    public interface SingleColumnType<T>

extends Type

Provide convenient methods for binding and extracting values for use with `BasicType`. Most of this is copied from the (now deprecated) `NullableType`.

Glaring omission are the forms that do not take

Method Summary
`T` | `fromStringValue(String xml)`
`Object` | `get(ResultSet rs, String name, SessionImplementor session)` Get a column value from a result set, without worrying about the possibility of null values.
`T` | `nullSafeGet(ResultSet rs, String name, SessionImplementor session)` Get a column value from a result set by name.
`void` | `set(PreparedStatement st, T value, int index, SessionImplementor session)` Set a parameter value without worrying about the possibility of null values.
`int` | `sqlType()`
`String` | `toString(T value)`

Method Detail

### sqlType

    int sqlType()

### toString

    String toString(T value)
                    throws HibernateException

  Throws:
    `HibernateException`

### fromStringValue

    T fromStringValue(String xml)
                      throws HibernateException

  Throws:
    `HibernateException`

### nullSafeGet

    T nullSafeGet(ResultSet rs,
                  String name,
                  SessionImplementor session)
                  throws HibernateException,
                         SQLException

  Get a column value from a result set by name.

  Parameters:
    `rs` - The result set from which to extract the value.
    `name` - The name of the value to extract.
    `session` - The session from which the request originates
  Returns:
    The extracted value.
  Throws:
    `HibernateException` - Generally some form of mismatch error.
    `SQLException` - Indicates problem making the JDBC call(s).

### get

    Object get(ResultSet rs,
               String name,
               SessionImplementor session)
               throws HibernateException,
                      SQLException

  Get a column value from a result set, without worrying about the possibility of null values.

  Parameters:
    `rs` - The result set from which to extract the value.
    `name` - The name of the value to extract.
    `session` - The session from which the request originates
  Returns:
    The extracted value.
  Throws:
    `HibernateException` - Generally some form of mismatch error.
    `SQLException` - Indicates problem making the JDBC call(s).

### set

    void set(PreparedStatement st,
             T value,
             int index,
             SessionImplementor session)
             throws HibernateException,
                    SQLException

  Set a parameter value without worrying about the possibility of null values. Called from `Type.nullSafeSet(java.sql.PreparedStatement, java.lang.Object, int, boolean[], org.hibernate.engine.spi.SessionImplementor)` after nullness checks have been performed.

  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.
    `session` - The session from which the request originates
  Throws:
    `HibernateException` - Generally some form of mismatch error.
    `SQLException` - Indicates problem making the JDBC call(s).
