public RevisionTypeType()

Method Detail

getSqlType

public int getSqlType()

Description copied from interface: UserType

Return the SQL type code for the column mapped by this type. The codes are generally defined on org.hibernate.type.SqlTypes, but could be database-specific codes

Specified by:

getSqlType in interface UserType<RevisionType>

See Also:

SqlTypes

returnedClass

public Class<RevisionType> returnedClass()

Description copied from interface: UserType

The class returned by nullSafeGet().

Specified by:

returnedClass in interface UserType<RevisionType>

Returns:

Class

nullSafeGet

public RevisionType nullSafeGet(ResultSet rs,
                                int position,
                                SharedSessionContractImplementor session,
                                Object owner)
                         throws SQLException

Description copied from interface: UserType

Retrieve an instance of the mapped class from a JDBC resultset. Implementors should handle possibility of null values.

Specified by:

nullSafeGet in interface UserType<RevisionType>

Throws:

SQLException

nullSafeSet

public void nullSafeSet(PreparedStatement preparedStatement,
                        RevisionType value,
                        int index,
                        SharedSessionContractImplementor session)
                 throws HibernateException,
                        SQLException

Description copied from interface: UserType

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

Specified by:

nullSafeSet in interface UserType<RevisionType>

Throws:

HibernateException

SQLException

deepCopy

public RevisionType deepCopy(RevisionType value)
                      throws HibernateException

Description copied from interface: UserType

Return a deep copy of the persistent state, stopping at entities and at collections. It is not necessary to copy immutable objects, or null values, in which case it is safe to simply return the argument.

Specified by:

deepCopy in interface UserType<RevisionType>

Parameters:

value - the object to be cloned, which may be null

Returns:

Object a copy

Throws:

HibernateException

isMutable

public boolean isMutable()

Description copied from interface: UserType

Are objects of this type mutable?

Specified by:

isMutable in interface UserType<RevisionType>

Returns:

boolean

assemble

public RevisionType assemble(Serializable cached,
                             Object owner)
                      throws HibernateException

Description copied from interface: UserType

Reconstruct an object from the cacheable representation. At the very least this method should perform a deep copy if the type is mutable. (optional operation)

Specified by:

assemble in interface UserType<RevisionType>

Parameters:

cached - the object to be cached

owner - the owner of the cached object

Returns:

a reconstructed object from the cacheable representation

Throws:

HibernateException

disassemble

public Serializable disassemble(RevisionType value)
                         throws HibernateException

Description copied from interface: UserType

Transform the object into its cacheable representation. At the very least this method should perform a deep copy if the type is mutable. That may not be enough for some implementations, however; for example, associations must be cached as identifier values. (optional operation)

Specified by:

disassemble in interface UserType<RevisionType>

Parameters:

value - the object to be cached

Returns:

a cacheable representation of the object

Throws:

HibernateException

replace

public RevisionType replace(RevisionType original,
                            RevisionType target,
                            Object owner)
                     throws HibernateException

Description copied from interface: UserType

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. For immutable objects, or null values, it is safe to simply return the first parameter. For mutable objects, it is safe to return a copy of the first parameter. For objects with component values, it might make sense to recursively replace component values.

Specified by:

replace in interface UserType<RevisionType>

Parameters:

original - the value from the detached entity being merged

target - the value in the managed entity

Returns:

the value to be merged

Throws:

HibernateException

hashCode

public int hashCode(RevisionType x)
             throws HibernateException

Description copied from interface: UserType

Get a hashcode for the instance, consistent with persistence "equality"

Specified by:

hashCode in interface UserType<RevisionType>

Throws:

HibernateException

equals

public boolean equals(RevisionType x,
                      RevisionType y)
               throws HibernateException

Description copied from interface: UserType

Compare two instances of the class mapped by this type for persistence "equality". Equality of the persistent state.

Specified by:

equals in interface UserType<RevisionType>

Throws:

HibernateException
