Example 26 with DccLocoAddress

use of jmri.DccLocoAddress in project JMRI by JMRI.

the class LocoNetConsistManager method requestUpdateFromLayout.

/* request an update from the layout, loading
     * Consists from the command station.
     *
     * On a LocoNet command station, the consists are stored in the
     * slots in an array based tree.  Each node in a consist contains
     * a pointer to the "top" slot in the consist.  A top slot is
     * allowed to be a member of another consist.  When this occurs,
     * it is labeled as a "mid" locomotive.
     *
     * This function updates the list of consists by scanning the
     * slots and adding new "top" slot addresses and removing address
     * that are no longer "top" locomotives.
