DateType

public DateType()

Method Detail

get

public Object get(ResultSet rs,
                  String name)
           throws SQLException

Specified by:

get in class NullableType

Throws:

SQLException

---

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

Specified by:

set in class NullableType

Throws:

SQLException

---

sqlType

public int sqlType()

Specified by:

sqlType in class NullableType

---

equals

public boolean equals(Object x,
                      Object y)

Description copied from interface: Type

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

Specified by:

equals in interface Type

Parameters:

x -

y -

Returns:

boolean

---

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 NullableType

---

hasNiceEquals

public boolean hasNiceEquals()

Description copied from interface: Type

Does this type implement a well-behaved equals() method. (ie. one that is consistent with Type.equals().) Strictly, if this method returns true then x.equals(y) implies Type.equals(x, y) and also Type.equals(x, y) implies that probably x.equals(y)

Specified by:

hasNiceEquals in interface Type

Overrides:

hasNiceEquals in class MutableType

---

stringToObject

public Object stringToObject(String xml)
                      throws Exception

Description copied from interface: IdentifierType

Convert the value from the mapping file to a Java object.

Specified by:

stringToObject in interface IdentifierType

Parameters:

xml - the value of discriminator-value or unsaved-value attribute

Returns:

Object

Throws:

Exception

---

objectToSQLString

public String objectToSQLString(Object value)
                         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

Parameters:

value -

Returns:

String

Throws:

Exception

---

fromStringValue

public Object fromStringValue(String xml)
                       throws HibernateException

Specified by:

fromStringValue in class NullableType

Throws:

HibernateException
