Inherited functions

From class AccessibilityDelegateCompat

`Boolean`	`dispatchPopulateAccessibilityEvent(host: View!, event: AccessibilityEvent!)` Dispatches an `AccessibilityEvent` to the host `View` first and then to its children for adding their text content to the event. The default implementation behaves as `View#dispatchPopulateAccessibilityEvent(AccessibilityEvent)` for the case of no accessibility delegate been set.
`AccessibilityNodeProviderCompat!`	`getAccessibilityNodeProvider(host: View!)` Gets the provider for managing a virtual view hierarchy rooted at this View and reported to `android.accessibilityservice.AccessibilityService`s that explore the window content. The default implementation behaves as `ViewCompat#getAccessibilityNodeProvider(View)` for the case of no accessibility delegate been set.
`Unit`	`onPopulateAccessibilityEvent(host: View!, event: AccessibilityEvent!)` Gives a chance to the host View to populate the accessibility event with its text content. The default implementation behaves as `ViewCompat#onPopulateAccessibilityEvent(AccessibilityEvent)` for the case of no accessibility delegate been set.
`Boolean`	`onRequestSendAccessibilityEvent(host: ViewGroup!, child: View!, event: AccessibilityEvent!)` Called when a child of the host View has requested sending an `AccessibilityEvent` and gives an opportunity to the parent (the host) to augment the event. The default implementation behaves as `ViewGroupCompat#onRequestSendAccessibilityEvent(ViewGroup, View, AccessibilityEvent)` for the case of no accessibility delegate been set.
`Unit`	`sendAccessibilityEvent(host: View!, eventType: Int)` Sends an accessibility event of the given type. If accessibility is not enabled this method has no effect. The default implementation behaves as `View#sendAccessibilityEvent(int)` for the case of no accessibility delegate been set.
`Unit`	`sendAccessibilityEventUnchecked(host: View!, event: AccessibilityEvent!)` Sends an accessibility event. This method behaves exactly as `sendAccessibilityEvent(View, int)` but takes as an argument an empty `AccessibilityEvent` and does not perform a check whether accessibility is enabled. The default implementation behaves as `View#sendAccessibilityEventUnchecked(AccessibilityEvent)` for the case of no accessibility delegate been set.
