getAll method

IDBRequest getAll([
  1. JSAny? query,
  2. int count
])

The getAll() method of the IDBObjectStore interface returns an IDBRequest object containing all objects in the object store matching the specified parameter or all objects in the store if no parameters are given.

If a value is successfully found, then a structured clone of it is created and set as the result of the request object.

This method produces the same result for:

  • a record that doesn't exist in the database
  • a record that has an undefined value

To tell these situations apart, you either call

  1. the IDBObjectStore.openCursor method with the same key. That method provides a cursor if the record exists, and no cursor if it does not.
  2. the IDBObjectStore.count method with the same key, which will return 1 if the row exists and 0 if it doesn't.

Implementation

external IDBRequest getAll([
  JSAny? query,
  int count,
]);
