All Superinterfaces:

AttributeSet

All Known Implementing Classes:

HashPrintRequestAttributeSet
```
public interface PrintRequestAttributeSet
extends AttributeSet
```
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 Summary

All Methods Instance Methods Abstract 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.

```
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:
    
    add in interface AttributeSet
    
    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 the add() operation
    
    ClassCastException - if the attribute is not an instance of interface PrintRequestAttribute
    
    NullPointerException - if the attribute is null
  - 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:
    
    addAll in interface AttributeSet
    
    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 the addAll() method
    
    ClassCastException - if some element in the specified set is not an instance of interface PrintRequestAttribute
    
    NullPointerException - if the specified set is null
