Provides utility classes for the Catalog.

Class	Description
CaseInsensitiveIfStringComparator	Comparator that ignores case for string attributes or falls back to the passed in comparator
CatalogQueryException	Exception used to wrap checked exceptions thrown by CatalogFramework.query(ddf.catalog.operation.QueryRequest) methods.
CollectionResultComparator
DescribableImpl	Default implementation of the Describable interface, providing basic setter/getter methods for a describable item's ID, title, version, organization, and description.
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.
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).

ServiceReferenceListConverter	This converter is used to allow ServiceReferenceListConverter objects to pass through for List implementations.
ServiceSelectionStrategy<T>	This interface represents the strategy used by ServiceSelector instances for selecting which service to return from a call to ServiceSelector.getService().
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.
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
TemporalResultComparator	Comparator for the temporal attribute of 2 Result objects.
