Method Detail

newDataStoreExecutor

public StoreQuery.Executor newDataStoreExecutor(ClassMetaData meta,
                                       boolean subclasses)

Description copied from interface: StoreQuery

Return an executor for datastore execution of this query. Executors must be cachable and thread safe. If this class returns true from StoreQuery.supportsAbstractExecutors(), the given metadata will always be for the candidate class of this query, or possibly null if the candidate class is not itself persistence capable (like an interface or abstract base class). Otherwise, the given type will be a mapped class.

Specified by:

newDataStoreExecutor in interface StoreQuery

Overrides:

newDataStoreExecutor in class SQLStoreQuery

subclasses - whether to include dependent mapped subclasses in the results; independent subclasses should never be included

setQuery

public boolean setQuery(Object query)

Description copied from interface: StoreQuery

This is invoked when the user or a facade creates a new query with an object that the system does not recognize. Return true if the object is recognized by the store, false otherwise.

Specified by:

setQuery in interface StoreQuery

Overrides:

setQuery in class AbstractStoreQuery
