Method Detail

• java.lang.Class<?> getDefaultIdentityType()

  The identity type injected into an entity mapped with this implementation when the entity does not declare an id of its own, and the build has opted into native identity types with grails { gorm { defaultIdType = 'native' }}.

  Defaults to Long, which is what every entity is given when the build has not opted in. An implementation whose stores generate identifiers of another type overrides this - GORM for MongoDB returns String, because a Mongo ObjectId is generated for a String id and handed back as its hexadecimal form, with no sequence collection involved.

  Returns:

  the default identity type, never null
