Methods

close() → void
Close the query and free resources.
count() → int
Returns the number of matching Objects.
describe() → String
For internal testing purposes.
describeParameters() → String
For internal testing purposes.
find() → List<T>
Finds Objects matching the query.
findAsync() → Future<List<T>>
Like find, but runs the query operation asynchronously in a worker isolate.
findFirst() → T?
Finds the first object matching the query. Returns null if there are no results. Note: offset and limit are respected, if set.
findFirstAsync() → Future<T?>
Like findFirst, but runs the query operation asynchronously in a worker isolate.
findIds() → List<int>
Finds Objects matching the query and returns their IDs.
findIdsAsync() → Future<List<int>>
Like findIds, but runs the query operation asynchronously in a worker isolate.
findUnique() → T?
Finds the only object matching the query. Returns null if there are no results or throws NonUniqueResultException if there are multiple objects matching.
findUniqueAsync() → Future<T?>
Like findUnique, but runs the query operation asynchronously in a worker isolate.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
property<DartType>(QueryProperty<T, DartType> prop) → PropertyQuery<DartType>
Use the same query conditions but only return a single property (field).
remove() → int
Removes all matching objects. Returns the number of removed objects.
removeAsync() → Future<int>
Like remove, but runs in a worker isolate.
stream() → Stream<T>
Finds Objects matching the query, streaming them while the query executes.
toString() → String
A string representation of this object.
