Class MatrixSignalMast

  • All Implemented Interfaces:
    java.beans.VetoableChangeListener, java.lang.Comparable<NamedBean>, java.util.EventListener, PropertyChangeProvider, NamedBean, Signal, SignalMast

    public class MatrixSignalMast
    extends AbstractSignalMast
    SignalMast implemented via a Binary Matrix (Truth Table) of Apects x Turnout objects.

    A MatrixSignalMast is built up from an array of turnouts to control each aspect. System name specifies the creation information (except for the actual output beans):

     IF$xsm:basic:one-searchlight:($0001)-3t
     
    The name is a colon-separated series of terms:
    • IF$xsm - defines signal masts of this type (x for matriX)
    • basic - name of the signaling system
    • one-searchlight - name of the particular aspect map/mast model
    • ($0001) - small ordinal number for telling various matrix signal masts apart
    • name ending in -nt for (binary) Turnout outputs where n = the number of binary outputs, between 1 and mastBitNum i.e. -3t

        Store bits in aspectToOutput hashmap, synchronized.

        Length of bitArray should match the number of outputs defined, so one digit per output.

      • dispose

        public void dispose()
        Description copied from class: AbstractNamedBean
        Deactivate this object, so that it releases as many resources as possible and no longer effects others.

        For example, if this object has listeners, after a call to this method it should no longer notify those listeners. Any native or system-wide resources it maintains should be released, including threads, files, etc.

        It is an error to invoke any other methods on this object once dispose() has been called. Note, however, that there is no guarantee about behavior in that case.

        Afterwards, references to this object may still exist elsewhere, preventing its garbage collection. But it's formally dead, and shouldn't be keeping any other objects alive. Therefore, this method should null out any references to other objects that this NamedBean contained.

        Specified by:
        dispose in interface NamedBean
        Overrides:
        dispose in class AbstractNamedBean
