Not called directly by applications.

  Not called directly by applications.
Implemented by a service provider, and called by the print lookup
service
Returns: the default PrintService for this lookup service. If there is no default, returns null.

  Not called directly by applications.

  Not called directly by applications.

Implemented by a service provider, used by the static methods of this class.

Locates MultiDoc print services which can be positively confirmed to support the combination of attributes and DocFlavors specified.

Returns: array of matching PrintServices. If no services match, the array is zero-length.
Parameters:
- flavors - of documents required. If null or empty it is ignored.
- attributes - required to be supported. If null this constraint is not used.

  Not called directly by applications.

  Not called directly by applications.
Implemented by a service provider, used by the static methods
of this class.
Returns: array of all PrintServices known to this lookup service class. If none are found, the array is zero-length.

  Locates services that can be positively confirmed to support the combination of attributes and DocFlavors specified.

  Locates services that can be positively confirmed to support the combination of attributes and DocFlavors specified. This method is not called directly by applications.

Implemented by a service provider, used by the static methods of this class.

The results should be the same as obtaining all the PrintServices and querying each one individually on its support for the specified attributes and flavors, but the process can be more efficient by taking advantage of the capabilities of lookup services for the print services.
Returns: array of matching PrintServices. If no services match, the array is zero-length.
Parameters:
- flavor - of document required. If null it is ignored.
- attributes - required to be supported. If null this constraint is not used.

  Locates the default print service for this environment.

  Locates the default print service for this environment. This may return null. If multiple lookup services each specify a default, the chosen service is not precisely defined, but a platform native service, rather than an installed service, is usually returned as the default. If there is no clearly identifiable platform native default print service, the default is the first to be located in an implementation-dependent manner.

This may include making use of any preferences API that is available as part of the Java or native platform. This algorithm may be overridden by a user setting the property javax.print.defaultPrinter. A service specified must be discovered to be valid and currently available to be returned as the default.
Returns: the default PrintService.

  Locates MultiDoc print Services capable of printing MultiDocs containing all the specified doc flavors.

  Locates MultiDoc print Services capable of printing MultiDocs containing all the specified doc flavors.

This method is useful to help locate a service that can print a MultiDoc in which the elements may be different flavors. An application could perform this itself by multiple lookups on each DocFlavor in turn and collating the results, but the lookup service may be able to do this more efficiently.
Returns: array of matching {@link MultiDocPrintService} objects. If no services match, the array is zero-length.
Parameters:
- flavors - the flavors to print. If null or empty this constraint is not used. Otherwise return only multidoc print services that can print all specified doc flavors.
- attributes - attributes that the print service must support. If null this constraint is not used.

  Locates print services capable of printing the specified DocFlavor.

  Locates print services capable of printing the specified
DocFlavor.
Returns: array of matching PrintService objects representing print services that support the specified flavor attributes. If no services match, the array is zero-length.
Parameters:
- flavor - the flavor to print. If null, this constraint is not used.
- attributes - attributes that the print service must support. If null this constraint is not used.

  Allows an application to directly register an instance of a class which implements a print service.

  Allows an application to directly register an instance of a
class which implements a print service.
The lookup operations for this service will be
performed by the PrintServiceLookup class using the attribute
values and classes reported by the service.
This may be less efficient than a lookup
service tuned for that service.
Therefore registering a PrintServiceLookup instance
instead is recommended.
The method returns true if this service is not previously
registered and is now successfully registered.
This method should not be called with StreamPrintService instances.
They will always fail to register and the method will return false.
Returns: true if the service is newly registered; false otherwise.
Parameters:
- service - an implementation of a print service.

  Allows an application to explicitly register a class that implements lookup services.

  Allows an application to explicitly register a class that implements lookup services. The registration will not persist across VM invocations. This is useful if an application needs to make a new service available that is not part of the installation. If the lookup service is already registered, or cannot be registered, the method returns false.

Returns: true if the new lookup service is newly registered; false otherwise.
Parameters:
- sp - an implementation of a lookup service.
