public abstract boolean autoGenerate

The auto-generate property defines how a unique ID is generated. By default, the auto-generate is false, indicating that a unique ID will be generated from the annotated field's supplied value's toString(). This field can be of any type, but it's value's string representation enforces uniqueness.

When auto-generate is true, it indicates that a unique ID will be generated by the space (when first written) injecting the UID String value into this field - which must be of type String.

Default:

false
