Interface 
PrintJobAttributeSet specifies the interface for a set of
 print job attributes, i.e. printing attributes that implement interface
 PrintJobAttribute. In the Print Service API, a
 service uses a PrintJobAttributeSet to report the status of a print
 job.
 
 A PrintJobAttributeSet is just an AttributeSet
 whose constructors and mutating operations guarantee an additional invariant,
 namely that all attribute values in the PrintJobAttributeSet must be
 instances of interface PrintJobAttribute. The
 add(Attribute), and
 addAll(AttributeSet) operations are respecified
 below to guarantee this additional invariant.

Method Details- 
addAdds 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).- Specified by:
- addin interface- AttributeSet
- Parameters:
- attribute- attribute value to be added to this attribute set
- Returns:
- trueif this attribute set changed as a result of the call, i.e., the given attribute value was not already a member of this attribute set
- Throws:
- UnmodifiableSetException- if this attribute set does not support the- add()operation
- ClassCastException- if the- attributeis not an instance of interface- PrintJobAttribute
- NullPointerException- if the- attributeis- null
 
- 
addAllAdds all of the elements in the specified set to this attribute. The outcome is the same as if theadd(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, theaddAll()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.- Specified by:
- addAllin interface- AttributeSet
- Parameters:
- attributes- whose elements are to be added to this attribute set
- Returns:
- trueif this attribute set changed as a result of the call
- Throws:
- UnmodifiableSetException- if this attribute set does not support the- addAll()method
- ClassCastException- if some element in the specified set is not an instance of interface- PrintJobAttribute
- NullPointerException- if the specified set is- null
