## org.hibernate.metamodel.source.binder
Interface DiscriminatorSource

All Known Implementing Classes:
  DiscriminatorSourceImpl

    public interface DiscriminatorSource

Contract for sources of information about a mapped discriminator.

Method Summary
`RelationalValueSource` | `getDiscriminatorRelationalValueSource()` Obtain the column/formula information about the discriminator.
`String` | `getExplicitHibernateTypeName()` Obtain the discriminator type.
`boolean` | `isForced()` "Forces" Hibernate to specify the allowed discriminator values, even when retrieving all instances of the root class.
`boolean` | `isInserted()` Set this to `false`, if your discriminator column is also part of a mapped composite identifier.

Method Detail

### getDiscriminatorRelationalValueSource

    RelationalValueSource getDiscriminatorRelationalValueSource()

  Obtain the column/formula information about the discriminator.

  Returns:
    The column/formula information

### getExplicitHibernateTypeName

    String getExplicitHibernateTypeName()

  Obtain the discriminator type. Unlike the type of attributes, implementors here should generally specify the type in case of no user selection rather than return null because we cannot infer it from any physical java member.

  Returns:
    The discriminator type

### isForced

    boolean isForced()

  "Forces" Hibernate to specify the allowed discriminator values, even when retrieving all instances of the root class.

  Returns:
    `true` in case the discriminator value should be forces, `false` otherwise. Default is `false`.

### isInserted

    boolean isInserted()

  Set this to `false`, if your discriminator column is also part of a mapped composite identifier. It tells Hibernate not to include the column in SQL INSERTs.

  Returns:
    `true` in case the discriminator value should be included in inserts, `false` otherwise. Default is `true`.
