addMapping
PUBLIC: Add a database mapping to the receiver. Perform any required initialization of both the mapping and the receiving descriptor as a result of adding the new mapping. -
validateMappingType
-
addPrimaryKeyFieldName
PUBLIC: Specify the primary key field of the descriptors table. This should be called for each field that makes up the primary key of the table. If the descriptor has many tables, this must be the primary key in the first table, if the other tables have the same primary key nothing else is required, otherwise a primary key/foreign key field mapping must be provided for each of the other tables. -
addPrimaryKeyField
public void addPrimaryKeyField(org.eclipse.persistence.internal.helper.DatabaseField field) ADVANCED: Specify the primary key field of the descriptors table. This should be called for each field that makes up the primary key of the table. This can be used for advanced field types, such as XML nodes, or to set the field type. -
addQueryKey
PUBLIC: Add a query key to the descriptor. Query keys define Java aliases to database fields. -
addTable
public void addTable(org.eclipse.persistence.internal.helper.DatabaseTable table) PUBLIC: Specify the table for the class of objects the receiver describes. This method is used if there is more than one table. -

adjustMultipleTableInsertOrder
public void adjustMultipleTableInsertOrder()INTERNAL: Adjust the order of the tables in the multipleTableInsertOrder Vector according to the FK relationship if one (or more) were previously specified.

public void alwaysConformResultsInUnitOfWork()PUBLIC: Used to set the descriptor to always conform in any unit of work query. -
alwaysRefreshCache
public void alwaysRefreshCache()PUBLIC: This method is the equivalent of callingsetShouldAlwaysRefreshCache(boolean)
with an argument oftrue
: it configures aClassDescriptor
to always refresh the cache if data is received from the database by any query.However, if a query hits the cache, data is not refreshed regardless of how this setting is configured. For example, by default, when a query for a single object based on its primary key is executed, OracleAS TopLink will first look in the cache for the object. If the object is in the cache, the cached object is returned and data is not refreshed. To avoid cache hits, use the
disableCacheHits()
method.Also note that the
UnitOfWork
will not refresh its registered objects.Use this property with caution because it can lead to poor performance and may refresh on queries when it is not desired. Normally, if you require fresh data, it is better to configure a query with
ObjectLevelReadQuery.refreshIdentityMapResult()
. To ensure that refreshes are only done when required, use this method in conjunction withonlyRefreshCacheIfNewerVersion()
.- See Also:
-
alwaysRefreshCacheOnRemote
public void alwaysRefreshCacheOnRemote()PUBLIC: This method is the equivalent of callingsetShouldAlwaysRefreshCacheOnRemote(boolean)
with an argument oftrue
: it configures aClassDescriptor
to always remotely refresh the cache if data is received from the database by any query in aRemoteSession
.However, if a query hits the cache, data is not refreshed regardless of how this setting is configured. For example, by default, when a query for a single object based on its primary key is executed, OracleAS TopLink will first look in the cache for the object. If the object is in the cache, the cached object is returned and data is not refreshed. To avoid cache hits, use the
disableCacheHitsOnRemote()
method.Also note that the
UnitOfWork
will not refresh its registered objects.Use this property with caution because it can lead to poor performance and may refresh on queries when it is not desired. Normally, if you require fresh data, it is better to configure a query with

The implementor classes can be completely unrelated in term of the database stored in distinct tables. Queries can also be done for the interface which will query each of the implementor classes. An interface descriptor cannot define any mappings as an interface is just API and not state, a interface descriptor should define the common query key of its implementors to allow querying. An interface descriptor also does not define a primary key or table or other settings. If an interface only has a single implementor (i.e. a classes public interface or remote) then an interface descriptor should not be defined for it and relationships should be to the implementor class not the interface, in this case the implementor class can add the interface through its interface policy to map queries on the interface to it. -

-
setUnitOfWorkCacheIsolationLevel
public void setUnitOfWorkCacheIsolationLevel(int unitOfWorkCacheIsolationLevel) ADVANCED: This setting configures how the session cache will be used in a unit of work. Most of the options only apply to a unit of work in an early transaction, such as a unit of work that was flushed (writeChanges), issued a modify query, or acquired a pessimistic lock.USE_SESSION_CACHE_AFTER_TRANSACTION - Objects built from new data accessed after a unit of work early transaction are stored in the session cache. This options is the most efficient as it allows the cache to be used after an early transaction. This should only be used if it is known that this class is not modified in the transaction, otherwise this could cause uncommitted data to be loaded into the session cache. ISOLATE_NEW_DATA_AFTER_TRANSACTION - Default (when using caching): Objects built from new data accessed after a unit of work early transaction are only stored in the unit of work. This still allows previously cached objects to be accessed in the unit of work after an early transaction, but ensures uncommitted data will never be put in the session cache by storing any object built from new data only in the unit of work. ISOLATE_CACHE_AFTER_TRANSACTION - After a unit of work early transaction the session cache is no longer used for this class. Objects will be directly built from the database data and only stored in the unit of work, even if previously cached. Note that this may lead to poor performance as the session cache is bypassed after an early transaction. ISOLATE_CACHE_ALWAYS - Default (when using isolated cache): The session cache will never be used for this class. Objects will be directly built from the database data and only stored in the unit of work. New objects and changes will also never be merged into the session cache. Note that this may lead to poor performance as the session cache is bypassed, however if this class is isolated or pessimistic locked and always accessed in a transaction, this can avoid having to build two copies of the object.

An interface descriptor cannot define any mappings as an interface is just API and not state, a interface descriptor should define the common query key of its implementors to allow querying. An interface descriptor also does not define a primary key or table or other settings. If an interface only has a single implementor (i.e. a classes public interface or remote) then an interface descriptor should not be defined for it and relationships should be to the implementor class not the interface, in this case the implementor class can add the interface through its interface policy to map queries on the interface to it. -
