Interface PrintServiceAttributeSet
- All Superinterfaces:
AttributeSet
- All Known Implementing Classes:
HashPrintServiceAttributeSet
public interface PrintServiceAttributeSet extends AttributeSet
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.
Methods
| Modifier and Type | Method | Description |
|---|---|---|
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). |
boolean | addAll(AttributeSet attributes) | Adds all of the elements in the specified set to this attribute. |

add
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).
- 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()operation -
ClassCastException- if theattributeis not an instance of interfacePrintServiceAttribute -
NullPointerException- if theattributeisnull
addAll
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.
- 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()method -
ClassCastException- if some element in the specified set is not an instance of interfacePrintServiceAttribute -
NullPointerException- if the specified set isnull - See Also:
