public interface PrintServiceAttributeSet extends AttributeSet
PrintServiceAttribute. In the Print Service API, the Print Service instance uses a PrintServiceAttributeSet to report the status of the print service.
A PrintServiceAttributeSet is just an

|Modifier and Type||Method and Description|
Adds the specified attribute value to this attribute set if it is not already present, first removing any existing value in the same attribute category as the specified attribute value (optional operation).
Adds all of the elements in the specified set to this attribute.
boolean add(Attribute attribute)
attribute- Attribute value to be added to this attribute set.
UnmodifiableSetException- (unchecked exception) Thrown if this attribute set does not support the
ClassCastException- (unchecked exception) Thrown if the
attributeis not an instance of interface
NullPointerException- (unchecked exception) Thrown if the
boolean addAll(AttributeSet attributes)
operation had been applied to this attribute set successively with each element from the specified set. If none of the categories in the specified set are the same as any categories in this attribute set, the addAll() operation effectively modifies this attribute set so that its value is the union of the two sets.
The behavior of the
addAll() operation is unspecified if
the specified set is modified while the operation is in progress.
addAll() operation throws an exception, the effect
on this attribute set's state is implementation dependent; elements
from the specified set before the point of the exception may or
may not have been added to this attribute set.
attributes- whose elements are to be added to this attribute set.
UnmodifiableSetException- (Unchecked exception) Thrown if this attribute set does not support the addAll() method.
ClassCastException- (Unchecked exception) Thrown if some element in the specified set is not an instance of interface
NullPointerException- (Unchecked exception) Thrown if the specified set is null.
