Method Details

getDeepCopy

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

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:

JmriException - in case of an error

getExpressionSystemName

public String getExpressionSystemName(int index)

getExpressionManager

public String getExpressionManager(int index)

setFormula

public final void setFormula(String formula)
                      throws ParserException

Throws:

ParserException

getFormula

public String getFormula()

the category

evaluate

public double evaluate()
                throws JmriException

Evaluate this expression.

Specified by:

evaluate in interface AnalogExpression

Returns:

the result of the evaluation. The male socket that holds this expression throws an exception if this value is a Double.NaN or an infinite number.

Throws:

JmriException - when an exception occurs

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()

UnsupportedOperationException - when needed

getChildCount

public int getChildCount()

Description copied from class: AbstractBase

Get the number of children.

Specified by:

getChildCount in interface Base

Overrides:

getChildCount in class AbstractBase

Returns:

the number of children

setChildCount

Returns:

a short description

getLongDescription

public String getLongDescription(Locale locale)

Description copied from interface: Base

Get a long description of this item.

Specified by:
