javax.print.attribute
public interface: PrintServiceAttributeSet [javadoc | source]

All Implemented Interfaces:
AttributeSet

All Known Implementing Classes:
SynchronizedPrintServiceAttributeSet, HashPrintServiceAttributeSet, UnmodifiablePrintServiceAttributeSet

Interface PrintServiceAttributeSet specifies the interface for a set of print job attributes, i.e. printing attributes that implement interface 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.

Method from javax.print.attribute.PrintServiceAttributeSet Summary:
add, addAll

Method from javax.print.attribute.PrintServiceAttributeSet Detail:
public 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).
public boolean addAll(AttributeSet attributes) 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.

Method from javax.print.attribute.PrintServiceAttributeSet Detail:

 public 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).

 public boolean addAll(AttributeSet attributes)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.
