Method Detail

connector

public Connector connector()

Return the connector reference

setCatalogInfo

public void setCatalogInfo(MemoryConnector connector,
                           short access,
                           Parameter[] parameters)

Set catalog information

access_mode

public short access_mode()

Description copied from interface: CatalogBaseOperations

The read-only attribute access_mode returns the access mode of this catalog. When the access mode is READ_ONLY, the storage object incarnations obtained through storage home instances provided by this catalog are read-only.

Specified by:

access_mode in interface CatalogBaseOperations

parameters

public Parameter[] parameters()

Return parameters

find_storage_home

public StorageHomeBase find_storage_home(java.lang.String storage_home_id)
                                  throws NotFound

Description copied from interface: CatalogBaseOperations

The find_storage_home operation can be used to obtain a storage home instance. find_storage_home raises NotFound if it cannot find a storage home that matches the given storage_home_id. The format of the storage_home_id parameter is mostly implementation-defined. In the case of type-specific catalogs (declared in PSDL), the provide declarations define valid storage_home_id parameters. The find_storage_home operation also understands storage_home_id that have the form of a PSDL type id. find_storage_home looks up a PSDL-defined storage home with this type id in the catalog?s default datastore. If the storage_home_id parameter has the form ":datastore_name", where datastore_name is a string, find_storage_home returns a storage home instance for the storage home associated with java.lang.Object (Java) in this datastore.

Specified by:

find_storage_home in interface CatalogBaseOperations

Throws:

NotFound

find_by_pid

public java.lang.Object find_by_pid(byte[] the_pid)
                             throws NotFound

Description copied from interface: CatalogBaseOperations

The find_by_pid operation attempts to locate a storage object with the given PID in the storage homes provided by the target catalog.

Specified by:

find_by_pid in interface CatalogBaseOperations

Returns:

StorageObjectBase an incarnation of this storage object

Throws:

NotFound - if it cannot find a storage object with this pid.

find_ref_by_pid

public StorageObjectRef find_ref_by_pid(byte[] the_pid)
                                 throws NotFound

Specified by:

find_ref_by_pid in interface ExtendedCatalog

Throws:

NotFound

find_all

public byte[][] find_all(StorageHomeBase home)

Specified by:

find_all in interface ExtendedCatalog

iterator

public Iterator iterator(StorageHomeBase home)

Specified by:

iterator in interface ExtendedCatalog

clean

public void clean(StorageHomeBase home)

Specified by:

clean in interface ExtendedCatalog

destroy

public void destroy(StorageHomeBase home)

Specified by:

destroy in interface ExtendedCatalog

find_home_base

public abstract StorageHomeBase find_home_base(PID pid)

Returns an storage object home from its PID ( high part is only used )
