public final class PrinterStateReasons extends HashMap<PrinterStateReason,Severity> implements PrintServiceAttribute
Class PrinterStateReasons is a printing attribute class, a set of enumeration values, that provides additional information about the printer's current state, i.e., information that augments the value of the printer's PrinterState
attribute.
Instances of PrinterStateReason
do not appear in a Print Service's attribute set directly. Rather, a PrinterStateReasons attribute appears in the Print Service's attribute set. The PrinterStateReasons attribute contains zero, one, or more than one PrinterStateReason
objects which pertain to the Print Service's status, and each PrinterStateReason
object is associated with a Severity
level of REPORT (least severe), WARNING, or ERROR (most severe). The printer adds a PrinterStateReason
object to the Print Service's PrinterStateReasons attribute when the corresponding condition becomes true of the printer, and the printer removes the PrinterStateReason
object again when the corresponding condition becomes false, regardless of whether the Print Service's overall PrinterState
also changed.
Class PrinterStateReasons inherits its implementation from class java.util.HashMap
. Each entry in the map consists of a PrinterStateReason
object (key) mapping to a Severity
object (value):
Unlike most printing attributes which are immutable once constructed, class PrinterStateReasons is designed to be mutable; you can add PrinterStateReason
objects to an existing PrinterStateReasons object and remove them again. However, like class java.util.HashMap
, class PrinterStateReasons is not multiple thread safe. If a PrinterStateReasons object will be used by multiple threads, be sure to synchronize its operations (e.g., using a synchronized map view obtained from class java.util.Collections
).
IPP Compatibility: The string values returned by each individual PrinterStateReason
object's and the associated Severity
object's toString()
methods, concatenated together with a hyphen ("-"
) in between, gives the IPP keyword value. The category name returned by getName()
gives the IPP attribute name.

public PrinterStateReasons()
Construct a new, empty printer state reasons attribute; the underlying hash map has the default initial capacity and load factor.
public PrinterStateReasons(int initialCapacity)
super a new, empty printer state reasons attribute; the underlying hash map has the given initial capacity and the default load factor.
initialCapacity
- Initial capacity.IllegalArgumentException
- if the initial capacity is less than zero.public PrinterStateReasons(int initialCapacity, float loadFactor)
Construct a new, empty printer state reasons attribute; the underlying hash map has the given initial capacity and load factor.
initialCapacity
- Initial capacity.loadFactor
- Load factor.IllegalArgumentException
- if the initial capacity is less than zero.public PrinterStateReasons(Map<PrinterStateReason,Severity> map)
Construct a new printer state reasons attribute that contains the same PrinterStateReason
-to-Severity
mappings as the given map. The underlying hash map's initial capacity and load factor are as specified in the superclass constructor HashMap(Map)
.
map
- Map to copy.NullPointerException
- (unchecked exception) Thrown if map
is null or if any key or value in map
is null.ClassCastException
- (unchecked exception) Thrown if any key in map
is not an instance of class PrinterStateReason
or if any value in map
is not an instance of class Severity
.public Severity put(PrinterStateReason reason, Severity severity)
Adds the given printer state reason to this printer state reasons attribute, associating it with the given severity level. If this printer state reasons attribute previously contained a mapping for the given printer state reason, the old value is replaced.

- Printer state reason. This must be an instance of class PrinterStateReason
.severity
- Severity of the printer state reason. This must be an instance of class Severity
.null

.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 PrinterStateReasons, the category is class PrinterStateReasons itself.
getCategory
in interface Attribute
java.lang.Class
.public final String getName()
Get the name of the category of which this attribute value is an instance.
For class PrinterStateReasons, the category name is "printer-state-reasons"
.
public Set<PrinterStateReason> printerStateReasonSet(Severity severity)
Obtain an unmodifiable set view of the individual printer state reason attributes at the given severity level in this PrinterStateReasons attribute. Each element in the set view is a PrinterStateReason
object. The only elements in the set view are the PrinterStateReason
objects that map to the given severity value. The set view is backed by this PrinterStateReasons attribute, so changes to this PrinterStateReasons attribute are reflected in the set view. The set view does not support element insertion or removal. The set view's iterator does not support element removal.
severity
- Severity level.PrinterStateReason
attributes at the given Severity
level.NullPointerException
- (unchecked exception) Thrown if severity
is null.
