| Class ReferenceUriSchemesSupported is a printing attribute class
an enumeration, that indicates a "URI scheme," such as "http:" or "ftp:",
that a printer can use to retrieve print data stored at a URI location.
If a printer supports doc flavors with a print data representation class of
"java.net.URL", the printer uses instances of class
ReferenceUriSchemesSupported to advertise the URI schemes it can accept.
The acceptable URI schemes are included as service attributes in the
lookup service; this lets clients search the
for printers that can get print data using a certain URI scheme. The
acceptable URI schemes can also be queried using the capability methods in
interface PrintService. However,
ReferenceUriSchemesSupported attributes are used solely for determining
acceptable URI schemes, they are never included in a doc's,
print request's, print job's, or print service's attribute set.
The Internet Assigned Numbers Authority maintains the
official
list of URI schemes.
Class ReferenceUriSchemesSupported defines enumeration values for widely
used URI schemes. A printer that supports additional URI schemes
can define them in a subclass of class ReferenceUriSchemesSupported.
IPP Compatibility: The category name returned by
getName() is the IPP attribute name. The enumeration's
integer value is the IPP enum value. The toString() method
returns the IPP string representation of the attribute value.
