getDependencies method

  1. @protected
Object getDependencies (Element dependent)

Returns the dependencies value recorded for dependent with setDependencies.

Each dependent element is mapped to a single object value which represents how the element depends on this InheritedElement. This value is null by default and by default dependent elements are rebuilt unconditionally.

Subclasses can manage these values with updateDependencies so that they can selectively rebuild dependents in notifyDependents.

This method is typically only called in overrides of updateDependencies.
