Method Detail

getId

long getId()

Returns the unique id of this Entity. Id's are garbage collected over time so they are only guaranteed to be unique during a specific time span: if the Entity is deleted, it's likely that a new Entity at some point will get the old id. Note: this makes Entity id's brittle as public APIs.

Returns:

The id of this Entity.
