public ByteArrayBlobType()

Deprecated.

Method Detail

sqlTypes

public int[] sqlTypes(Mapping mapping)

Deprecated.

Description copied from interface: Type

Return the JDBC types codes (per Types) for the columns mapped by this type.

NOTE: The number of elements in this array matches the return from Type.getColumnSpan(org.hibernate.engine.spi.Mapping).

Parameters:

mapping - The mapping object :/

Returns:

The JDBC type codes.

isEqual

public boolean isEqual(Object x,
              Object y,
              SessionFactoryImplementor factory)

Deprecated.

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

Returns:

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

getHashCode

public int getHashCode(Object x,
              SessionFactoryImplementor factory)

Deprecated.

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

Overrides:

getHashCode in class AbstractType

Parameters:

x - The value for which to retrieve a hash code

factory - The session factory

Returns:

The hash code

deepCopy

public Object deepCopy(Object value,
              SessionFactoryImplementor factory)
                throws HibernateException

Deprecated.

Description copied from interface: Type

Return a deep copy of the persistent state, stopping at entities and at collections.

Parameters:

value - The value to be copied

factory - The session factory

Returns:

The deep copy

Throws:

HibernateException - An error from Hibernate

getReturnedClass

public Class getReturnedClass()

Deprecated.

Description copied from interface: Type

The class returned by Type.nullSafeGet(java.sql.ResultSet, java.lang.String[], org.hibernate.engine.spi.SessionImplementor, java.lang.Object) methods. This is used to establish the class of an array of this type.

Returns:

The java type class handled by this type.

get

protected Object get(ResultSet rs,
         String name)
              throws SQLException

Deprecated.

Specified by:

get in class AbstractLobType

Throws:

SQLException

set

protected void set(PreparedStatement st,
       Object value,
       int index,
       SessionImplementor session)
            throws SQLException

Deprecated.

Specified by:

set in class AbstractLobType

Throws:

SQLException

setToXMLNode

public void setToXMLNode(Node node,
                Object value,
                SessionFactoryImplementor factory)
                  throws HibernateException

Deprecated.

Description copied from interface: Type

A representation of the value to be embedded in an XML element.

Parameters:

node - The XML node to which to write the value

value - The value to write

factory - The session factory

Throws:

HibernateException - An error from Hibernate

toString

public String toString(Object val)

Deprecated.

toLoggableString

public String toLoggableString(Object value,
                      SessionFactoryImplementor factory)

Deprecated.

Description copied from interface: Type

Generate a representation of the value for logging purposes.

Parameters:

value - The value to be logged

factory - The session factory

Returns:

The loggable representation

fromXMLNode

public Object fromXMLNode(Node xml,
                 Mapping factory)
                   throws HibernateException

Deprecated.

Description copied from interface: Type

Parse the XML representation of an instance.

Parameters:

xml - The XML node from which to read the value

factory - The session factory

Returns:

an instance of the mapped class

Throws:

HibernateException - An error from Hibernate

wrap

protected Object wrap(byte[] bytes)

Deprecated.

unWrap

protected byte[] unWrap(Object bytes)

Deprecated.

isMutable

public boolean isMutable()

Deprecated.

Description copied from interface: Type

Are objects of this type mutable. (With respect to the referencing object ... entities and collections are considered immutable because they manage their own internal state.)

Returns:

boolean

replace

public Object replace(Object original,
             Object target,
             SessionImplementor session,
             Object owner,
             Map copyCache)
               throws HibernateException

Deprecated.

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.

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

Throws:

HibernateException - An error from Hibernate

toColumnNullness

public boolean[] toColumnNullness(Object value,
                         Mapping mapping)

Deprecated.

Description copied from interface: Type

Given an instance of the type, return an array of boolean, indicating which mapped columns would be null.

Parameters:

value - an instance of the type

mapping - The mapping abstraction

Returns:

array indicating column nullness for a value instance
