Examples of javax.print.attribute.PrintServiceAttributeSet

javax.print.attribute.PrintServiceAttributeSet
Interface PrintServiceAttributeSet specifies the interface for a set of print job attributes, i.e. printing attributes that implement interface {@link PrintServiceAttribute 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 {@link AttributeSet AttributeSet}whose constructors and mutating operations guarantee an additional invariant, namely that all attribute values in the PrintServiceAttributeSet must be instances of interface {@link PrintServiceAttribute PrintServiceAttribute}. The {@link #add(Attribute) add(Attribute)}, and {@link #addAll(AttributeSet) addAll(AttributeSet)} operationsare respecified below to guarantee this additional invariant.
