Returns:
The number of columns
Throws:
MappingException - Generally indicates an issue accessing the passed mapping object.

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:

Overrides:
isComponentType in class AbstractType
Returns:
True if this type is also an CompositeType implementor; false otherwise.

getReturnedClass

public Class getReturnedClass()
Description copied from interface: Type
The class returned by Type.nullSafeGet(java.sql.ResultSet, java.lang.String[], org.hibernate.engine.SessionImplementor, java.lang.Object) methods. This is used to establish the class of an array of this type.

Specified by:

Returns:
The java type class handled by this type.

isSame

public boolean isSame(Object x,
                      Object y,
                      EntityMode entityMode)
               throws HibernateException
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 #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, org.hibernate.EntityMode)

Specified by:
isSame in interface Type
Overrides:
isSame in class AbstractType
Parameters:
x - The first value
y - The second value
entityMode - The entity mode of the values.
Returns:
True if there are considered the same (see discussion above).
Throws:
HibernateException - A problem occurred performing the comparison

                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
entityMode - The entity mode of the values.
Returns:
True if there are considered equal (see discussion above).
Throws:
HibernateException - A problem occurred performing the comparison

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:

Perform a Comparator style comparison between values

Specified by:
compare in interface Type
Overrides:
compare in class AbstractType
Parameters:
x - The first value

getHashCode

public int getHashCode(Object x,
                       EntityMode entityMode)

                       boolean[] checkable,
                       SessionImplementor session)
                throws HibernateException

                   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.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.SessionImplementor) here/

Specified by:
isModified in interface Type
Overrides:
isModified in class AbstractType
Parameters:
old - the database state, in a "hydrated" form, with identifiers unresolved
current - the current state of the object
checkable - which columns are actually updatable
session - The session from which the request originated.
Returns:
true if the field has been modified
