Class PrintServiceLookup
PrintServiceLookup implementations provide a way to lookup
print services based on different constraints.
Implementations are located and loaded automatically through the SPI JAR
file specification. Therefore implementation classes must provide a default
constructor for instantiation. Furthermore, applications are able to
register further instances directly at runtime.
If an SecurityManager is installed implementors should call
checkPrintJobAccess() to disable access for untrusted code.
This check is to be made in every lookup service implementation for
flexibility. Print services registered by applications through
registerService(PrintService) are suppressed in the
lookup results if a security manager is installed and disallows access.

getDefaultPrintService
public abstract PrintService getDefaultPrintService()
Not to be called directly by applications.
- The default lookup service of the implementing lookup service or
null if there is no default one.
getMultiDocPrintServices
public abstract MultiDocPrintService[] getMultiDocPrintServices(DocFlavor[] flavors,
AttributeSet attributes) Not to be called directly by applications.
flavors - the document flavors which have to be supported.attributes - the attributes which have to be supported.
- The multidoc print services of the implementing lookup service
for the given parameters, or an array of length 0 if none is available.
getPrintServices
public abstract PrintService[] getPrintServices()
Not to be called directly by applications.
- All known print services of the implementing lookup service
regardless of supported features, or an array of length 0 if none is
available.
getPrintServices
public abstract PrintService[] getPrintServices(DocFlavor flavor,
AttributeSet attributes) Not to be called directly by applications.
flavor - the document flavor which has to be supported.attributes - the attributes which have to be supported.
- The print services of the implementing lookup service
for the given parameters, or an array of length 0 if none is available.
lookupDefaultPrintService
public static final PrintService lookupDefaultPrintService()
Searches the default print service in the current environment.
If multiple lookup services are registered and each has a default
print service the result is not specified. Usually the default
print service of the native platform lookup service is returned.
The GNU classpath implementation will return the CUPS default
printing service as the default print service, if available.
The default print service may be overriden by users through
the property
javax.print.defaultPrinter. A service
specified must be found to be returned as the default.
- The default print service, or
null if none found.
lookupMultiDocPrintServices
public static final MultiDocPrintService[] lookupMultiDocPrintServices(DocFlavor[] flavors,
AttributeSet attributes) Searches print services capable of multi document printing in all of the
given document flavors and supporting the specified printing attributes.
flavors - the document flavors to support. If null this
constraint is ignored during lookup.attributes - the printing attributes to support. If
null this constraint is ignored during lookup.
- The resulting available multi document print services, or an
array of length 0 if none is found.
lookupPrintServices
public static final PrintService[] lookupPrintServices(DocFlavor flavor,
AttributeSet attributes) Searches print services capable of printing in the given document flavor
which supports the specified printing attributes.
flavor - the document flavor to support. If null this
constraint is ignored during lookup.attributes - the printing attributes to support. If
null this constraint is ignored during lookup.
- The resulting available print services, or an array of length 0
if none is found.
registerService
public static boolean registerService(PrintService service)
Explicitly registers the provided print service instance.
The registration will silently fail (returning
false) if
the print service instance is already registered or the registration
somehow else fails.
service - the single print service to register.
true if registered, false otherwise.
registerServiceProvider
public static boolean registerServiceProvider(PrintServiceLookup sp)
Explicitly registers the provided print service lookup implementation.
The registration will silently fail (returning
false) if
the lookup service is already registered or the registration somehow
else fails.
sp - the print service lookup implementation to register.
true if registered, false otherwise.
