Method Detail

get

public Object get(ResultSet rs,
                  String name)
           throws 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:
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.

Specified by:
getReturnedClass in interface Type
Returns:
Class

set

public void set(PreparedStatement st,
                Object value,
                int index)
         throws 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:
SQLException - Indicates problem making the JDBC call(s).

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.

getName

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

Specified by:
getName in interface Type
Returns:
String the Hibernate type name

toString

public String toString(Object val)
Specified by:
toString in class NullableType

deepCopyNotNull

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

isEqual

public boolean isEqual(Object x,
                       Object y)
Description copied from interface: VersionType
Are the two version values considered equal?

Specified by:
isEqual in interface VersionType
Overrides:
isEqual in class NullableType
Parameters:
x - One value to check.
y - The other value to check.
Returns:
true if the values are equal, false otherwise.

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

next

public Object next(Object current,
                   SessionImplementor session)
Description copied from interface: VersionType
Increment the version.

Specified by:
next in interface VersionType
Parameters:
current - the current version
session - The session from which this request originates.
Returns:
an instance of the type

seed

public Object seed(SessionImplementor session)
Description copied from interface: VersionType
Generate an initial version.

Specified by:
seed in interface VersionType
Parameters:
session - The session from which this request originates.
Returns:
an instance of the type

getComparator

public Comparator getComparator()
Description copied from interface: VersionType
Get a comparator for version values.

Specified by:
getComparator in interface VersionType
Returns:
The comparator to use to compare different version values.

objectToSQLString

public String objectToSQLString(Object value,
                                Dialect dialect)
                         throws Exception
Description copied from interface: LiteralType
String representation of the value, suitable for embedding in an SQL statement.

Specified by:
objectToSQLString in interface LiteralType
Returns:
String the value, as it appears in a SQL query
Throws:
Exception

fromStringValue

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