Class PageAttributes
- java.lang.Object
-
- java.awt.PageAttributes
- All Implemented Interfaces:
Cloneable
public final class PageAttributes extends Object implements Cloneable
A set of attributes which control the output of a printed page.
Instances of this class control the color state, paper size (media type), orientation, logical origin, print quality, and resolution of every page which uses the instance. Attribute names are compliant with the Internet Printing Protocol (IPP) 1.1 where possible. Attribute values are partially compliant where possible.
To use a method which takes an inner class type, pass a reference to one of the constant fields of the inner class. Client code cannot create new instances of the inner class types because none of those classes has a public constructor. For example, to set the color state to monochrome, use the following code:
import java.awt.PageAttributes; public class MonochromeExample { public void setMonochrome(PageAttributes pageAttributes) { pageAttributes.setColor(PageAttributes.ColorType.MONOCHROME); } }
Every IPP attribute which supports an attributeName-default value has a corresponding setattributeNameToDefault
method. Default value fields are not provided.

equals
public boolean equals(Object obj)
Determines whether two PageAttributes are equal to each other.
Two PageAttributes are equal if and only if each of their attributes are equal. Attributes of enumeration type are equal if and only if the fields refer to the same unique enumeration object. This means that an aliased media is equal to its underlying unique media. Printer resolutions are equal if and only if the feed resolution, cross feed resolution, and units are equal.
- Overrides:
-
equals
in classObject
- Parameters:
-
obj
- the object whose equality will be checked. - Returns:
- whether obj is equal to this PageAttribute according to the above criteria.

Returns a hash code value for this PageAttributes.
- Overrides:
-
hashCode
in classObject
- Returns:
- the hash code.
