Variables

read onlykeyPath:Dynamic

The key path of this index. If null, this index is not auto-populated.

read onlymultiEntry:Bool

Affects how the index behaves when the result of evaluating the index's key path yields an array. If true, there is one record in the index for each item in an array of keys. If false, then there is one record for each key that is an array.

name:String

The name of this index.

read onlyobjectStore:ObjectStore

The name of the object store referenced by this index.

read onlyunique:Bool

If true, this index does not allow duplicate values for a key.

Methods

count(?key:Dynamic):Request

Returns an IDBRequest object, and in a separate thread, returns the number of records within a key range.

Throws:

null

DOMError

get(key:Dynamic):Request

Returns an IDBRequest object, and, in a separate thread, finds either the value in the referenced object store that corresponds to the given key or the first corresponding value, if key is an IDBKeyRange.

Throws:

null

DOMError

getAll(?key:Dynamic, ?limit:Int):Request

Returns an IDBRequest object, in a separate thread, finds all matching values in the referenced object store that correspond to the given key or are in range, if key is an IDBKeyRange.

Throws:

null

DOMError

getAllKeys(?key:Dynamic, ?limit:Int):Request

Returns an IDBRequest object, in a separate thread, finds all matching keys in the referenced object store that correspond to the given key or are in range, if key is an IDBKeyRange.

Throws:

null

DOMError

getKey(key:Dynamic):Request

Returns an IDBRequest object, and, in a separate thread, finds either the given key or the primary key, if key is an IDBKeyRange.

Throws:

null

DOMError

@:value({ direction : NEXT })openCursor(?range:Dynamic, direction:CursorDirection = NEXT):Request

Returns an IDBRequest object, and, in a separate thread, creates a cursor over the specified key range.

Throws:

null

DOMError

@:value({ direction : NEXT })openKeyCursor(?range:Dynamic, direction:CursorDirection = NEXT):Request

Returns an IDBRequest object, and, in a separate thread, creates a cursor over the specified key range, as arranged by this index.

Throws:

null

DOMError
