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 AttributeSet
whose constructors and mutating operations guarantee an additional
invariant,
namely that all attribute values in the PrintServiceAttributeSet must be
instances of interface PrintServiceAttribute
.
The add(Attribute)
, and
addAll(AttributeSet)
operations
are respecified below to guarantee this additional invariant.
Modifier and Type | Method and Description |
---|---|
boolean |
add(Attribute attribute)
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).
|
boolean |
addAll(AttributeSet attributes)
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 add()
operation.ClassCastException
- (unchecked exception) Thrown if the attribute
is
not an instance of interface
PrintServiceAttribute
.NullPointerException
- (unchecked exception) Thrown if the attribute
is null.boolean addAll(AttributeSet attributes)
add(Attribute)
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.
If the 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.
