BindableId (ebean 12.3.3 API)

All Superinterfaces:

Bindable

All Known Implementing Classes:

BindableIdEmpty, BindableIdScalar
```
public interface BindableId
extends Bindable
```
Adds support for id creation for concatenated ids on intersection tables.
Specifically if the concatenated id object is null on insert this can be built from the matching ManyToOne associated beans. For example RoleUserId embeddedId object could be built from the associated Role and User beans.

This is only attempted if the id is null when it gets to the insert.

- Method Detail
  - isEmpty
```
boolean isEmpty()
```
    Return true if there is no Id properties at all.
  - isConcatenated
```
boolean isConcatenated()
```
    Return true if this is a concatenated key.
  - getIdentityColumn
```
String getIdentityColumn()
```
    Return the DB Column to use with genGeneratedKeys.
  - deriveConcatenatedId
```
boolean deriveConcatenatedId(PersistRequestBean<?> persist)
```
    Create the concatenated id for inserts with PFK relationships.
    Really only where there are ManyToOne assoc beans that make up the primary key and the values can be got from those.
