Description copied from interface: ObjectProvider
Provides an object based on an expression. The process of providing objects occurs within a particular context, which will typically be a service builder method, service contributor method, or service decorator method. The locator parameter provides access to the services visible to that context.

Specified by:
provide in interface ObjectProvider
objectType - the expected object type
annotationProvider - provides access to annotations (typically, the field or parameter to which an injection-related annotation is attached); annotations on the field or parameter may also be used when resolving the desired object
locator - locator for the context in which the provider is being used
the requested object, or null if this object provider can not supply an object
