public abstract class GestureBase<T extends GestureBase<T>> extends Object implements Gesture<T>
A base class for Gestures to extend to get some common functionality. updateState(GestureNode) is called when the the gesture is either PASSIVE or GREEDY and therefore primed to react to user interaction.

    Modifier and Type
    Method
    Description
    void
    cancel()
    Forcibly put this gesture into the UNQUALIFIED state, as a result of another gesture transitioning to GREEDY.
    react.SignalView<Boolean>
    completed()
    Dispatched when this gesture is completed.
    void
    evaluate(GestureNode node)
    Perform a potential state transition in this Gesture based on the most recent touch information.
    boolean
    greedy()
    Returns whether this gesture will be greedy.
    T
    greedy(boolean value)
    Greedy gestures will dispatch both a started() and completed() event, and are considered greedy because once their start conditions have been met, they will prevent other gestures from further consideration for dispatch.
    void
    start()
    Called at the start of a new user interaction, forcibly puts this gesture into the PASSIVE state.
    react.SignalView<Void>
    started()
    Dispatched if this gesture goes GREEDY.
    Gesture.State
    state()
    Return the current gesture state.
