Method Detail

set

public void set(PreparedStatement st,
                Object value,
                int index)
         throws HibernateException,
                SQLException
Description copied from class: NullableType
Set a parameter value without worrying about the possibility of null values. Called from NullableType.nullSafeSet(java.sql.PreparedStatement, java.lang.Object, int, boolean[], org.hibernate.engine.SessionImplementor) after nullness checks have been performed.

Specified by:
set in class NullableType
Parameters:
st - The statement into which to bind the parameter value.
value - The parameter value to bind.
index - The position or index at which to bind the param value.
Throws:
HibernateException - Generally some form of mismatch error.
SQLException - Indicates problem making the JDBC call(s).

get

public Object get(ResultSet rs,
                  String name)
           throws HibernateException,
                  SQLException
Description copied from class: NullableType
Get a column value from a result set, without worrying about the possibility of null values. Called from NullableType.nullSafeGet(java.sql.ResultSet, java.lang.String[], org.hibernate.engine.SessionImplementor, java.lang.Object) after nullness checks have been performed.

Specified by:
get in class NullableType
Parameters:
rs - The result set from which to extract the value.
name - The name of the value to extract.
Returns:
The extracted value.
Throws:
HibernateException - Generally some form of mismatch error.
SQLException - Indicates problem making the JDBC call(s).

getReturnedClass

public Class getReturnedClass()
Description copied from interface: Type
The class returned by nullSafeGet() methods. This is used to establish the class of an array of this type.

Returns:
Class

isEqual

public boolean isEqual(Object x,
                       Object y)
                throws HibernateException
Overrides:
isEqual in class NullableType
Throws:
HibernateException

getHashCode

public int getHashCode(Object x,
                       EntityMode entityMode)
Description copied from interface: Type
Get a hashcode, consistent with persistence "equality"

Specified by:
getHashCode in interface Type
Overrides:
getHashCode in class AbstractType

toString

public String toString(Object value)
                throws HibernateException
Specified by:
toString in class NullableType
Throws:
HibernateException

fromStringValue

public Object fromStringValue(String xml)
                       throws HibernateException
Specified by:
fromStringValue in class NullableType
Throws:
HibernateException

getName

public String getName()
Description copied from interface: Type
Returns the abbreviated name of the type.

Returns:
String the Hibernate type name

deepCopyNotNull

public Object deepCopyNotNull(Object value)
                       throws HibernateException
Specified by:
deepCopyNotNull in class MutableType
Throws:
HibernateException

sqlType

public int sqlType()
Description copied from class: NullableType
A convenience form of NullableType.sqlTypes(org.hibernate.engine.Mapping), returning just a single type value since these are explicitly dealing with single column mappings.

Specified by:
sqlType in class NullableType
Returns:
The Types mapping value.

assemble

public Object assemble(Serializable cached,
                       SessionImplementor session,
                       Object owner)
                throws HibernateException
Description copied from interface: Type
Reconstruct the object from its cached "disassembled" state.

Specified by:
assemble in interface Type
Overrides:
assemble in class AbstractType
Parameters:
cached - the disassembled state from the cache
session - the session
owner - the parent entity object
Returns:
the the object
Throws:
HibernateException

disassemble

public Serializable disassemble(Object value,
                                SessionImplementor session,
                                Object owner)
                         throws HibernateException
Description copied from interface: Type
Return a cacheable "disassembled" representation of the object.

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