'function' && process.env._nodeLRUCacheForceNoSymbol !== '1' +var makeSymbol +if (hasSymbol) { + makeSymbol = function (key) { + return Symbol(key) + } +} else { + makeSymbol = function (key) { + return '_' + key + } +} + +var MAX = makeSymbol('max') +var LENGTH = makeSymbol('length') +var LENGTH_CALCULATOR = makeSymbol('lengthCalculator') +var ALLOW_STALE = makeSymbol('allowStale') +var MAX_AGE = makeSymbol('maxAge') +var DISPOSE = makeSymbol('dispose') +var NO_DISPOSE_ON_SET = makeSymbol('noDisposeOnSet') +var LRU_LIST = makeSymbol('lruList') +var CACHE = makeSymbol('cache') + +function naiveLength () { return 1 } + +// lruList is a yallist where the head is the youngest +// item, and the tail is the oldest. the list contains the Hit +// objects as the entries. +// Each Hit object has a reference to its Yallist.Node.
