Method Details

getDeepCopy

public Base getDeepCopy(Map<String,String> systemNames,
 Map<String,String> userNames)
                 throws ParserException

Description copied from interface: Base

Create a deep copy of myself and my children The item needs to try to lookup itself in both systemNames and userNames to see if the user has given a new system name and/or a new user name.If no new system name is given, an auto system name is used. If no user name is given, a null user name is used.

Specified by:

getDeepCopy in interface Base

Parameters:

systemNames - a map of old and new system name

userNames - a map of old system name and new user name

Returns:

a deep copy

Throws:

ParserException

set_Is_IsNot

public void set_Is_IsNot(Is_IsNot_Enum is_IsNot)

get_Is_IsNot

public Is_IsNot_Enum get_Is_IsNot()

setBeanState

public void setBeanState(ExpressionPower.PowerState state)

getBeanState

public ExpressionPower.PowerState getBeanState()

setIgnoreUnknownState

public void setIgnoreUnknownState(boolean ignoreUnknownState)

isIgnoreUnknownState

public boolean isIgnoreUnknownState()

getCategory

public LogixNG_Category getCategory()

Get the category.

Specified by:

getCategory in interface Base

Overrides:

getCategory in class AbstractBase

Returns:

the category

evaluate

public boolean evaluate()
                 throws JmriException

Evaluate this expression.

Specified by:

evaluate in interface DigitalExpression

Returns:

the result of the evaluation

Throws:

JmriException - when an exception occurs

getChild

public FemaleSocket getChild(int index)
                      throws IllegalArgumentException,
UnsupportedOperationException

Description copied from class: AbstractBase

Get a child of this item

Specified by:

getChild in interface Base

Overrides:

getChild in class AbstractBase

Parameters:

index - the index of the child to get

Returns:

the child

Throws:

IllegalArgumentException - if the index is less than 0 or greater or equal with the value returned by getChildCount()

public String getLongDescription(Locale locale)

Description copied from interface: Base

Get a long description of this item.

Specified by:

getLongDescription in interface Base

Parameters:

locale - The locale to be used

Returns:

a long description

setup

public void setup()

Setup this object and its children. This method is used to lookup system names for child sockets, turnouts, sensors, and so on.

Specified by:

setup in interface Base

registerListenersForThisClass

public void registerListenersForThisClass()

Register listeners if this object needs that.

Important: This method may be called more than once. Methods overriding this method must ensure that listeners are not registered more than once.

Overrides:

public void unregisterListenersForThisClass()

Unregister listeners if this object needs that.

Important: This method may be called more than once. Methods overriding this method must ensure that listeners are not unregistered more than once.

Overrides:

propertyChange

public void propertyChange(PropertyChangeEvent evt)

Specified by:

propertyChange in interface PropertyChangeListener

disposeMe

public void disposeMe()

Dispose this class. Listeners do not need to be unregistered by this method since they are unregistered by dispose().

Overrides:
