Method Summary | |
---|---|
Object |
assemble(Serializable oid,
SessionImplementor session,
Object owner)
Reconstruct the object from its cached "disassembled" state. |
void |
beforeAssemble(Serializable oid,
SessionImplementor session)
Called before assembling a query result set from the query cache, to allow batch fetching of entities missing from the second-level cache. |
Serializable |
disassemble(Object value,
SessionImplementor session,
Object owner)
Return a cacheable "disassembled" representation of the object. |
int |
getColumnSpan(Mapping mapping)
How many columns are used to persist this type. |
ForeignKeyDirection |
getForeignKeyDirection()
Get the foreign key directionality of this association |
Object |
hydrate(ResultSet rs,
String[] names,
SessionImplementor session,
Object owner)
Retrieve an instance of the mapped class, or the identifier of an entity or collection, from a JDBC resultset. |
boolean |
isAlwaysDirtyChecked()
Do we dirty check this association, even when there are no columns to be updated? |
boolean |
isDirty(Object old,
Object current,
boolean[] checkable,
SessionImplementor session)
Should the parent be considered dirty, given both the old and current field or element value? |
boolean |
isDirty(Object old,
Object current,
SessionImplementor session)
Should the parent be considered dirty, given both the old and current field or element value? |
boolean |
isLogicalOneToOne()
Is the association modeled here a 1-1 according to the logical moidel? |
boolean |
isModified(Object old,
Object current,
boolean[] checkable,
SessionImplementor session)
Has the parent object been modified, compared to the current database state? |
protected boolean |
isNullable()
|
boolean |
isOneToOne()
Is the association modeled here defined as a 1-1 in the database (physical model)? |
void |
nullSafeSet(PreparedStatement st,
Object value,
int index,
boolean[] settable,
SessionImplementor session)
Write an instance of the mapped class to a prepared statement, ignoring some columns. |
void |
nullSafeSet(PreparedStatement st,
Object value,
int index,
SessionImplementor session)
Write an instance of the mapped class to a prepared statement. |
int[] |
sqlTypes(Mapping mapping)
Return the SQL type codes for the columns mapped by this type. |
boolean[] |
toColumnNullness(Object value,
Mapping mapping)
Given an instance of the type, return an array of boolean, indicating which mapped columns would be null. |
boolean |
useLHSPrimaryKey()
Is the primary key of the owning entity table to be used in the join? |
