| javax.print.attribute.PrintRequestAttributeSet
All known Subclasses: javax.print.attribute.HashPrintRequestAttributeSet,
| PrintRequestAttributeSet | | public interface PrintRequestAttributeSet extends AttributeSet(Code) | | Interface PrintRequestAttributeSet specifies the interface for a set of
print request attributes, i.e. printing attributes that implement interface
PrintRequestAttribute 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 AttributeSet whose
constructors and mutating operations guarantee an additional invariant,
namely that all attribute values in the PrintRequestAttributeSet must be
instances of interface
PrintRequestAttribute PrintRequestAttribute .
The
PrintRequestAttributeSet.add(Attribute) add(Attribute) , and
PrintRequestAttributeSet.addAll(AttributeSet) addAll(AttributeSet) operations
are respecified below to guarantee this additional invariant.

| Method Summary | |
| 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).
Parameters:
attribute - Attribute value to be added to this attribute set. | | 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
PrintRequestAttributeSet.add(Attribute) add(Attribute)
operation had been applied to this attribute set successively with
each element from the specified set. |
| add | | public boolean add(Attribute attribute)(Code) | | 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).
Parameters:
attribute - Attribute value to be added to this attribute set. true if this attribute set changed as a result ofthe call, i.e., the given attribute value was not already a member of this attribute set.
throws:
UnmodifiableSetException - (unchecked exception) Thrown if this attribute set does not support the add() operation.
throws:
ClassCastException - (unchecked exception) Thrown if the attribute is not an instance of interfacePrintRequestAttribute PrintRequestAttribute.
throws:
NullPointerException - (unchecked exception) Thrown if the attribute is null. |
| addAll | | public boolean addAll(AttributeSet attributes)(Code) | | Adds all of the elements in the specified set to this attribute.
The outcome is the same as if the
PrintRequestAttributeSet.add(Attribute) 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.
Parameters:
attributes - whose elements are to be added to this attribute set. true if this attribute set changed as a result ofthe call.
throws:
UnmodifiableSetException - (Unchecked exception) Thrown if this attribute set does notsupport the addAll() method.
throws:
ClassCastException - (Unchecked exception) Thrown if some element in the specified set is not an instance of interface PrintRequestAttribute PrintRequestAttribute.
throws:
NullPointerException - (Unchecked exception) Thrown if the specified set is null.
