Map
MongooseMap.prototype.$isMongooseMap
MongooseMap.prototype.clear()
MongooseMap.prototype.delete()
MongooseMap.prototype.get()
MongooseMap.prototype.set()
MongooseMap.prototype.toBSON()
MongooseMap.prototype.toJSON()
MongooseMap.prototype.$isMongooseMap
Type:
- «property»
Set to true
for all Mongoose map instances
MongooseMap.prototype.clear()
Overwrites native Map's clear()
function to support change tracking.
MongooseMap.prototype.delete()
Overwrites native Map's delete()
function to support change tracking.
MongooseMap.prototype.get()
Overwrites native Map's get()
function to support Mongoose getters.
MongooseMap.prototype.set()
Overwrites native Map's set()
function to support setters, populate()
,
and change tracking. Note that Mongoose maps only support strings and
ObjectIds as keys.
Example:
doc.myMap.set('test', 42); // works
doc.myMap.set({ obj: 42 }, 42); // Throws "Mongoose maps only support string keys"
MongooseMap.prototype.toBSON()
Converts this map to a native JavaScript Map so the MongoDB driver can serialize it.
MongooseMap.prototype.toJSON()
Parameters:
[options]
«Object»[options.flattenMaps=false]
«Boolean» set totrue
to convert the map to a POJO rather than a native JavaScript map
Converts this map to a native JavaScript Map for JSON.stringify()
. Set
the flattenMaps
option to convert this map to a POJO instead.
Example:
doc.myMap.toJSON() instanceof Map; // true
doc.myMap.toJSON({ flattenMaps: true }) instanceof Map; // false
