SQLStoreQuery
public SQLStoreQuery(JDBCStore store)
- Construct a query managed by the given context.
getStore
public JDBCStore getStore()
supportsParameterDeclarations
public boolean supportsParameterDeclarations()
- Description copied from interface:
StoreQuery
- Whether this query supports declared parameters.
- Specified by:
supportsParameterDeclarations
in interface StoreQuery
- Overrides:
supportsParameterDeclarations
in class AbstractStoreQuery
supportsDataStoreExecution
public boolean supportsDataStoreExecution()
- Description copied from interface:
StoreQuery
- True if this query supports datastore execution, false if it
can only run in memory.
- Specified by:
supportsDataStoreExecution
in interface StoreQuery
- Overrides:
supportsDataStoreExecution
in class AbstractStoreQuery
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 AbstractStoreQuery
subclasses
- whether to include dependent mapped subclasses in the
results; independent subclasses should never be included
requiresCandidateType
public boolean requiresCandidateType()
- Description copied from interface:
StoreQuery
- Whether this query requires a candidate class.
- Specified by:
requiresCandidateType
in interface StoreQuery
- Overrides:
requiresCandidateType
in class AbstractStoreQuery
requiresParameterDeclarations
public boolean requiresParameterDeclarations()
- Description copied from interface:
StoreQuery
- Whether this query requires parameters to be declared.
- Specified by:
requiresParameterDeclarations
in interface StoreQuery
- Overrides:
requiresParameterDeclarations
in class AbstractStoreQuery
