Method Summary
protected  Object	deepCopyNotNull(Object value)
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.
abstract  Class	getReturnedClass()           The class returned by nullSafeGet() methods.
String	objectToSQLString(Object value, Dialect dialect)
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.

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.

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:
