void |
invalidateCompilation()
Invalidate any internal compilation state.
|
Object |
newCompilation()
Create a new compilation for this query.
|
Object |
newCompilationKey()
Create a new key for caching compiled query information.
|
StoreQuery.Executor |
newDataStoreExecutor(ClassMetaData meta,
boolean subs)
Return an executor for datastore execution of this query.
|
StoreQuery.Executor |
newInMemoryExecutor(ClassMetaData meta,
boolean subs)
Return an executor for in-memory execution of this query.
|
void |
populateFromCompilation(Object comp)
Populate internal data from compilation.
|
boolean |
requiresCandidateType()
Whether this query requires a candidate class.

boolean |
requiresParameterDeclarations()
Whether this query requires parameters to be declared.
|
void |
setContext(QueryContext qctx)
Set the current query context.
|
boolean |
setQuery(Object query)
This is invoked when the user or a facade creates a new query with
an object that the system does not recognize.
|
boolean |
supportsAbstractExecutors()
Return true if this query supports execution against abstract or
interface types.
|
boolean |
supportsDataStoreExecution()
True if this query supports datastore execution, false if it
can only run in memory.
|
boolean |
supportsInMemoryExecution()
True if this query supports in-memory execution, false if it
can only run against the datastore.
|
boolean |
supportsParameterDeclarations()
Whether this query supports declared parameters.
