ej.mwt.style.outline.border

Class RoundedBorder

java.lang.Object

ej.mwt.style.outline.border.RoundedBorder

All Implemented Interfaces:

Outline

public class RoundedBorder
extends Object
implements Outline

Draws a uniform border with round corners.

May be associated with RoundedBackground or used on its own.

The thickness and corner radius are stored as a char for heap optimization and therefore cannot exceed 65535.

Constructor Detail

RoundedBorder

public RoundedBorder(int color,
                     int cornerRadius,
                     int thickness)

Creates a rounded border specifying its attributes.

The given corner radius and thickness are clamped between 0 and Character.MAX_VALUE.

Parameters:

color - the color.

cornerRadius - the corner radius.

thickness - the border thickness.

Method Detail

getColor

public int getColor()

Gets the color.

Returns:

the color.

getThickness

public int getThickness()

Gets the thickness.

Returns:

the thickness.

getCornerRadius

public int getCornerRadius()

Gets the corner radius.

Returns:

the corner radius.

apply

public void apply(Outlineable outlineable)

Description copied from interface: Outline

Removes the thickness of this outline from the given object.

Specified by:

apply in interface Outline

Parameters:

outlineable - the object to unwrap.

apply

public void apply(ej.microui.display.GraphicsContext g,
                  Size size)

Description copied from interface: Outline

Applies the outline on a graphics context.

Specified by:

apply in interface Outline

Parameters:

g - the graphics context.

size - the size to apply on.

equals

public boolean equals(@Nullable
                      Object obj)

Description copied from class: Object

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.

Specified by:

equals in interface Outline

Overrides:

equals in class Object

Parameters:

obj - the reference object with which to compare.

Returns:

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

hashCode

public int hashCode()

Description copied from class: Object

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 Object.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^TM programming language.)

Specified by:

hashCode in interface Outline

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.
