A value is anything that is persisted by value, instead of by reference. It is essentially a Hibernate Type, together with zero or more columns. Values are wrapped by things with higher level semantics, for example properties, collections, classes.

Method Detail

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

getColumnIterator
```
@Deprecated(since="6.0")
Iterator<Selectable> getColumnIterator()
```
Deprecated.
moving away from the use of Iterator as a return type

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

getColumns
```

If the mapping involves only columns, return them.

Throws:

AssertionFailure - if the mapping involves formulas

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

```
default List<Column> getConstraintColumns()
```
Same as getColumns() except it returns the PK for the non-owning side of a one-to-one association.

Throws:

AssertionFailure - if the mapping involves formulas
