Method Detail

initialize

public void initialize(RDBMSStoreManager storeMgr,
              String type)

Description copied from class: JavaTypeMapping

Initialise this JavaTypeMapping with the given StoreManager for the given type. Used when the mapping is for a parameter in a query. This will not set the "mmd" and "datastoreContainer" parameters. If these are required for usage of the mapping then you should call "setFieldInformation(AbstractMemberMetaData, DatastoreContainerObject)" below Subclasses should override this method to perform any datastore initialization operations.

Overrides:

initialize in class TypeConverterMapping

Parameters:

storeMgr - The Datastore Adapter that this Mapping should use.

type - The Class that this mapping maps to the database.

initialize

public void initialize(org.datanucleus.metadata.AbstractMemberMetaData mmd,
              Table table,
              org.datanucleus.ClassLoaderResolver clr)

Description copied from class: SingleFieldMapping

Initialize this JavaTypeMapping with the given DatastoreAdapter for the given FieldMetaData.

Overrides:

initialize in class TypeConverterMapping

Parameters:

mmd - FieldMetaData for the field to be mapped (if any)

table - The datastore container storing this mapping (if any)

clr - the ClassLoaderResolver

initialize

public void initialize(org.datanucleus.metadata.AbstractMemberMetaData mmd,
              Table table,
              org.datanucleus.ClassLoaderResolver clr,
              org.datanucleus.store.types.converters.TypeConverter conv)

Overrides:

initialize in class TypeConverterMapping

getJavaTypeForDatastoreMapping

public String getJavaTypeForDatastoreMapping(int index)

Accessor for the name of the java-type actually used when mapping the particular datastore field. This java-type must have an entry in the datastore mappings.

Overrides:

getJavaTypeForDatastoreMapping in class TypeConverterMapping

Parameters:

index - requested datastore field index.

Returns:

the name of java-type for the requested datastore field.
