ArcShape

public class ArcShape
extends RectShape

java.lang.Object
↳	android.graphics.drawable.shapes.Shape
	↳	android.graphics.drawable.shapes.RectShape
		↳	android.graphics.drawable.shapes.ArcShape

Creates an arc shape. The arc shape starts at a specified angle and sweeps clockwise, drawing slices of pie.

The arc can be drawn to a Canvas with its own draw(android.graphics.Canvas, android.graphics.Paint) method, but more graphical control is available if you instead pass the ArcShape to a ShapeDrawable.

Public constructors

ArcShape

public ArcShape (float startAngle, 
                float sweepAngle)

ArcShape constructor.

Parameters
`startAngle`	`float`: the angle (in degrees) where the arc begins
`sweepAngle`	`float`: the sweep angle (in degrees). Anything equal to or greater than 360 results in a complete circle/oval.

Public methods

clone

public ArcShape clone ()

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

will be true, and that the expression:

 x.clone().getClass() == x.getClass()

will be true, but these are not absolute requirements. While it is typically the case that:

 x.clone().equals(x)

will be 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.

The method clone for class Object performs a specific cloning operation. First, if the class of this object does not implement the interface Cloneable, then a CloneNotSupportedException is thrown. Note that all arrays are considered to implement the interface Cloneable and that the return type of the clone method of an array type T[] is T[] where T is any reference or primitive type. Otherwise, this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment; the contents of the fields are not themselves cloned. Thus, this method performs a "shallow copy" of this object, not a "deep copy" operation.

The class Object does not itself implement the interface Cloneable, so calling the clone method on an object whose class is Object will result in throwing an exception at run time.

Returns
`ArcShape`	a clone of this instance.

Throws
`CloneNotSupportedException`

draw

public void draw (Canvas canvas, 
                Paint paint)

Draws this shape into the provided Canvas, with the provided Paint.

Before calling this, you must call resize(float, float).

Parameters
`canvas`	`Canvas`: the Canvas within which this shape should be drawn
`paint`	`Paint`: the Paint object that defines this shape's characteristics

equals

public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

It is reflexive: for any non-null reference value x, x.equals(x) should return true.
It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
`o`	`Object`: the reference object with which to compare.

Returns
`boolean`	`true` if this object is the same as the obj argument; `false` otherwise.

getOutline

public void getOutline (Outline outline)

Computes the Outline of the shape and return it in the supplied Outline parameter. The default implementation does nothing and outline is not changed.

Parameters
`outline`	`Outline`: the Outline to be populated with the result. Must be non-`null`. This value cannot be `null`.

getStartAngle

public final float getStartAngle ()

Returns
`float`	the angle (in degrees) where the arc begins

getSweepAngle

public final float getSweepAngle ()

Returns
`float`	the sweep angle (in degrees)

hashCode

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int`	a hash code value for this object.
