getAll method
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
- the IDBObjectStore.openCursor method with the same key. That method provides a cursor if the record exists, and no cursor if it does not.
- 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,
]);
