Method Detail

getService

public static Object getService(Class service_class,
                                String selector,
                                Object requestor)
                         throws wt.services.applicationcontext.UnableToCreateServiceException

Returns an implementation of a service object based upon the supplied arguments.

Supported API: true

Parameters:

service_class - Class of the service that is desired. This is required. In typical usage, this is a java Interface the service object returned must implement. The lookup for the particular service implementer is refined by indicating a selector and/or a target object (requestor) that is in need of the service.

selector - A selector further qualifies the request for the service. It may also be used instead of a requestor object to request the service. This latter technique is used when a simple string can indicate which variant of the service is needed, rather than supplying a java class.

requestor - An object that is the target of the request for service. The typical meaning is the the requestor object needs the service. Java inheritance using the class of the requestor to help determine which service implementation is returned. If the requestor is a Class object, inheritance based upon the class that the requestor represents is used in the determination.

Returns:

Object

Throws:

wt.services.applicationcontext.UnableToCreateServiceException
