All known Subclasses:   org.geotools.caching.quatree.QuadTreeQueryTracker,  org.geotools.caching.quatree.QuadTreeFeatureCache,  org.geotools.caching.impl.SpatialQueryTracker,
QueryTracker
public interface QueryTracker (Code)
Records information about queries, in order to be able to tell to a DataCache if the data requested are already known, or else what data should be asked for to the source DataStore. Actual implementation should allow query-specific optimization.
author:
   Christophe Rousson, SoC 2007, CRG-ULAVAL




Method Summary
abstract public  voidclear()
     Forget every query ever registered.
abstract public  Filtermatch(Filter f)
     Restrict the Filter f to a new filter that will yield only the complementary set of data the cache doesn't hold.
abstract public  Querymatch(Query q)
     Restrict the Query q to a new query that will yield only the complementary set of data the cache doesn't hold.
abstract public  voidregister(Query q)
     Take notice that the data for the query q have been retrieved once.
abstract public  voidregister(Filter f)
     Take notice that the data for the Filter f have been retrieved once.
abstract public  voidunregister(Query q)
     Forget about the query q.
abstract public  voidunregister(Filter f)
     Forget about the filter f.



Method Detail
clear
abstract public void clear()(Code)
Forget every query ever registered. Blank mind for new days !



match
abstract public Filter match(Filter f)(Code)
Restrict the Filter f to a new filter that will yield only the complementary set of data the cache doesn't hold. If all data are known, implementation should return Filter.EXCLUDE which is a filter that yields nothing.
Parameters:
  f - the filter to restrict a restricted filter, or otherwise the input filter



match
abstract public Query match(Query q)(Code)
Restrict the Query q to a new query that will yield only the complementary set of data the cache doesn't hold. If all data are known, implementation should return new DefaultQuery(q.getTypeName(), Filter.EXCLUDE) which is a query that yields nothing.
Parameters:
  q - the query to restrict a restricted query, or otherwise the input query



register
abstract public void register(Query q)(Code)
Take notice that the data for the query q have been retrieved once. So they should be in the cache.
Parameters:
  q - the Query to register



register
abstract public void register(Filter f)(Code)
Take notice that the data for the Filter f have been retrieved once. So they should be in the cache.
Parameters:
  f - the Filter to register



unregister
abstract public void unregister(Query q)(Code)
Forget about the query q. When this query will be issued again, or a related query, the cache will have to get data from the source DataStore. This is used when the cache has reached its maximum capacity, and needs to make room for new features. For example, the input query can be the extent (bbox) of the deleted feature in the cache.
Parameters:
  q - the query to forget about.



unregister
abstract public void unregister(Filter f)(Code)
Forget about the filter f. When this filter will be used again, or a related query, the cache will have to get data from the source DataStore. This is used when the cache has reached its maximum capacity, and needs to make room for new features. For example, the input filter can be the extent (bbox) of the deleted feature in the cache.
Parameters:
  q - the query to forget about.
