Specification - Elements
This site of the specification describes the different used elements.
Basically, all elements should use "getter" and "setter" for the
properties.
Properties, all elements have
ID
The ID is a unique number in the system, that identifies an element
independent of the type.
Name
The name of an element is a unique String in the system and is used
for identifying the element too. Additionally, the name is used in the
configuration files to get cross-connections (e.g. for routes).
Label
The label is used for display purposes only. It does not have to be unique.
The label is not used for referencing purposes.
Specific element-dependent properties
Turnouts
- Selected orientation
- Actual orientation
- Indicator, if turnout changes position
- Lock
- Trafficability lock
- Indicator, if a trafficability lock is projected
- Explaination text for the lock
- Indicator, if explaination text is set
- Indicator, if track is free or occupied
- Indicator, if a route over the turnout is selected
- Indicator, if a route over the turnout is fixed
- Type of the route
- Reference to the route
- Indicator, if local operation is allowed
- Indicator, if turnout is part of a diamond crossing with slips
- Number of axles on the track
- Indicator, if a hardware feedback exists
Double diamond crossing with slips
- Reference to left turnout
- Reference to right turnout
Single diamond crossing with slips
- Reference to left turnout
- Reference to right turnout
- Forbidden orientation of the left turnout
- Forbidden orientation of the right turnout
The combination of the forbidden positions of the two turnouts
are used to calculate the way, witch is not possible.
Diamond crossing
- Lock
- Trafficability lock
- Indicator, if a trafficability lock is projected
- Explaination text for the lock
- Indicator, if a explaination text is set
- Indicator, if the track is free or occupied
- Indicator, if a route over the element is selected
- Indicator, if a route over the element is fixed
- Type of the route
- Reference to the route
- Number of axles on the track
Level crossing
- Selected status
- Actual status
- Indicator, if the level crossing secure system changes status
- Indicator, if a route over the element is selected
- Indicator, if a route over the element is fixed
- Type of the route
- Reference to the route
- Number of axles on the track
- Indicator, if a stop signal exists
Derailer
Track
- Trafficability loxk
- Indicator, if a trafficability lock is projected
- Explaination text for the lock
- Indicator, if a explaination text is set
- Indicator, if the track is free or occupied
- Indicator, if a route over the element is selected
- Indicator, if a route over the element is fixed
- Type of the route
- Reference to the route
- Number of axles on the track
- Indicator, if a hardware feedback exists
Signals
Currently, this concept is under construction. The actual concept
foresees two classes. One class operates the distant caution signals,
the other class operates all other types of signals.
Details will follow.
Routes
The route concept will follow.
