Constructor Detail

### ImmutableValueHandler

    public ImmutableValueHandler()

Method Detail

### getInstance

    public static ImmutableValueHandler getInstance()

  Singleton instance.

### map

    public Column[] map(ValueMapping vm,
                        String name,
                        ColumnIO io,
                        boolean adapt)

  Deprecated.

  Description copied from interface: `ValueHandler`
  Map the given value and return all mapped columns, or simply return an array of unmapped default columns. The columns should have at least their `Name` and `JavaType` properties set.

    `name` - use as a base to form column name(s); the column names of unmapped columns will automatically be made to fit database limitations
    `io` - I/O information about mapped columns; you do not have to set this information if returning templates
    `adapt` - whether to adapt the mapping or schema

### map

    public Column[] map(ValueMapping vm,
                        DBIdentifier name,
                        ColumnIO io,
                        boolean adapt)

### isVersionable

    public boolean isVersionable(ValueMapping vm)

  Description copied from interface: `ValueHandler`
  Return whether the values managed by this handler can be used in state image versioning.

  Specified by:
    `isVersionable` in interface `ValueHandler`
  Overrides:
    `isVersionable` in class `AbstractValueHandler`

### toDataStoreValue

    public Object toDataStoreValue(ValueMapping vm,
                                   Object val,
                                   JDBCStore store)

  Description copied from interface: `ValueHandler`
  Translate the given value to its datastore equivalent. If this value occupies multiple columns, return an object array with one element per column. For relation id columns, return the state manager the column depends on.

  Specified by:
    `toDataStoreValue` in interface `ValueHandler`
  Overrides:
    `toDataStoreValue` in class `AbstractValueHandler`
