IDBCursor extension type

Note: Not to be confused with IDBCursorWithValue which is just an IDBCursor interface with an additional value property.

The IDBCursor interface of the IndexedDB API represents a cursor for traversing or iterating over multiple records in a database.

The cursor has a source that indicates which index or object store it is iterating over. It has a position within the range, and moves in a direction that is increasing or decreasing in the order of record keys. The cursor enables an application to asynchronously process all the records in the cursor's range.

You can have an unlimited number of cursors at the same time. You always get the same IDBCursor object representing a given cursor. Operations are performed on the underlying index or object store.

Methods

advance(int count) → void
The advance() method of the IDBCursor interface sets the number of times a cursor should move its position forward.
continue_([JSAny? key]) → void
The continue() method of the IDBCursor interface advances the cursor to the next position along its direction, to the item whose key matches the optional key parameter. If no key is specified, the cursor advances to the immediate next position, based on its direction.
continuePrimaryKey(JSAny? key, JSAny? primaryKey) → void
The continuePrimaryKey() method of the IDBCursor interface advances the cursor to the item whose key matches the key parameter as well as whose primary key matches the primary key parameter.
delete() → IDBRequest
The delete() method of the IDBCursor interface returns an IDBRequest object, and, in a separate thread, deletes the record at the cursor's position, without changing the cursor's position. Once the record is deleted, the cursor's value is set to null.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
inherited
update(JSAny? value) → IDBRequest
The update() method of the IDBCursor interface returns an IDBRequest object, and, in a separate thread, updates the value at the current position of the cursor in the object store. If the cursor points to a record that has just been deleted, a new record is created.

Operators

operator ==(Object other) → bool
The equality operator.
