Field Detail

PROP_CHECK_PRIOR_LISTS_EMPTY

@S4Boolean(defaultValue=false)
public static final java.lang.String PROP_CHECK_PRIOR_LISTS_EMPTY

This property is used in the Iterator returned by the getNonEmittingListIterator() method. When the Iterator.next() method is called, this property determines whether the lists prior to that returned by next() are empty (they should be empty). If they are not empty, an Error will be thrown.

newProperties

public void newProperties(PropertySheet ps)
                   throws PropertyException

Description copied from interface: Configurable

This method is called when this configurable component needs to be reconfigured.

Specified by:

newProperties in interface Configurable

Parameters:

ps - a property sheet holding the new data

Throws:

PropertyException - if there is a problem with the properties.

setNumStateOrder

public void setNumStateOrder(int numStateOrder)

Description copied from interface: ActiveListManager

Sets the total number of state types to be managed

Specified by:

setNumStateOrder in interface ActiveListManager

Parameters:

numStateOrder - the total number of state types

add

public void add(Token token)

Adds the given token to the list

Specified by:

add in interface ActiveListManager

Parameters:

token - the token to add

replace

public void replace(Token oldToken,
                    Token newToken)

Replaces an old token with a new token

Specified by:

replace in interface ActiveListManager

Parameters:

oldToken - the token to replace (or null in which case, replace works like add).

newToken - the new token to be placed in the list.

getEmittingList

public ActiveList getEmittingList()

Returns the emitting ActiveList, and removes it from this manager.

Specified by:

getEmittingList in interface ActiveListManager

Returns:

the emitting ActiveList

getNonEmittingListIterator

public java.util.Iterator getNonEmittingListIterator()

Returns an Iterator of all the non-emitting ActiveLists. The iteration order is the same as the search state order.

Specified by:

getNonEmittingListIterator in interface ActiveListManager

Returns:

an Iterator of non-emitting ActiveLists

dump

public void dump()

Outputs debugging info for this list manager

Specified by:

dump in interface ActiveListManager
