AppActivationContext

class AppActivationContext

extends ManagedObject

Represents the application state using a single ‘target’ path in URL format. Used by AppActivity classes to implement routing behavior. This class is overridden by specialized implementations to work with platform features, e.g. DOM navigation in a Web browser.

Note: An instance of this object is provided by the Application object (e.g. BrowserApplication), and is also available on all activities and views as activationContext.

Constructor

(): AppActivationContext

.target

string

The current full target path, in URL format without leading or trailing slashes (e.g. foo/bar/123), defaults to the empty string. Changes to this property automatically result in a change event being emitted on the activation context instance itself.

.navigate()

(_path: string): void

Navigate to given (relative) path, in URL format or :back to go back in history; to be overridden, the base implementation does nothing.

.match()

(path: string, activity?: AppActivity): MatchedPath

path — The activity path to match, without leading slashes (e.g. foo/bar). Paths with a trailing slash (e.g. foo/bar/) match the exact path as well as sub paths. Paths may contain partial captures as either :foo or *foo, matching a single segment without slashes and the full remainder of the target path, respectively - but not an empty segment. The prefix ./ is replaced with the path (string) of the closest parent activity that has a AppActivity.path string property.

activity — The activity that is used to search for parent activities if necessary.

Check if given activity path matches the current target path.

Returns: An object with properties for all partial captures if given path matches the current target, or undefined otherwise.
