Method Summary

Object
deepCopyNotNull(Object value)
Object
fromStringValue(String xml)
Object
get(ResultSet rs, String name)
Get a column value from a result set, without worrying about the possibility of null values.
int
getHashCode(Object x, EntityMode entityMode)
Get a hashcode, consistent with persistence "equality"
String
getName()
Returns the abbreviated name of the type.
Class
getReturnedClass()
The class returned by nullSafeGet() methods.
boolean
isEqual(Object x, Object y)
String
objectToSQLString(Object value, Dialect dialect)
String representation of the value, suitable for embedding in an SQL statement.
void
set(PreparedStatement st, Object value, int index)
Set a parameter value without worrying about the possibility of null values.
int
sqlType()
A convenience form of NullableType.sqlTypes(Mapping), returning just a single type value since these are explicitly dealing with single column mappings.

Method Details

deepCopyNotNull

public Object deepCopyNotNull(Object value)
Overrides:
deepCopyNotNull in interface MutableType

fromStringValue

public Object fromStringValue(String xml)
            throws HibernateException
Overrides:
fromStringValue in interface NullableType

get

public Object get(ResultSet rs,
                  String name)
            throws SQLException
Get a column value from a result set, without worrying about the possibility of null values. Called from nullSafeGet after nullness checks have been performed.
Overrides:
get in interface NullableType
Parameters:
rs - The result set from which to extract the value.
name - The name of the value to extract.
Returns:
The extracted value.

getHashCode

public int getHashCode(Object x,
                       EntityMode entityMode)
Get a hashcode, consistent with persistence "equality"
Specified by:
getHashCode in interface Type
Overrides:
getHashCode in interface AbstractType
Parameters:
x -
entityMode -

getName

public String getName()
Returns the abbreviated name of the type.
Specified by:
getName in interface Type
Returns:
String the Hibernate type name

getReturnedClass

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

isEqual

public boolean isEqual(Object x,
                       Object y)
Overrides:
isEqual in interface NullableType

objectToSQLString

public String objectToSQLString(Object value,
                                Dialect dialect)
            throws Exception
String representation of the value, suitable for embedding in an SQL statement.
Specified by:
objectToSQLString in interface LiteralType
Parameters:
value -
dialect -
Returns:
String the value, as it appears in a SQL query

set

public void set(PreparedStatement st,
                Object value,
                int index)
            throws SQLException
Set a parameter value without worrying about the possibility of null values. Called from nullSafeSet after nullness checks have been performed.
Overrides:
set in interface 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.

sqlType

public int sqlType()
A convenience form of NullableType.sqlTypes(Mapping), returning just a single type value since these are explicitly dealing with single column mappings.
Overrides:
sqlType in interface NullableType
Returns:
The java.sql.Types mapping value.

stringToObject

public Object stringToObject(String xml)
            throws Exception
Convert the value from the mapping file to a Java object.
Specified by:
stringToObject in interface IdentifierType
Parameters:
xml - the value of discriminator-value or unsaved-value attribute
Returns:
Object

toString

public String toString(Object val)
Overrides:
toString in interface NullableType
