AbstractSignalMast

public AbstractSignalMast(String systemName)

Method Details

setAspect

public void setAspect(@Nonnull
 String aspect)

Description copied from interface: SignalMast

Set aspect to a valid name in the current signal system definition.

Specified by:

setAspect in interface SignalMast

Parameters:

aspect - the new aspect shown

getAspect

public String getAspect()

Description copied from interface: SignalMast

Get current aspect name. Changes to this property can be listened to using the property Aspect.

Specified by:

getAspect in interface SignalMast

Returns:

the current aspect or null if not set

getSpeed

public String getSpeed()

getState

public int getState()

The state is the index of the current aspect in the list of possible aspects.

Specified by:

getState in interface NamedBean

Returns:

the state

setState

public void setState(int i)

Description copied from interface: NamedBean

Provide generic access to internal state.

This generally shouldn't be used by Java code; use the class-specific form instead (e.g. setCommandedState in Turnout). This is provided to make scripts access easier to read.

Specified by:

setState in interface NamedBean

Parameters:

i - the state

getLit

public boolean getLit()

Default behavior for "lit" property is to track value and return it.

Specified by:

getLit in interface Signal

Specified by:

getLit in interface SignalMast

Returns:

true if lit; false if dark

getHeld

public boolean getHeld()

"Held" property is just tracked and notified.

Specified by:

getHeld in interface Signal

Specified by:

getHeld in interface SignalMast

Returns:

true if held; false otherwise

setLit

public void setLit(boolean newLit)

Set the lit property.

This acts on all the SignalHeads included in this SignalMast

Specified by:

setLit in interface Signal

Specified by:

setLit in interface SignalMast

Parameters:

newLit - the new value of lit

setHeld

public void setHeld(boolean newHeld)

Set the held property of the signal mast.

Note that this does not directly effect the output on the layout; the held property is a local variable which effects the aspect only via higher-level logic.

Specified by:

setHeld in interface Signal

Specified by:

setHeld in interface SignalMast

Parameters:

newHeld - the new value of the help property

isAtStop

public boolean isAtStop()

Description copied from interface: Signal

Determine whether this signal shows an aspect or appearance that forbid travel past it. This might be a red appearance, or a Stop aspect. Stop-and-Proceed or Restricting would return false here.

Specified by:

isAtStop in interface Signal

Returns:

true if the signal is showing a stop indication; false otherwise

isShowingRestricting

public boolean isShowingRestricting()

Description copied from interface: Signal

Determine whether this signal shows an aspect or appearance that allows travel past it only at restricted speed. This might be a flashing red appearance, or a Restricting aspect.

Specified by:

isShowingRestricting in interface Signal

Returns:

true if the signal is showing a restricting indication; false otherwise

isCleared

public boolean isCleared()

Description copied from interface: Signal

Determine whether this signal shows an aspect or appearance that allows travel past it, e.g. it's "been cleared". This might be a yellow or green appearance, or an Approach or Clear aspect.

Specified by:

isCleared in interface Signal

Returns:

true if the signal is showing a clear indication; false otherwise

setPermissiveSmlDisabled

public void setPermissiveSmlDisabled(boolean disabled)

Specified by:

setPermissiveSmlDisabled in interface SignalMast

isPermissiveSmlDisabled

public boolean isPermissiveSmlDisabled()

Determine if the permissive SML logic should be disabled. The default will be false which means that automatic permissive processing is allowed. Prototypical CTC designs frequently require an additional action, such as Call-On, to enable permissive aspects.

Specified by:

isPermissiveSmlDisabled in interface SignalMast

Returns:

true if permissive SML is disabled.

configureSignalSystemDefinition

protected void configureSignalSystemDefinition(String name)

configureAspectTable

protected void configureAspectTable(String signalSystemName,
 String aspectMapName)

Specified by:

getAppearanceMap in interface SignalMast

getValidAspects

@Nonnull

Specified by:

getValidAspects in interface SignalMast

Returns:

sorted list of valid aspects; may be empty

getMastType

public String getMastType()

Get the specific mast type for this mast. This is the type that appears in the SystemName and filename, i.e. "SL-3-high" for the AAR-1946/appearance-SL-3-high.xml definition.

Specified by:

getMastType in interface SignalMast

Returns:

mast type.

setMastType

Specified by:

setMastType in interface SignalMast

Parameters:

type - mast type.

getAllKnownAspects

Sets whether the Signal Mast is allowed or configured to show an unlit aspect, or if it is always lit.

Specified by:

setAllowUnLit in interface SignalMast
