Class SingleTypeFieldManager

  • All Implemented Interfaces:
    FieldConsumer, FieldManager, FieldSupplier
    public class SingleTypeFieldManager
extends Object
implements FieldManager
    A simple field manager that stores/fetches a single field value per type in memory.

    Calls to the store methods save the value in a local field; calls to the fetch methods return the previously stored value for that type, or the "empty" default value if nothing has been stored.

    The field number arguments to each method are ignored.
