AbstractCharArrayType

public AbstractCharArrayType()
Method Detail

toExternalFormat

protected abstract Object toExternalFormat(char[] chars)
Convert the char[] into the expected object type


toInternalFormat

protected abstract char[] toInternalFormat(Object chars)
Convert the object into the internal char[] representation


get

public Object get(ResultSet rs,
                  String name)
           throws 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:
SQLException - Indicates problem making the JDBC call(s).

getReturnedClass

public abstract 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.

Returns:
Class

set

public void set(PreparedStatement st,
                Object value,
                int index)
         throws 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:
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.

objectToSQLString

public String objectToSQLString(Object value,
                                Dialect dialect)
                         throws Exception
Throws:
Exception

stringToObject

public Object stringToObject(String xml)
                      throws Exception
Throws:
Exception

toString

public String toString(Object value)
Specified by:
toString in class NullableType

fromStringValue

public Object fromStringValue(String xml)
Specified by:
fromStringValue in class NullableType

deepCopyNotNull

protected Object deepCopyNotNull(Object value)
                          throws HibernateException
Specified by:
deepCopyNotNull in class MutableType
Throws:
HibernateException
