Interface PrintRequestAttributeSet specifies the interface for a set of print request attributes, i.e. printing attributes that implement interface PrintRequestAttribute. The client uses a PrintRequestAttributeSet to specify the settings to be applied to a whole print job and to all the docs in the print job. 
 PrintRequestAttributeSet is just an AttributeSet whose constructors and mutating operations guarantee an additional invariant, namely that all attribute values in the PrintRequestAttributeSet must be instances of interface PrintRequestAttribute. The add(Attribute), and addAll(AttributeSet) operations are respecified below to guarantee this additional invariant.

category as the specified attribute value (optional operation).

    public boolean add(Attribute attribute);

    
Adds all of the elements in the specified set to this attribute. The outcome is the same as if the 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.
