Specified by:

isComponentType in interface Type

Overrides:

isComponentType in class AbstractType

Returns:

True if this type is also a CompositeType implementor; false otherwise.

getReturnedClass

public Class getReturnedClass()

Description copied from interface: Type

Description copied from interface: Type

Compare two instances of the class mapped by this type for persistence "equality" (equality of persistent state) taking a shortcut for entity references.

For most types this should equate to an equals check on the values. For associations the implication is a bit different. For most types it is conceivable to simply delegate to Type.isEqual(java.lang.Object, java.lang.Object)

Specified by:

isSame in interface Type

Overrides:

isSame in class AbstractType

Parameters:

x - The first value

y - The second value

Returns:

True if there are considered the same (see discussion above).

                throws HibernateException

Description copied from interface: Type

Compare two instances of the class mapped by this type for persistence "equality" (equality of persistent state).

This should always equate to some form of comparison of the value's internal state. As an example, for something like a date the comparison should be based on its internal "time" state based on the specific portion it is meant to represent (timestamp, date, time).

Specified by:

isEqual in interface Type

Overrides:

isEqual in class AbstractType

Parameters:

x - The first value

y - The second value

Returns:

True if there are considered equal (see discussion above).

Throws:

HibernateException - A problem occurred performing the comparison

isEqual

public boolean isEqual(Object x,
                       Object y,

                throws HibernateException

Description copied from interface: Type

Compare two instances of the class mapped by this type for persistence "equality" (equality of persistent state).

This should always equate to some form of comparison of the value's internal state. As an example, for something like a date the comparison should be based on its internal "time" state based on the specific portion it is meant to represent (timestamp, date, time).

Specified by:

isEqual in interface Type

Overrides:

isEqual in class AbstractType

Parameters:

x - The first value

y - The second value

factory - The session factory

Description copied from interface: CompositeType

Is the given method a member of this component's class?

Specified by:

isMethodOf in interface CompositeType

Parameters:

method - The method to check

Returns:

True if the method is a member; false otherwise.

x - The value for which to retrieve a hash code

Returns:

The hash code

getHashCode

public int getHashCode(Object x,
                       SessionFactoryImplementor factory)

Overrides:

getHashCode in class AbstractType

Parameters:

x - The value for which to retrieve a hash code

factory - The session factory

Returns:

The hash code

                          boolean[] checkable,
                          SharedSessionContractImplementor session)
                   throws HibernateException

Description copied from interface: Type

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.SharedSessionContractImplementor) methods is that here we need to account for "partially" built values. This is really only an issue with association types. For most type implementations it is enough to simply delegate to Type.isDirty(java.lang.Object, java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor) here/

Specified by:

isModified in interface Type

Overrides:

isModified in class AbstractType

Parameters:

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.

Specified by:

replace in interface Type

Overrides:

replace in class AbstractType

Parameters:

original - the value from the detached entity being merged

target - the value in the managed entity

session - The originating session

owner - The owner of the value

copyCache - The cache of already copied/replaced values

foreignKeyDirection - For associations, which direction does the foreign key point?

Returns:

the value to be merged

Throws:

HibernateException - An error from Hibernate

               throws HibernateException,
                      SQLException

Description copied from interface: Type

Extract a value from the JDBC result set. This is useful for 2-phase property initialization - the second phase is a call to Type.resolve(java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor, java.lang.Object) This hydrated value will be either:

• in the case of an entity or collection type, the key
• otherwise, the value itself

Specified by:

hydrate in interface Type

Overrides:

hydrate in class AbstractType

Parameters:

rs - The JDBC result set

names - the column names making up this type value (use to read from result set)

session - The originating session

owner - the parent entity

Returns:

An entity or collection key, or an actual value.

Throws:

HibernateException - An error from Hibernate

SQLException - An error from the JDBC driver
