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.

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:
add
in interfaceAttributeSet
- Parameters:
attribute
- attribute value to be added to this attribute set- Returns:
true
if 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 theattribute
is not an instance of interfacePrintRequestAttribute
NullPointerException
- if theattribute
isnull
-
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:
addAll
in interfaceAttributeSet
- Parameters:
attributes
- whose elements are to be added to this attribute set- Returns:
true
if 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 interfacePrintRequestAttribute
NullPointerException
- if the specified set isnull
