BigIntegerType()

Method Summary

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)
String	objectToSQLString(Object value, Dialect dialect) String representation of the value, suitable for embedding in an SQL statement.
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.
Object	stringToObject(String xml) Convert the value from the mapping file to a Java object.
String	toString(Object value)

Method Detail

objectToSQLString

public String objectToSQLString(Object value,
                                Dialect dialect)
                         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

Returns:

String the value, as it appears in a SQL query

Throws:

Exception

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

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:

HibernateException - Generally some form of mismatch error.

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

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:

HibernateException - Generally some form of mismatch error.

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

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.

toString

public String toString(Object value)
                throws HibernateException

Specified by:

toString in class NullableType

Throws:

HibernateException

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

isEqual

public boolean isEqual(Object x,
                       Object y)

Overrides:

isEqual in class NullableType

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

fromStringValue

public Object fromStringValue(String xml)

Specified by:

fromStringValue in class NullableType
