Add multiple rules
Array of hints to add
The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.

Clear all hints
Callback method called with the resolved context instance or undefined.
Reference to the created Context Consumer Controller instance
Subscribe to a context. The callback fires when the context resolves, again if the context is replaced, and can also be invoked with undefined if the context is unprovided or the host disconnects. Use this whenever a controller or element needs the context at setup time — both for ongoing observation and for reading values immediately on resolve. This is the default choice; prefer it over getContext unless the context is only needed inside a later user action.
The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order.
Get all hints
Array of hints
Optionaloptions: UmbClassGetContextOptionsOptions for resolving the context once, including timeout-related behavior such as preventTimeout.
A Promise resolving to the Context API instance when available, or undefined when applicable.
Retrieve a context once as a Promise. Use this only when the context is first needed inside a user action or event handler that runs later (for example a button click, a property action, or an entity action execute()). For setup-time access — including a single immediate read — use consumeContext instead so the controller lifecycle handles resolution and cleanup. The returned Promise may reject if the context is not found before the default timeout; callers should handle rejection and/or pass preventTimeout in the options when waiting longer is expected.
Check if a hint exists
Unique value of the hint to check
True if the hint exists, false otherwise
An Observable to observe from.
Optionalcallback: ObserverCallback<SpecificT>Callback method called when data is changed.
OptionalcontrollerAlias: UmbControllerAlias | nullDefine an explicit controller alias. If not defined then one will be generated based on the callback function. If null is parsed no controller alias will be given.
Reference to the created Observer Controller instance.
Provide this validation context to a specific controller host. This can be used to Host a validation context in a Workspace, but provide it on a certain scope, like a specific Workspace View.
The controller host to provide this validation context to.
The API instance to be exposed.

Remove multiple hints
Array of unique values to remove
The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener() from the target.

This mixin enables a web-component to host controllers. This enables controllers to be added to the life cycle of this element.
