Description copied from interface: Type

Should the parent be considered dirty, given both the old and current field or element value?

Specified by:

isDirty in interface Type

Specified by:

isEqual in interface Type

Overrides:

isEqual in class AbstractType

Returns:

boolean

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

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

getColumnSpan

public int getColumnSpan(Mapping mapping)
                  throws MappingException

                       throws SQLException

Throws:

SQLException

public Object nullSafeGet(ResultSet rs,
                          String[] names,
                          SessionImplementor session,
                          Object owner)

nullSafeGet

public Object nullSafeGet(ResultSet rs,
                          String name,
                          SessionImplementor session,
                          Object owner)
                   throws HibernateException,
                          SQLException

Description copied from interface: Type

Retrieve an instance of the mapped class from a JDBC resultset. Implementations should handle possibility of null values. This method might be called if the type is known to be a single-column type.

Specified by:

nullSafeGet in interface Type

name - the column name

owner - the parent entity

Returns:

Object

Throws:

HibernateException

SQLException

nullSafeSet

public void nullSafeSet(PreparedStatement st,
                        Object value,

                        SQLException

Description copied from interface: Type

Write an instance of the mapped class to a prepared statement, ignoring some columns. Implementors should handle possibility of null values. A multi-column type should be written to parameters starting from index.

Specified by:

nullSafeSet in interface Type

value - the object to write

index - statement parameter index

settable - an array indicating which columns to ignore

Throws:

HibernateException

SQLException

set
