Methods
[iterator]()
[iterator]():
IterableIterator<[string,YTNode[]]>
Defined in: node_modules/typescript/lib/lib.es2015.iterable.d.ts:119
Returns an iterable of entries in the map.
Returns
IterableIterator<[string, YTNode[]]>

delete()
delete(
key):boolean
Defined in: node_modules/typescript/lib/lib.es2015.collection.d.ts:24
Parameters
key

true if an element in the Map existed and has been removed, or false if the element does not exist.
Inherited from
Map.delete
entries()
entries():
IterableIterator<[string,YTNode[]]>
Defined in: node_modules/typescript/lib/lib.es2015.iterable.d.ts:124
Returns an iterable of key, value pairs for every entry in the map.

forEach()
forEach(
callbackfn,thisArg?):void
Defined in: node_modules/typescript/lib/lib.es2015.collection.d.ts:28
Executes a provided function once per each key/value pair in the Map, in insertion order.
Parameters
callbackfn
(value, key, map) => void
thisArg?
any
Returns
void
Inherited from
Map.forEach
get()
get(
key):YTNode[] |undefined
Defined in: node_modules/typescript/lib/lib.es2015.collection.d.ts:33
Returns a specified element from the Map object. If the value that is associated to the provided key is an object, then you will get a reference to that object and any change made to that object will effectively modify it inside the Map.
Parameters
key
string
Returns
YTNode[] | undefined
Returns the element associated with the specified key. If no element is associated with the specified key, undefined is returned.
