## Constructor Details

### HashPrintRequestAttributeSet

public HashPrintRequestAttributeSet()
Construct a new, empty print request attribute set.

### HashPrintRequestAttributeSet

public HashPrintRequestAttributeSet(PrintRequestAttribute attribute)
Construct a new print request attribute set, initially populated with the given value.

Parameters:
  `attribute` - attribute value to add to the set
Throws:
  `NullPointerException` - if `attribute` is `null`

### HashPrintRequestAttributeSet

public HashPrintRequestAttributeSet(PrintRequestAttribute[] attributes)
Construct a new print request attribute set, initially populated with the values from the given array. The new attribute set is populated by adding the elements of `attributes` array to the set in sequence, starting at index 0. Thus, later array elements may replace earlier array elements if the array contains duplicate attribute values or attribute categories.

Parameters:
  `attributes` - array of attribute values to add to the set. If `null`, an empty attribute set is constructed.
Throws:
  `NullPointerException` - if any element of `attributes` is `null`

### HashPrintRequestAttributeSet

public HashPrintRequestAttributeSet(PrintRequestAttributeSet attributes)
Construct a new attribute set, initially populated with the values from the given set where the members of the attribute set are restricted to the `(PrintRequestAttributeSe` interface.

Parameters:
  `attributes` - set of attribute values to initialise the set. If `null`, an empty attribute set is constructed.
Throws:
  `ClassCastException` - if any element of `attributes` is not an instance of `PrintRequestAttributeSe`
