Method Detail

getDeepCopy

public Base getDeepCopy(java.util.Map<java.lang.String,java.lang.String> systemNames,
                        java.util.Map<java.lang.String,java.lang.String> userNames)

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.

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

getCategory

public Category getCategory()

Get the category.

Specified by:

getCategory in interface Base

Overrides:

getCategory in class AbstractBase

Returns:

the category

setValue

public void setValue(java.lang.String value)

getValue

public java.lang.String getValue()

evaluate

public java.lang.String evaluate()

Evaluate this expression.

Returns:

the result of the evaluation

getChild

public FemaleSocket getChild(int index)
                      throws java.lang.IllegalArgumentException,
                             java.lang.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:

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

java.lang.UnsupportedOperationException

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

getShortDescription

public java.lang.String getShortDescription(java.util.Locale locale)

Description copied from interface: Base

Parameters:

locale - The locale to be used

Returns:

a short description

getLongDescription

public java.lang.String getLongDescription(java.util.Locale locale)

Description copied from interface: Base

Get a long description of this item.

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.

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:

registerListenersForThisClass in class AbstractBase

unregisterListenersForThisClass

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:

unregisterListenersForThisClass in class AbstractBase

disposeMe

public void disposeMe()

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

Overrides:

disposeMe in class AbstractBase
