public interfaceValueextendsSerializable
```
A mapping model object which represents something that's persisted "by value", instead of "by reference", that is, anything with no primary key.
AValue is essentially a HibernateType, together with zero or morecolumns. In the mapping model, aValue always comes wrapped in something with higher-level semantics, for example, a property, a collection, or a class.

Method Detail

getColumnSpan
```
int getColumnSpan()
```
The number of columns and formulas in the mapping.

getSelectables
```
List<Selectable> getSelectables()
```
The mapping to columns and formulas.

getColumns
```
List<Column> getColumns()
```
If the mapping involves only columns, return them.
Throws:
AssertionFailure - if the mapping involves formulas

getVirtualSelectables
```
default List<Selectable> getVirtualSelectables()
```
Same asgetSelectables() except it returns the PK for the non-owning side of a one-to-one association.

getConstraintColumns
```
default List<Column> getConstraintColumns()
```
Same asgetColumns() except it returns the PK for the non-owning side of a one-to-one association.
Throws:
AssertionFailure - if the mapping involves formulas

Checks if this value contains any duplicate column. A column is considered duplicate when itsname is already contained in thedistinctColumn set.
If a duplicate column is found, aMappingException is thrown.
Parameters:
distinctColumns - set containing the names of the columns to check
owner - the owner of this value, used just for error reporting
