PathInterpolatorCompat

public final class PathInterpolatorCompat
extends Object

java.lang.Object
↳	android.support.v4.view.animation.PathInterpolatorCompat

Helper for creating path-based Interpolator instances. On API 21 or newer, the platform implementation will be used and on older platforms a compatible alternative implementation will be used.

Summary

Public methods
`static Interpolator`	`create(Path path)` Create an `Interpolator` for an arbitrary `Path`.
`static Interpolator`	`create(float controlX1, float controlY1, float controlX2, float controlY2)` Create an `Interpolator` for a cubic Bezier curve.
`static Interpolator`	`create(float controlX, float controlY)` Create an `Interpolator` for a quadratic Bezier curve.

Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public methods

create

Interpolator create (Path path)

Create an Interpolator for an arbitrary Path. The Path must begin at (0, 0) and end at (1, 1). The x-coordinate along the Path is the input value and the output is the y coordinate of the line at that point. This means that the Path must conform to a function y = f(x).

The Path must not have gaps in the x direction and must not loop back on itself such that there can be two points sharing the same x coordinate.

Parameters
`path`	`Path`: the `Path` to use to make the line representing the `Interpolator`

Returns
`Interpolator`	the `Interpolator` representing the `Path`

create

Interpolator create (float controlX1, 
                float controlY1, 
                float controlX2, 
                float controlY2)

Create an Interpolator for a cubic Bezier curve. The end points (0, 0) and (1, 1) are assumed.

Parameters
`controlX1`	`float`: the x coordinate of the first control point of the cubic Bezier
`controlY1`	`float`: the y coordinate of the first control point of the cubic Bezier
`controlX2`	`float`: the x coordinate of the second control point of the cubic Bezier
`controlY2`	`float`: the y coordinate of the second control point of the cubic Bezier

Returns
`Interpolator`	the `Interpolator` representing the cubic Bezier curve

create

Interpolator create (float controlX, 
                float controlY)

Create an Interpolator for a quadratic Bezier curve. The end points (0, 0) and (1, 1) are assumed.

Parameters
`controlX`	`float`: the x coordinate of the quadratic Bezier control point
`controlY`	`float`: the y coordinate of the quadratic Bezier control point

Returns
`Interpolator`	the `Interpolator` representing the quadratic Bezier curve
