JIntent<T extends JState> class
abstract
Represents an action or event that can modify application state.
The JIntent class is an abstraction that encapsulates a specific
action or event that may result in a change to the application's state.
This concept helps to structure the application by clearly defining
the different actions and how they affect the state.
When implemented, an JIntent typically contains:
- A method to invoke the action (
run()). - Any parameters or dependencies required to perform the action.
Intents are used in conjunction with controllers to manage the logic and state changes within the application.

Properties
-
controller
→ JController<
T> -
The controller bound by the most recent invocation.
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- isCancelled → bool
-
Whether cancellation was requested for the current execution.
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- state → T
-
Provides easy access to the current state managed by the controller.

Methods
-
cancel(
) → void - Requests cooperative cancellation of the execution in progress.
-
invoke(
JController< T> controller) → Future<void> - Wires the controller before executing the logic. Not overridable; override onInvoke instead. An instance can be reused after completion, but overlapping invocations fail with StateError before rebinding it. Invoking against a disposed controller also fails with StateError.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onInvoke(
) → Future< void> - Contains the core logic of the intent.
-
run(
JController< T> controller) → Future<void> - Executes the intent. Not overridable; override onInvoke instead.
-
toString(
) → String -
A string representation of this object.

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