GestureStroke
open class GestureStroke
| kotlin.Any | |
| ↳ | android.gesture.GestureStroke |
A gesture stroke started on a touch down and ended on a touch up. A stroke consists of a sequence of timed points. One or multiple strokes form a gesture.

Public methods
clearPath
open fun clearPath(): Unit
Invalidates the cached path that is used to render the stroke.
clone
open fun clone(): Any!
Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression:
x.clone() != x
x.clone().getClass() == x.getClass()
true, but these are not absolute requirements. While it is typically the case that:
x.clone().equals(x)
true, this is not an absolute requirement.
By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().
By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.
| Return | |
|---|---|
Any! |
a clone of this instance. |
| Exceptions | |
|---|---|
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. |
computeOrientedBoundingBox
open fun computeOrientedBoundingBox(): OrientedBoundingBox!
Computes an oriented bounding box of the stroke.
| Return | |
|---|---|
OrientedBoundingBox! |
OrientedBoundingBox |
toPath
open fun toPath(
width: Float,
height: Float,
numSample: Int
): Path!
Converts the stroke to a Path of a given number of points.
| Parameters | |
|---|---|
width |
Float: the width of the bounding box of the target path |
height |
Float: the height of the bounding box of the target path |
numSample |
Int: the number of points needed |
| Return | |
|---|---|
Path! |
the path |
