| public void | addLockValuesToTranslationRow(oracle.toplink.essentials.queryframework.ObjectLevelModifyQuery query)INTERNAL:
The method should update the translation row with the
correct write lock values. This method is called on a delete.
#see this method in VersionLockingPolicy
|
| public oracle.toplink.essentials.expressions.Expression | buildDeleteExpression(oracle.toplink.essentials.internal.helper.DatabaseTable table, oracle.toplink.essentials.expressions.Expression mainExpression, oracle.toplink.essentials.internal.sessions.AbstractRecord row)INTERNAL:
When given an expression, this method will return a new expression with
the optimistic locking values included. This expression will be used
in a delete call.
#see this method in VersionLockingPolicy
|
| public oracle.toplink.essentials.expressions.Expression | buildUpdateExpression(oracle.toplink.essentials.internal.helper.DatabaseTable table, oracle.toplink.essentials.expressions.Expression mainExpression, oracle.toplink.essentials.internal.sessions.AbstractRecord translationRow, oracle.toplink.essentials.internal.sessions.AbstractRecord modifyRow)INTERNAL:
When given an expression, this method will return a new expression with
the optimistic locking values included. This expression will be used in
an update call.

|
| public java.lang.Object | clone()
|
| public int | compareWriteLockValues(java.lang.Object value1, java.lang.Object value2)INTERNAL:
This method compares two writeLockValues.
The writeLockValues should be non-null and of the correct type.
Returns:
-1 if value1 is less (older) than value2;
0 if value1 equals value2;
1 if value1 is greater (newer) than value2.
Throws:
NullPointerException if the passed value is null;
ClassCastException if the passed value is of a wrong type.
|
| public abstract java.lang.Object | getBaseValue()INTERNAL:
This is the base value that is older than all other values, it is used in the place of
null in some situations.
|
| public java.lang.Object | getValueToPutInCache(oracle.toplink.essentials.internal.sessions.AbstractRecord row, oracle.toplink.essentials.internal.sessions.AbstractSession session)INTERNAL:
Return the value that should be stored in the identity map.
If the value is not stored in the cache, then return a null.
#see this method in VersionLockingPolicy
|
| public int | getVersionDifference(java.lang.Object currentValue, java.lang.Object domainObject, java.util.Vector primaryKeys, oracle.toplink.essentials.internal.sessions.AbstractSession session)PUBLIC:
Return the number of versions different between these objects.
|
| public oracle.toplink.essentials.internal.helper.DatabaseField | getWriteLockField()INTERNAL:
Return the write lock field.
#see this method in VersionLockingPolicy
|
| public oracle.toplink.essentials.expressions.Expression | getWriteLockUpdateExpression(oracle.toplink.essentials.expressions.ExpressionBuilder builder)INTERNAL:
This method will return an expression that is used to update its optimistic
locking field.
#see this method in VersionLockingPolicy
|
| public java.lang.Object | getWriteLockValue(java.lang.Object domainObject, java.util.Vector primaryKey, oracle.toplink.essentials.internal.sessions.AbstractSession session)INTERNAL:
This method will return the optimistic lock value for the object
#see this method in VersionLockingPolicy
|
| public void | initialize(oracle.toplink.essentials.internal.sessions.AbstractSession session)INTERNAL:
It is responsible for initializing the policy.
#see this method in VersionLockingPolicy
|
| public void | initializeProperties()INTERNAL:
Responsible for pre-initializing.

|
| public boolean | isChildWriteLockValueGreater(oracle.toplink.essentials.internal.sessions.AbstractSession session, java.util.Vector primaryKey, java.lang.Class original, oracle.toplink.essentials.internal.sessions.ObjectChangeSet changeSet)INTERNAL:
Update the parent write lock value if the changeSet's is newer
|
| public boolean | isChildWriteLockValueGreater(oracle.toplink.essentials.internal.sessions.UnitOfWorkImpl uow, java.util.Vector primaryKey, java.lang.Class original)INTERNAL:
Update the parent write lock value if the unit of works has been incremented
|
| public boolean | isNewerVersion(java.lang.Object currentValue, java.lang.Object domainObject, java.util.Vector primaryKey, oracle.toplink.essentials.internal.sessions.AbstractSession session)INTERNAL:
Returns true if the value stored with the domainObject is more recent
than the value . Returns false otherwise.
#see this method in VersionLockingPolicy
|
| public boolean | isNewerVersion(oracle.toplink.essentials.internal.sessions.AbstractRecord databaseRow, java.lang.Object domainObject, java.util.Vector primaryKey, oracle.toplink.essentials.internal.sessions.AbstractSession session)INTERNAL:
Returns true if the value stored with the domainObject is more recent
than the value in the row. Returns false otherwise.
NOTE: This method will only be called if the shouldOnlyRefreshCacheIfNewerVersion()
flag is set on descriptor.
