All Known Implementing Classes:

DefaultSignalSystem

public interface SignalSystem
extends NamedBean

A SignalSystem defines a signalling system by representing the properties of various signal aspects it contains.

At present, the signal aspects are enumerated by Strings, not by specific objects; this table exists to attach properties to those Strings.

Setting or getting the "state" of one of these will throw an error.

You'll have one of these objects for each signaling _system_ on your railroad. In turn, these will be used by 1 to N specific mappings to appearances, see e.g. SignalAppearanceMap.

Insertion order is preserved when retrieving keys.

Method Detail

setProperty

void setProperty(java.lang.String aspect,
                 java.lang.String key,
                 java.lang.Object value)

getProperty

java.lang.Object getProperty(java.lang.String aspect,
                             java.lang.String key)

setImageType

void setImageType(java.lang.String type)

Add an image or icon type available for use with this signaling system.

Parameters:

type - the image type

getImageTypeList

java.util.Enumeration<java.lang.String> getImageTypeList()

Returns a list of the image/icon sets available for use with this signaling system.

Returns:

all image types or an empty list

getAspects

java.util.Enumeration<java.lang.String> getAspects()

Get all aspects currently defined.

Returns:

all aspects or an empty list

getKeys

java.util.Enumeration<java.lang.String> getKeys()

Get all keys currently defined on any aspect.

Each key only appears once, even if used on more than one aspect.

Note that a given key may or may not appear on a given aspect.

Returns:

all keys or an empty list

checkAspect

boolean checkAspect(java.lang.String aspect)

Is this aspect known?

Parameters:

aspect - the aspect to check

Returns:

true if known; false otherwise

getAspect

java.lang.String getAspect(java.lang.Object obj,
                           java.lang.String key)

getMaximumLineSpeed

float getMaximumLineSpeed()

summary

java.lang.String summary()

Provide a multi-line summary of the signal system content, typically for printing.

Not intended for further parsing, i.e. for persistance, as format likely to differ from type to type, and to change often.

Returns:

summary string.
