isCollectionType

public final boolean isCollectionType()
Description copied from interface: Type
Return true if the implementation is castable to CollectionType. Essentially a polymorphic version of (type instanceof CollectionType.class)

A CollectionType is additionally an AssociationType; so if this method returns true, Type.isAssociationType() should also return true.

Returns:
True if this type is also an CollectionType implementor; false otherwise.

isComponentType

public final boolean isComponentType()
Description copied from interface: Type
Return true if the implementation is castable to CompositeType. Essentially a polymorphic version of (type instanceof CompositeType.class). A component type may own collections or associations and hence must provide certain extra functionality.

Specified by:

isEntityType

public final boolean isEntityType()
Description copied from interface: Type
Return true if the implementation is castable to EntityType. Essentially a polymorphic version of (type instanceof EntityType.class).

isEntityType in interface Type
Returns:
True if this type is also an EntityType implementor; false otherwise.

isAnyType

public final boolean isAnyType()

isAnyType in interface Type
Returns:
True if this type is also an AnyType implementor; false otherwise.

isXMLElement

public final boolean isXMLElement()
Specified by:
isXMLElement in interface Type

isSame

public final boolean isSame(Object x,
                            Object y)
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
Parameters:
x - The first value
y - The second value
Returns:
True if there are considered the same (see discussion above).

                             Object y,
                             SessionFactoryImplementor factory)
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
Parameters:
x - The first value
y - The second value
factory - The session factory
Returns:
True if there are considered equal (see discussion above).

isEqual

public final boolean isEqual(Object one,
                             Object another)
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
Parameters:
one - The first value
another - The second value
Returns:
True if there are considered equal (see discussion above).

getHashCode

public final int getHashCode(Object x)
Description copied from interface: Type
Get a hash code, consistent with persistence "equality". Again for most types the normal usage is to delegate to the value's hashCode.

Specified by:
getHashCode in interface Type
Parameters:
x - The value for which to retrieve a hash code
Returns:
The hash code

getHashCode

public final int getHashCode(Object x,
                             SessionFactoryImplementor factory)

Returns:
The hash code

compare

                         Object y)
Description copied from interface: Type
Perform a Comparator style comparison between values

Specified by:
compare in interface Type
Parameters:
x - The first value
y - The second value

                             Object current,
                             SessionImplementor session)

                                boolean[] checkable,
                                SessionImplementor session)
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.SessionImplementor) 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.SessionImplementor) here/

Specified by:
isModified in interface Type
Parameters:
oldHydratedState - the database state, in a "hydrated" form, with identifiers unresolved

checkable - which columns are actually updatable
session - The session from which the request originated.
Returns:
true if the field has been modified

isMutable in interface Type
Returns:
boolean

                             SessionFactoryImplementor factory)
Description copied from interface: Type
Return a deep copy of the persistent state, stopping at entities and at collections.

Specified by:
deepCopy in interface Type
Parameters:
value - The value to be copied
factory - The session factory

                               throws HibernateException
Description copied from interface: Type
Return a disassembled representation of the object. This is the value Hibernate will use in second level caching, so care should be taken to break values down to their simplest forms; for entities especially, this means breaking them down into their constituent parts.

Specified by:
disassemble in interface Type
Parameters:
value - the value to cache
session - the originating session
owner - optional parent entity object (needed for collections)
Returns:
the disassembled, deep cloned state
Throws:
HibernateException - An error from Hibernate

                      throws HibernateException
Description copied from interface: Type
Reconstruct the object from its disassembled state. This method is the reciprocal of Type.disassemble(java.lang.Object, org.hibernate.engine.spi.SessionImplementor, java.lang.Object)

Specified by:
assemble in interface Type
Parameters:
cached - the disassembled state from the cache
session - the originating session
owner - the parent entity object
Returns:
the (re)assembled object
Throws:
HibernateException - An error from Hibernate

                                 SessionImplementor session)
Description copied from interface: Type
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
Parameters:
cached - The key
session - The originating session

hydrate

public final Object hydrate(ResultSet rs,
                            String[] names,
                            SessionImplementor session,
                            Object owner)
                     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.SessionImplementor, java.lang.Object) This hydrated value will be either:

Specified by:
hydrate in interface Type
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

Type.resolve(java.lang.Object, org.hibernate.engine.spi.SessionImplementor, java.lang.Object)

resolve

public final Object resolve(Object value,
                            SessionImplementor session,
                            Object owner)
                     throws HibernateException
Description copied from interface: Type
The second phase of 2-phase loading. Only really pertinent for entities and collections. Here we resolve the identifier to an entity or collection instance

Specified by:
resolve in interface Type
Parameters:
value - an identifier or value returned by hydrate()
session - the session
owner - the parent entity
Returns:
the given value, or the value associated with the identifier
Throws:
HibernateException - An error from Hibernate
See Also:
Type.hydrate(java.sql.ResultSet, java.lang.String[], org.hibernate.engine.spi.SessionImplementor, java.lang.Object)

semiResolve

public final Object semiResolve(Object value,
                                SessionImplementor session,
                                Object owner)
                         throws HibernateException
Description copied from interface: Type
Given a hydrated, but unresolved value, return a value that may be used to reconstruct property-ref associations.

Specified by:
semiResolve in interface Type
Parameters:
value - The unresolved, hydrated value
session - THe originating session
owner - The value owner
Returns:
The semi-resolved value
Throws:
HibernateException - An error from Hibernate

getSemiResolvedType

public final Type getSemiResolvedType(SessionFactoryImplementor factory)
Description copied from interface: Type
As part of 2-phase loading, when we perform resolving what is the resolved type for this type? Generally speaking the type and its semi-resolved type will be the same. The main deviation from this is in the case of an entity where the type would be the entity type and semi-resolved type would be its identifier type

Specified by:
getSemiResolvedType in interface Type
Parameters:
factory - The session factory
Returns:
The semi-resolved type

replace

public final Object replace(Object original,
                            Object target,
                            SessionImplementor session,
                            Object owner,
                            Map copyCache)
Description copied from interface: Type
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.

Specified by:
replace in interface Type
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
Returns:
the value to be merged

                      ForeignKeyDirection foreignKeyDirection)
Description copied from interface: Type
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.

Specified by:

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?
