Method Detail

registerExecutor

public void registerExecutor(QueryExecutor<Result,Parameters> executor)

unregisterExecutor

public void unregisterExecutor(QueryExecutor<Result,Parameters> executor)

createQuery

public final Query<Result> createQuery(Parameters parameters)

Returns:

query to perform the search. @param parameters of the search

getExecutors

protected java.util.List<QueryExecutor<Result,Parameters>> getExecutors()

hasAnyExecutors

public boolean hasAnyExecutors()

createUniqueResultsQuery

public final Query<Result> createUniqueResultsQuery(Parameters parameters)

Parameters:

parameters - of the search

Returns:

query to perform the search. Obtained results are automatically filtered wrt. equals() relation.

createUniqueResultsQuery

public final Query<Result> createUniqueResultsQuery(Parameters parameters,
                                                    <any> hashingStrategy)

Parameters:

parameters - of the search

hashingStrategy - strategy to factor results

Returns:

query to perform the search. Obtained results are automatically filtered wrt. equals() relation.

createUniqueResultsQuery

public final <T> Query<Result> createUniqueResultsQuery(Parameters parameters,
                                                        <any> hashingStrategy,
                                                        Function<? super Result,? extends T> mapper)

Parameters:

parameters - of the search

hashingStrategy - strategy to factor results

mapper - function that maps results to their mapping counterparts.

Returns:

query to perform the search. Obtained results are mapped to whatever objects that are automatically filtered wrt. equals() relation. Storing mapped objects instead of original elements may be wise wrt to memory consumption.
