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 Details
-
add
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).- Specified by:
addin interfaceAttributeSet- 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 theadd()operationClassCastException- if theattributeis not an instance of interfacePrintServiceAttributeNullPointerException- if theattributeisnull
-
addAll
Adds 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 interfaceAttributeSet- 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 theaddAll()methodClassCastException- if some element in the specified set is not an instance of interfacePrintServiceAttributeNullPointerException- if the specified set isnull- See Also:
