@Contract public interface ValidationService
An implementation of ValidationService must be in the Singleton scope.
Implementations of ValidationService will be instantiated as soon as
they are added to HK2 in order to avoid deadlocks and circular references.
Therefore it is recommended that implementations of ValidationService
make liberal use of Provider
or IterableProvider
when injecting dependent services so that these services are not instantiated
when the ValidationService is created
Modifier and Type | Method and Description |
---|---|
Filter |
getLookupFilter()
This filter will be run at least once per descriptor at the point that the descriptor
is being looked up, either with the
ServiceLocator API or due to
an @Inject resolution. |
Validator |
getValidator()
Returns the
Validator that will be run whenever
a Descriptor 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. |
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.
Descriptor
is looked upValidator getValidator()
Validator
that will be run whenever
a Descriptor
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.
If this method returns false then the operation will not proceed.Copyright © 2009-2017, Oracle and/or its affiliates. All Rights Reserved.
