- Method Detail
  - isPrimaryKey
```
boolean isPrimaryKey()
```
    Whether this unique key is the primary key
  - getKeyColumns
```
List<ColumnDefinition> getKeyColumns()
```
    The list of columns making up the primary key.
  - getForeignKeys
```
List<ForeignKeyDefinition> getForeignKeys()
```
    The foreign keys referencing this primary key
  - resolveReferencedKey
```
UniqueKeyDefinition resolveReferencedKey()
```
    Resolve a referenced key.
    If this key coincides with a foreign key, resolve that foreign key recursively. In case of ambiguity (two foreign keys coinciding with a single unique key), this returns null.
