java.lang.CloneNotSupportedException if the object's class does not support the Cloneable interface. Subclasses that override the clone method can also throw this exception to indicate that an instance cannot be cloned.

describeContents

Added in API level 4
open fun describeContents(): Int
Return
Int a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR

getBoundingBox

Added in API level 4
open fun getBoundingBox(): RectF!
Return
RectF! the bounding box of the gesture

getID

Added in API level 4
open fun getID(): Long
Return
Long the id of the gesture

getLength

Added in API level 4
open fun getLength(): Float

Calculates the total length of the gesture. When there are multiple strokes in the gesture, this returns the sum of the lengths of all the strokes.

Return
Float the length of the gesture
