getName()
Returns the abbreviated name of the type.
|
Class |
getReturnedClass()
The class returned by
Type.nullSafeGet(java.sql.ResultSet, java.lang.String[], org.hibernate.engine.spi.SessionImplementor, java.lang.Object) methods. |
boolean |
isDirty(Object old,
Object current,
boolean[] checkable,
SessionImplementor session)
Should the parent be considered dirty, given both the old and current value?
|
boolean |

Are objects of this type mutable.
|
Object |
nullSafeGet(ResultSet rs,
String[] names,
SessionImplementor session,
Object owner)
Extract a value of the
mapped class from the JDBC result set. |
Object |
nullSafeGet(ResultSet rs,
String name,
SessionImplementor session,
Object owner)
Extract a value of the
mapped class from the JDBC result set. |
void |
nullSafeSet(PreparedStatement st,
Object value,
int index,
boolean[] settable,
SessionImplementor session)
Bind a value represented by an instance of the
mapped class to the JDBC prepared
statement, ignoring some columns as dictated by the 'settable' parameter. |
void |
nullSafeSet(PreparedStatement st,
Object value,
int index,
SessionImplementor session)
Bind a value represented by an instance of the
mapped class to the JDBC prepared
statement. |
Object |
replace(Object original,
Object target,
SessionImplementor session,
Object owner,
Map copyCache)
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.
|
void |
setToXMLNode(org.dom4j.Node node,
Object value,
SessionFactoryImplementor factory)
A representation of the value to be embedded in an XML element.
|
int[] |
sqlTypes(Mapping mapping)
Return the JDBC types codes (per
Types ) for the columns mapped by this type. |
boolean[] |
toColumnNullness(Object value,
Mapping mapping)
Given an instance of the type, return an array of boolean, indicating
which mapped columns would be null.
|
String |
toLoggableString(Object value,
SessionFactoryImplementor factory)
Generate a representation of the value for logging purposes.
