ManyToOneType(TypeFactory.TypeScope scope,
String referencedEntityName)
Creates a many-to-one association type with the given referenced entity.

Modifier and Type | Method and Description |
---|---|
Object |
assemble(Serializable oid,
SessionImplementor session,
Object owner)
Reconstruct the object from its 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.
|
Size[] |
defaultSizes(Mapping mapping)
Defines the column sizes to use according to this type if the user did not explicitly say (and if no
Type.dictatedSizes(org.hibernate.engine.spi.Mapping) were given). |
Size[] |
dictatedSizes(Mapping mapping)
Return the column sizes dictated by this type.
|
Serializable |
disassemble(Object value,
SessionImplementor session,
Object owner)
Return a 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)
Extract a value from the JDBC result set.
|
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 value?
|
boolean |
isDirty(Object old,
Object current,
SessionImplementor session)
Should the parent be considered dirty, given both the old and current 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 value been modified compared to the current database state? The difference between this
and the
Type.isDirty(java.lang.Object, java.lang.Object, org.hibernate.engine.spi.SessionImplementor) methods is that here we need to account for "partially" built values. |
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)
Bind a value represented by an instance of the
mapped class to the JDBC prepared
statement, ignoring some columns as dictated by the 'settable' parameter. |
void |
nullSafeSet(PreparedStatement st,
Object value,
int index,
SessionImplementor session)
Bind a value represented by an instance of the
mapped class to the JDBC prepared
statement. |
int[] |
sqlTypes(Mapping mapping)
Return the JDBC types codes (per
Types ) 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?
