Class TurnoutOperationManager

java.lang.Object

jmri.TurnoutOperationManager

All Implemented Interfaces:

InstanceManagerAutoDefault

public class TurnoutOperationManager
extends Object
implements InstanceManagerAutoDefault

class to look after the collection of TurnoutOperation subclasses Unlike the other xxxManager, this does not inherit from AbstractManager since the resources it deals with are not DCC system resources but rather purely internal state.

Constructor Details

TurnoutOperationManager

public TurnoutOperationManager()

Method Details

dispose

public void dispose()

getTurnoutOperations

public TurnoutOperation[] getTurnoutOperations()

addOperation

protected void addOperation(@Nonnull
 TurnoutOperation op)

add a new operation Silently replaces any existing operation with the same name

Parameters:

op - TurnoutOperation to add/replace

removeOperation

protected void removeOperation(@Nonnull
 TurnoutOperation op)

getOperation

public TurnoutOperation getOperation(@Nonnull
 String name)

Find a TurnoutOperation by its name.

Parameters:

name - name of TurnoutOperation to retrieve.

Returns:

the operation

loadOperationTypes

public void loadOperationTypes()

Load the operation types given by the current TurnoutManager instance, in the order given.

The order is important because the acceptable feedback modes may overlap. All we do is instantiate the classes. The constructors take care of putting everything in the right places. We allow multiple occurrences of the same name without complaining so the Proxy stuff works. There's a threading problem here, because this invokes gets the current turnout manager, often the proxy manager, which in turn invokes loadOperationTypes again. This is bad. It's not clear why it even works.

getMatchingOperationAlways

public TurnoutOperation getMatchingOperationAlways(@Nonnull
 Turnout t,
 int apparentMode)

Find a suitable operation for this turnout, based on its feedback type. The mode is passed separately so the caller can transform it

Parameters:

t - turnout

apparentMode - Turnout Feedback mode(s) to be used when finding a matching operation

Returns:

the turnout operation

getMatchingOperation

public TurnoutOperation getMatchingOperation(@Nonnull
 Turnout t,
 int apparentMode)

Find the correct operation for this turnout. If operations are globally disabled, return null.

Parameters:

t - turnout

apparentMode - mode(s) to be used when finding a matching operation

Returns:

operation

getMatchingOperationAlways

public TurnoutOperation getMatchingOperationAlways(@Nonnull
 Turnout t)

getDoOperations

public boolean getDoOperations()

Get ( potentially update ) status of whether operations are in use.

Returns:

true if in use, else false.

setDoOperations

public void setDoOperations(boolean b)

Set that Turnout Operations are in use.

Parameters:

b - true to use, else false to disable.

concatenateTypeLists

public static String[] concatenateTypeLists(@Nonnull
 String[] types)

Proxy support. Take a concatenation of operation type lists from multiple systems and turn it into a single list, by eliminating duplicates and ensuring that NoFeedback - which matches anything - comes at the end if it is present at all.

Parameters:

types - list of types possibly containing duplicates

Returns:

list reduced as described above

addPropertyChangeListener

public void addPropertyChangeListener(@Nonnull
 PropertyChangeListener l)

removePropertyChangeListener

public void removePropertyChangeListener(@Nonnull
 PropertyChangeListener l)

firePropertyChange

protected void firePropertyChange(@Nonnull
 String p,
 Object old,
 Object n)

getTooltipForOperator

public String getTooltipForOperator(String operatorName,
 Turnout t)

Get a ToolTip or descriptive comment for the Operator.

Parameters:

operatorName - name of the Turnout Operator

t - The Turnout that the Operator would operate

Returns:

Descriptive String, or null.
