Creates a new instance wrapping an AccessibilityNodeInfo.

Adds an action that can be performed on the node.

Note: Cannot be called from an AccessibilityService. This class is made immutable before being delivered to an AccessibilityService.

Adds a child.

Note: Cannot be called from an AccessibilityService. This class is made immutable before being delivered to an AccessibilityService.

Adds a virtual child which is a descendant of the given root. If virtualDescendantId is NO_ID the root is added as a child.

A virtual descendant is an imaginary View that is reported as a part of the view hierarchy for accessibility purposes. This enables custom views that draw complex content to report them selves as a tree of virtual views, thus conveying their logical structure.

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Finds AccessibilityNodeInfos by text. The match is case insensitive containment. The search is relative to this info i.e. this info is the root of the traversed tree.

Note: It is a client responsibility to recycle the received info by calling recycle() to avoid creating of multiple instances.

Find the view that has the specified focus type. The search starts from the view represented by this node info.

Searches for the nearest view in the specified direction that can take input focus.

Gets the actions that can be performed on the node.

Gets the node bounds in parent coordinates.

Gets the node bounds in screen coordinates.

Get the child at given index.

Note: It is a client responsibility to recycle the received info by calling recycle() to avoid creating of multiple instances.

Gets the number of children.

Gets the class this node comes from.

Gets the content description of this node.

Gets the node's live region mode.

A live region is a node that contains information that is important for the user and when it changes the user should be notified. For example, in a login screen with a TextView that displays an "incorrect password" notification, that view should be marked as a live region with mode ACCESSIBILITY_LIVE_REGION_POLITE.

It is the responsibility of the accessibility service to monitor TYPE_WINDOW_CONTENT_CHANGED events indicating changes to live region nodes and their children.

Gets the movement granularities for traversing the text of this node.

Gets the package this node comes from.

Gets the parent.

Note: It is a client responsibility to recycle the received info by calling recycle() to avoid creating of multiple instances.

Gets the text of this node.

Gets the fully qualified resource name of the source view's id.

Note: The primary usage of this API is for UI test automation and in order to report the source view id of an AccessibilityNodeInfoCompat the client has to set the FLAG_REPORT_VIEW_IDS flag when configuring his AccessibilityService.

Gets the id of the window from which the info comes from.

Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Sets the parent to be a virtual descendant of the given root. If virtualDescendantId equals to NO_ID the root is set as the parent.

A virtual descendant is an imaginary View that is reported as a part of the view hierarchy for accessibility purposes. This enables custom views that draw complex content to report them selves as a tree of virtual views, thus conveying their logical structure.

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

   getClass().getName() + '@' + Integer.toHexString(hashCode())
