Constructor Details

StoredProcedureQuery

public StoredProcedureQuery(JDBCStore store)

Method Details

getOperation

public int getOperation()

getProcedure

public StoredProcedure getProcedure()

getDictionary

public DBDictionary getDictionary()

setQuery

public boolean setQuery(Object meta)

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

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

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

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
