Interface | Description |
---|---|
QueryFunction |
Functional interface used to abstract away methods that take in a
QueryRequest and return
a SourceResponse . |
ServiceSelectionStrategy<T> |
This interface represents the strategy used by ServiceSelector instances for selecting which
service to return from a call to ServiceSelector.getService().
|
Class | Description |
---|---|
CachedSource | |
CollectionResultComparator | |
DescribableImpl |
Default implementation of the Describable interface, providing basic setter/getter methods for a
describable item's ID, title, version, organization, and description.
|
DescribableServiceMap<V extends Describable> | |
DistanceResultComparator |
Comparator for the distance (in meters) of 2
Result objects. |
FirstElementServiceSelectionStrategy<T> |
This is a basic implementation of ServiceSelectionStrategy which returns the first element from
the supplied java.util.SortedSet.
|
ListConverter |
This converter is used to allow
SortedServiceList objects to pass through for List implementations. |
MapConverter |
This converter is used to allow
DescribableServiceMap objects to pass through for Map implementations. |
MaskableImpl |
Implementation of the Maskable interface that provides methods to set the masked ID of the item
and the ID of the item if it has not yet been masked.
|
Masker |
A utility used to mask the source ID for all maskable items that have their own name (ID).
|
RelevanceResultComparator |
Comparator for the relevance of 2
Result objects. |
Requests |
Class for static request helper method
|
ResultIterable |
Class used to iterate over the
Result objects contained in a QueryResponse returned when executing a QueryRequest . |
ServiceComparator |
Comparator for OSGi
ServiceReference objects. |
ServiceReferenceListConverter |
This converter is used to allow
ServiceReferenceListConverter objects to pass through for
List implementations. |
ServiceSelector<T> |
The ServiceSelector maintains a sorted set of bound OSGi services and provides user access to
those services.
|
ServiceSelectorConverter |
This converter is used to allow
ServiceSelector objects to pass through for List implementations. |
SortedServiceList<T> |
This utility object sorts Services by their service rankings first and then breaks ties with
service ids.
|
SortedServiceReferenceList |
This utility object sorts ServiceReferences by their service rankings first and then breaks ties
with service ids.
|
SourceDescriptorComparator |
Comparator for the sourceId of 2
SourceDescriptor objects |
SourcePoller |
The SourcePoller is the scheduler of the task to poll all configured sources at a fixed interval
to determine their availability.
|
SourcePollerRunner |
The poller to check the availability of all configured sources.
|
TemporalResultComparator |
Comparator for the temporal attribute of 2
Result objects. |
Exception | Description |
---|---|
CatalogQueryException |
Exception used to wrap checked exceptions thrown by
CatalogFramework.query(ddf.catalog.operation.QueryRequest)
methods. |
