Constructor Summary

SerializableType(Class serializableClass)

 

Method Summary
Object	assemble(Serializable cached, SessionImplementor session, Object owner)           Reconstruct the object from its cached "disassembled" state.
Object	deepCopyNotNull(Object value)
Serializable	disassemble(Object value, SessionImplementor session, Object owner)           Return a cacheable "disassembled" representation of the object.
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)
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(org.hibernate.engine.Mapping), returning just a single type value since these are explicitly dealing with single column mappings.
String	toString(Object value)

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:

SQLException - Indicates problem making the JDBC call(s).

HibernateException - Generally some form of mismatch error.

---

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:

SQLException - Indicates problem making the JDBC call(s).

HibernateException - Generally some form of mismatch error.

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:

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,
