jmri.configurexml
Class AbstractMemoryManagerConfigXML

java.lang.Object
  jmri.configurexml.AbstractMemoryManagerConfigXML

All Implemented Interfaces:

XmlAdapter

Direct Known Subclasses:

BlockManagerXml, DefaultMemoryManagerXml

public abstract class AbstractMemoryManagerConfigXML
extends Object
implements XmlAdapter

Provides the abstract base and store functionality for configuring MemoryManagers, working with AbstractMemoryManagers.

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

AbstractMemoryManagerConfigXML

public AbstractMemoryManagerConfigXML()

Method Detail

store

public org.jdom.Element store(Object o)

Default implementation for storing the contents of a MemoryManager

Specified by:

store in interface XmlAdapter

Parameters:

o - Object to store, of type MemoryManager

Returns:

Element containing the complete info

setStoreElementClass

public abstract void setStoreElementClass(org.jdom.Element memories)

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

Parameters:

memories - The top-level element being created

load

public void load(org.jdom.Element element,
                 Object o)

Description copied from interface: XmlAdapter

Create a set of configured objects from their XML description, using an auxiliary object.

For example, the auxilary object o might be a manager or GUI of some type that needs to be informed as each object is created.

Specified by:

load in interface XmlAdapter

Parameters:

element - Top-level XML element containing the description

o - Implementation-specific Object needed for the conversion

load

public abstract void load(org.jdom.Element memories)

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

Specified by:

load in interface XmlAdapter

Parameters:

memories - Top level Element to unpack.

loadMemories

public void loadMemories(org.jdom.Element memories)

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

Parameters:

memories - Element containing the Memory elements to load.
