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).
