Constructor Detail

DBPersistenceManager

public DBPersistenceManager(AbstractTenant tenant,
                            InvalidationManager invManager)

Method Detail

getSQLTypeDef

public String getSQLTypeDef(Class javaClass,
                            String ownTypeDef)

Specified by:

getSQLTypeDef in interface PersistenceManager

Returns:

the property SQL column type definition for a given java class. ( e.g. for oracle String.class would be mapped to NVARCHAR2(2000) )

cache

protected final PersistenceInfoCache cache()

getPersistenceInfo

public final TypeInfoMap getPersistenceInfo(String code)

Returns a TypeInfoMap instance for each composed type. These instances are cached and pre-loaded on system startup. only composed types created after startup will be analyzed and a new instance is created.

If the instances could not be pre-load ( ususally when the system is not yet initialized ) TypeInfoMap.EMPTY_INFOMAP is returned.

Specified by:

getPersistenceInfo in interface PersistenceManager

Parameters:

code - the code of the item type aka composed type

getPersistenceInfo

public final TypeInfoMap getPersistenceInfo(PK typePK)

Specified by:

getPersistenceInfo in interface PersistenceManager

getInitialPersistenceInfos

public PropertyTableDefinition getInitialPersistenceInfos(ComposedTypeRemote type,
                                                          boolean reinit)

Specified by:

getInitialPersistenceInfos in interface PersistenceManager

createInitialPersistenceInfos

public final Collection<PropertyTableDefinition> createInitialPersistenceInfos(Collection types,
                                                                               boolean reinit)

should only be called during initialization! this analyzes the collection of item type and creates new TypeInfoMap instances for them. the difference to loading them via getPersistenceInfo(String) or loadPersistenceInfos() is that even property features without database column are put inside the instance, provided they have a proposed column name. this assumes that the caller of this method is able to create these columns somehow.

Specified by:

createInitialPersistenceInfos in interface PersistenceManager

Parameters:

types - the initial (non-abstract) types of the system

reinit - needed to get type manager from

Returns:

a collection of PropertyTableDefinition, one for each table

getDumpFileName

public String getDumpFileName()

restorePersistenceInfoCache

protected PersistenceInfoCache restorePersistenceInfoCache()

dumpPersistenceInfoCache

protected void dumpPersistenceInfoCache(PersistenceInfoCache pic)

reloadPersistenceInfos

public final void reloadPersistenceInfos()

loadPersistenceInfos

public final void loadPersistenceInfos()

loads persistence info for all non-abstract types of the initialized system. this has to be called before any access to items ! otherwise accessing their properties will fail.

for each type a instance is created and cached. these maps only contain features with present database column. you may use this to manually change a database column , shutdown the system, change you schema accordingly and restart the system again.

Specified by:

loadPersistenceInfos in interface PersistenceManager

cachesInfoFor

public boolean cachesInfoFor(PK typePK)

Specified by:

cachesInfoFor in interface PersistenceManager

isLoaded

public boolean isLoaded()

Specified by:

isLoaded in interface PersistenceManager

isDestroyed

public boolean isDestroyed()

isLoading

public boolean isLoading()

getAllDeployments

public Set<ItemDeployment> getAllDeployments()

getItemDeployment

public ItemDeployment getItemDeployment(String beanOrJNDIName)

Specified by:

getItemDeployment in interface PersistenceManager

Parameters:

beanOrJNDIName - the jndi or bean name to get the deployment for

Returns:

the item deployment for this bean or jndi name, null if no such deployment exists

getDuplicatedItemDeployments

public Map<Integer,ItemDeployment> getDuplicatedItemDeployments()

Description copied from interface: PersistenceManager

Returns a duplicated deployments by its type code. There is always inserted deployment which is deployed in DB persistance as to be redundant in compare to xml modeled one.

Specified by:

getDuplicatedItemDeployments in interface PersistenceManager

getItemDeployment

Specified by:

getItemDeployment in interface PersistenceManager

getAllSubDeployments

getJNDIName

public String getJNDIName(int typeCode)

Specified by:

getJNDIName in interface PersistenceManager

Parameters:

Returns:

the jndi name of the bean deployment which owns this typecode, null if no such deployment exists

getJNDIName
