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.

`int`	`getValue()`	Returns this enumeration value's integer value.
`int`	`hashCode()`	Returns a hash code value for this enumeration value.
`protected Object`	`readResolve()`	During object input, convert this deserialized enumeration instance to the proper enumeration value defined in the enumeration attribute class.
`String`	`toString()`	Returns a string value corresponding to this enumeration value.

equals, finalize, getClass, notify, notifyAll, wait, wait, wait

Modifier and Type	Method	Description
`boolean`	`equals(Object obj)`	Indicates whether some other object is "equal to" this one.
`protected void`	`finalize()`	Deprecated, for removal: This API element is subject to removal in a future version. Finalization is deprecated and subject to removal in a future release.
`final Class<?>`	`getClass()`	Returns the runtime class of this `Object`.
`final void`	`notify()`	Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()`	Wakes up all threads that are waiting on this object's monitor.
`final void`	`wait()`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
`final void`	`wait(long timeoutMillis)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis, int nanos)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

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 name is "compression".

Specified by:: getName in interface Attribute
Returns:: attribute category name
