Class Compression

java.lang.Object

javax.print.attribute.EnumSyntax

javax.print.attribute.standard.Compression

All Implemented Interfaces:

Serializable, Cloneable, Attribute, DocAttribute

public class Compression
extends EnumSyntax
implements DocAttribute

Class Compression is a printing attribute class, an enumeration, that specifies how print data is compressed. Compression is an attribute of the print data (the doc), not of the Print Job. If a Compression attribute is not specified for a doc, the printer assumes the doc's print data is uncompressed (i.e., the default Compression value is always NONE).

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.

UNIX compression technology.

Constructor Details

Compression

protected Compression(int value)

Construct a new compression enumeration value with the given integer value.

Parameters:

value - Integer value

Method Details

getStringTable

protected String[] getStringTable()

Returns the string table for class Compression.

Overrides:

getStringTable in class EnumSyntax

Returns:

the string table

getEnumValueTable

protected EnumSyntax[] getEnumValueTable()

Returns the enumeration value table for class Compression.

Overrides:

getEnumValueTable in class EnumSyntax

Returns:

the value table

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

Specified by:

getCategory in interface Attribute

Returns:

printing attribute class (category), an instance of class java.lang.Class

getName

public final String getName()

Get the name of the category of which this attribute value is an instance.

For class Compression and any vendor-defined subclasses, the category name is "compression".

Specified by:

getName in interface Attribute

Returns:

attribute category name
