Class Media

java.lang.Object
  extended by javax.print.attribute.EnumSyntax
      extended by javax.print.attribute.standard.Media
All Implemented Interfaces:
Serializable, Cloneable, Attribute, DocAttribute, PrintJobAttribute, PrintRequestAttribute
Direct Known Subclasses:
MediaName, MediaSizeName, MediaTray

public abstract class Media
extends EnumSyntax
implements DocAttribute, PrintRequestAttribute, PrintJobAttribute

Class Media is a printing attribute class that specifies the medium on which to print.

Media may be specified in different ways.

Each of these corresponds to the IPP "media" attribute. The current API does not support describing media by characteristics (eg colour, opacity). This may be supported in a later revision of the specification.

A Media object is constructed with a value which represents one of the ways in which the Media attribute can be specified.

IPP Compatibility: The category name returned by getName() is the IPP attribute name. The enumeration's integer value is the IPP enum value. The toString() method returns the IPP string representation of the attribute value.

getCategory

public final Class<? extends Attribute> getCategory()
Get the printing attribute class which is to be used as the "category" for this printing attribute value.

For class Media and any vendor-defined subclasses, the category is class Media itself.

Specified by:
getCategory in interface Attribute
Returns:
Printing attribute class (category), an instance of class java.lang.Class.

getName

public final String getName()
