Method Detail

getCLID

CLID getCLID(java.lang.Class cls)

Provides the class id for the given class.

Parameters:

cls - The class for which the corresponding class id is needed.

Returns:

CLID for the given class, or null if there is no metadata for that class.

put

void put(java.lang.Class cls,
         CLID clid)

Add a mapping from ClassMetaData to CLID.

bind

OID bind(java.lang.Class cls,
         int type,
         javax.jdo.spi.PersistenceCapable pc,
         java.lang.Object oid,
         PersistenceManagerInternal pm,
         FOStorePMF pmf)

Causes the given class mapped to an OID.

Parameters:

cls - Class to be mapped.

type - JDOIdentityType as an int.

pc - PersistenceCapable instance to copy fields from if available.

oid - Object Id instance to copy fields from if available.

pm - PersistenceManagerInternal that requested the operation.

pmf - FOStorePMF that requested the operation.

Returns:

ObjectId corresponding to given class.

updateCLID

void updateCLID(CLID pCLID,
                CLID rCLID)

Changes the class id by which this metadata is known.

Parameters:

pCLID - The class id by which the class was previously known.

rCLID - The class id by which the class should be known from now on in this JVM.

getClass

java.lang.Class getClass(CLID clid)

Return the class corresponding to the given CLID.

Parameters:

clid - The CLID for which a class is wanted.

Returns:

The java.lang.Class corresponding to the given CLID, or null if none is found.

getEntry

java.util.Map.Entry getEntry(CLID clid)

getJDOClass

JDOClass getJDOClass(java.lang.Class c)

Parameters:

c - Class whose corresponding JDOClass is needed.

Returns:

The JDOClass for the given class.

getTranscriber

FOStoreTranscriber getTranscriber(java.lang.Class c,
                                  int fieldNum)

Provides a transcriber for the field in the given JDOClass indicated by fieldNum.

Parameters:

c - JDOClass for which a transcriber is needed.

fieldNum - The absolute fieldNumber in the class modeled by jdoClass that is to be transcribed.

Returns:

a FOStoreTranscriber appropriate for the type of field in the class modeled by field fieldNum in the class corresponding to jdoClass.
