All Implemented Interfaces:

XmlAdapter

public class AbstractSignalHeadManagerXml
extends AbstractNamedBeanManagerConfigXML

Provides the abstract base and store functionality for configuring SignalHeadManagers, working with AbstractSignalHeadManagers.

Typically, a subclass will just implement the load(Element turnouts) class, relying on implementation here to load the individual turnouts. Note that these are stored explicitly, so the resolution mechanism doesn't need to see *Xml classes for each specific SignalHead or AbstractSignalHead subclass at store time.

Based on AbstractTurnoutManagerConfigXML

public AbstractSignalHeadManagerXml()

Method Detail

store

public org.jdom2.Element store(java.lang.Object o)

Default implementation for storing the contents of a SignalHeadManager.

Unlike most other managers, the individual SignalHead objects are stored separately via the configuration system so they can have separate type information.

Parameters:

o - Object to store, of type SignalHeadManager

Returns:

Element containing the complete info

setStoreElementClass

public void setStoreElementClass(org.jdom2.Element turnouts)

Subclass provides implementation to create the correct top element, including the type information. Default implementation is to use the local class here.

Parameters:

turnouts - The top-level element being created

load

public boolean load(org.jdom2.Element shared,
                    org.jdom2.Element perNode)

Create a SignalHeadManager object of the correct class, then register and fill it.

Specified by:

load in interface XmlAdapter

Overrides:

load in class AbstractXmlAdapter

Parameters:

shared - Shared top level Element to unpack.

perNode - Per-node top level Element to unpack.

Returns:

true if successful

loadSignalHeads

public void loadSignalHeads(org.jdom2.Element shared,
                            org.jdom2.Element perNode)

Utility method to load the individual SignalHead objects. If there's no additional info needed for a specific signal head type, invoke this with the parent of the set of SignalHead elements.

Parameters:

shared - Element containing the SignalHead elements to load.

perNode - Element containing any per-node information associated with the shared Element.

replaceSignalHeadManager

protected void replaceSignalHeadManager()

Replace the current signal head manager, if there is one, with one newly created during a load operation. This is skipped if they are of the same absolute type.

loadOrder

public int loadOrder()

Description copied from class: AbstractXmlAdapter

Specified by:

loadOrder in interface XmlAdapter

Overrides:

loadOrder in class AbstractXmlAdapter
