Interface Memory

  • All Superinterfaces:
    java.lang.Comparable<NamedBean>, NamedBean, PropertyChangeProvider
    All Known Implementing Classes:
    AbstractMemory, DefaultMemory

    public interface Memory
    extends NamedBean
    Represent a Memory, a place to store values.

    The AbstractMemory class contains a basic implementation of the state and messaging code, and forms a useful start for a system-specific implementation.

    The states and names are Java Bean parameters, so that listeners can be registered to be notified of any changes.

    Each Memory object has a two names. The "user" name is entirely free form, and can be used for any purpose. The "system" name is provided by the system-specific implementations, and provides a unique mapping to the layout control system (for example LocoNet or NCE) and address within that system.
