Filter getLookupFilter()
ServiceLocator
API or due to
an @Inject resolution. The decision made by this filter will be cached and
used every time that Descriptor is subsequently looked up. No validation checks
should be done in the returned filter, it is purely meant to limit the
Descriptor
s that are passed into the validator.
Descriptors passed to this filter may or may not be reified. The filter should try as much as possible to do its work without reifying the descriptor.
The filter may be run more than once on a descriptor if some condition caused the cache of results per descriptor to become invalidated.

that passed the filter is to be looked up with the API
or injected into an injection point, or on any bind or unbind operation.
