PrintServiceAttributeSet (Java SE 15 & JDK 15) (original) (raw)
All Superinterfaces:
[AttributeSet](AttributeSet.html "interface in javax.print.attribute")
All Known Implementing Classes:
[HashPrintServiceAttributeSet](HashPrintServiceAttributeSet.html "class in javax.print.attribute")
public interface PrintServiceAttributeSet extends AttributeSet
Interface PrintServiceAttributeSet
specifies the interface for a set of print job attributes, i.e. printing attributes that implement interfacePrintServiceAttribute. In the Print Service API, the Print Service instance uses a PrintServiceAttributeSet
to report the status of the print service.
A PrintServiceAttributeSet
is just anAttributeSet whose constructors and mutating operations guarantee an additional invariant, namely that all attribute values in thePrintServiceAttributeSet
must be instances of interfacePrintServiceAttribute. Theadd(Attribute), andaddAll(AttributeSet) operations are respecified below to guarantee this additional invariant.
Method Summary
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. |

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](AttributeSet.html#add%28javax.print.attribute.Attribute%29)
in interface[AttributeSet](AttributeSet.html "interface in javax.print.attribute")
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](UnmodifiableSetException.html "class in javax.print.attribute")
- if this attribute set does not support theadd()
operation
[ClassCastException](../../../../java.base/java/lang/ClassCastException.html "class in java.lang")
- if theattribute
is not an instance of interface PrintServiceAttribute
[NullPointerException](../../../../java.base/java/lang/NullPointerException.html "class in java.lang")
- if theattribute
isnull
addAll
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 theaddAll()
operation is unspecified if the specified set is modified while the operation is in progress.
If theaddAll()
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](AttributeSet.html#addAll%28javax.print.attribute.AttributeSet%29)
in interface[AttributeSet](AttributeSet.html "interface in javax.print.attribute")
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](UnmodifiableSetException.html "class in javax.print.attribute")
- if this attribute set does not support theaddAll()
method
[ClassCastException](../../../../java.base/java/lang/ClassCastException.html "class in java.lang")
- if some element in the specified set is not an instance of interfacePrintServiceAttribute
[NullPointerException](../../../../java.base/java/lang/NullPointerException.html "class in java.lang")
- if the specified set isnull
