Annotation Type Index
This annotation controls whether or not fields are indexed in the datastore.
When placed on a simple field, the field will be indexed if possible. Text, Blob, and @Serialize fields cannot be indexed. If the field is an @Embed class or a collection of @Embed classes, the fields of those classes will be indexed as if the class had the @Index annotation.
When placed on an entity class or an embedded class, this sets the default for all fields to be indexed. It can be overridden by field level annotations.
If an embedded class field is annotated with @Index, any @Index or @Unindex annotation on the class itself is ignored.
If passed one or more classes that implement the If
interface, the
value will be indexed only if it tests positive for any of the conditions. This
allows "partial indexing" of only some categories of values (ie, true but not false).
