public Object assemble(Serializable cached, SessionImplementor session, Object owner) throws HibernateException
Reconstruct the object from its cached "disassembled" state.
- Parameters:
cached
- the disassembled state from the cachesession
- the sessionowner
- the parent entity object
- Returns:
- the the object
public void beforeAssemble(Serializable cached, 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.
- Specified by:
- beforeAssemble in interface Type
public int compare(Object x, Object y, EntityMode entityMode)
compare two instances of the type
- Parameters:
entityMode
-
public Serializable disassemble(Object value, SessionImplementor session, Object owner) throws HibernateException
Return a cacheable "disassembled" representation of the object.
- Specified by:
- disassemble in interface Type
- Parameters:
value
- the value to cachesession
- the sessionowner
- optional parent entity object (needed for collections)
- Returns:
- the disassembled, deep cloned state
public int getHashCode(Object x, EntityMode entityMode)
Get a hashcode, consistent with persistence "equality"
- Specified by:
- getHashCode in interface Type
- Parameters:
x
-entityMode
-
public int getHashCode(Object x, EntityMode entityMode, SessionFactoryImplementor factory)
Get a hashcode, consistent with persistence "equality"
- Specified by:
- getHashCode in interface Type
- Parameters:
x
-entityMode
-factory
-
public Type getSemiResolvedType(SessionFactoryImplementor factory)
Get the type of a semi-resolved value.
- Specified by:
- getSemiResolvedType in interface Type
public Object hydrate(ResultSet rs, String[] names, SessionImplementor session, Object owner) throws HibernateException, SQLException
Retrieve an instance of the mapped class, or the identifier of an entity or collection, from a JDBC resultset. This is useful for 2-phase property initialization - the second phase is a call to resolveIdentifier().
- Parameters:
rs
-names
- the column namessession
- the sessionowner
- the parent entity
- Returns:
- Object an identifier or actual value
- Throws:
HibernateException
-
public boolean isAnyType()
Is this an "any" type. i.e. a reference to a persistent entity that is not modelled as a (foreign key) association.
public boolean isAssociationType()
Return true if the implementation is castable to AssociationType. This does not necessarily imply that the type actually represents an association.
- Specified by:
- isAssociationType in interface Type
- Returns:
- boolean
- See Also:
AssociationType
public boolean isCollectionType()
Is this type a collection type.
- Specified by:
- isCollectionType in interface Type
public boolean isComponentType()
Is this type a component type. If so, the implementation must be castable to AbstractComponentType. A component type may own collections or associations and hence must provide certain extra functionality.
- Specified by:
- isComponentType in interface Type
- Returns:
- boolean
- See Also:
AbstractComponentType
public boolean isDirty(Object old, Object current, SessionImplementor session) throws HibernateException
Should the parent be considered dirty, given both the old and current field or element value?
- Parameters:
old
- the old valuecurrent
- the current valuesession
-
- Returns:
- true if the field is dirty
public boolean isEntityType()
Is this type an entity type?
- Specified by:
- isEntityType in interface Type
- Returns:
- boolean
public boolean isEqual(Object x, Object y, EntityMode entityMode)
Compare two instances of the class mapped by this type for persistence "equality" - equality of persistent state.
- Parameters:
x
-y
-entityMode
-
- Returns:
- boolean
public boolean isEqual(Object x, Object y, EntityMode entityMode, SessionFactoryImplementor factory)
Compare two instances of the class mapped by this type for persistence "equality" - equality of persistent state.
- Parameters:
x
-y
-entityMode
-
- Returns:
- boolean
public boolean isModified(Object old, Object current, boolean[] checkable, SessionImplementor session) throws HibernateException
Has the parent object been modified, compared to the current database state?
- Specified by:
- isModified in interface Type
- Parameters:
checkable
- which columns are actually updatablesession
-
- Returns:
- true if the field has been modified
public boolean isSame(Object x, Object y, EntityMode entityMode) throws HibernateException
Compare two instances of the class mapped by this type for persistence "equality" - equality of persistent state - taking a shortcut for entity references.
- Parameters:
x
-y
-entityMode
-
- Returns:
- boolean
- Throws:
HibernateException
-
public Object replace(Object original, Object target, SessionImplementor session, Object owner, Map copyCache, ForeignKeyDirection foreignKeyDirection) throws HibernateException
During merge, replace the existing (target) value in the entity we are merging to with a new (original) value from the detached entity we are merging. For immutable objects, or null values, it is safe to simply return the first parameter. For mutable objects, it is safe to return a copy of the first parameter. For objects with component values, it might make sense to recursively replace component values.
- Parameters:
original
- the value from the detached entity being mergedtarget
- the value in the managed entity
- Returns:
- the value to be merged
protected static void replaceNode(Node container, Element value)
public Object resolve(Object value, SessionImplementor session, Object owner) throws HibernateException
Map identifiers to entities or collections. This is the second phase of 2-phase property initialization.
- Parameters:
value
- an identifier or value returned by hydrate()session
- the sessionowner
- the parent entity
- Returns:
- the given value, or the value associated with the identifier
- Throws:
HibernateException
-
public Object semiResolve(Object value, SessionImplementor session, Object owner) throws HibernateException
Given a hydrated, but unresolved value, return a value that may be used to reconstruct property-ref associations.
- Specified by:
- semiResolve in interface Type
