Class XMLDataObject

java.lang.Object
  extended byorg.openide.loaders.DataObject
      extended byorg.openide.loaders.MultiDataObject
          extended byorg.openide.loaders.XMLDataObject
All Implemented Interfaces:
HelpCtx.Provider, Node.Cookie, Serializable
public class XMLDataObject
extends MultiDataObject

Object that provides main functionality for xml documents. These objects are recognized by the xml extension and text/xml MIME type.

It is declaratively extensible by an Environment. The Environment is assigned to document instances using a provider registered by DOCTYPE's public ID in the system filesystem under xml/lookups/{Transformed-DOCTYPE} where the DOCTYPE transformation is the same as that defined for EntityCatalog registrations.

XMLUtil, EntityCatalog, Serialized Form

Constructor Summary
XMLDataObject(FileObject fo, MultiFileLoader loader)
          Create new XMLDataObject.
 
Method Summary
static boolean addEntityResolver(EntityResolver resolver)
          Deprecated. EntityResolver is a parser user responsibility. Every time set a EntityResolver to an XML parser you use. The OpenIDE now defines a system EntityCatalog.
static Document createDocument()
          Deprecated. Replaced with XMLUtil It directly violates DOM's root element reference read-only status. If you can not move to XMLUtil for compatabilty reasons please replace with following workaround: 
 String templ = "";
 InputSource in = new InputSource(new StringReader(templ));
 in.setSystemId("StringReader");  //workaround
 DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
 Document doc = builder.parse(in);
protected  EditorCookie createEditorCookie()
          Deprecated. CookieSet factory should be used by subclasses instead.
static InputSource createInputSource(URL url)
          Deprecated. Deprecated as it was a workaround method. Replace with new InputSource(url.toExternalForm()).
protected  Node createNodeDelegate()
          If the Info associated with this data object (if any) provides a subclass of Node, then this object is created to represent the XML data object, otherwise DataNode is created.
static Parser createParser()
          Deprecated. Use XMLUtil instead. It will create a SAX XMLReader that is SAX Parser replacement. You will have to replace DocumentHandler by ContentHandler besause XMLReader accepts just ContentHandler.

Alternatively if not interested in new callbacks defined by SAX 2.0 you can wrap returned XMLReader into XMLReaderAdapter that implements Parser.
static Parser createParser(boolean validate)
          Deprecated. Use Util instead setting ns to false. For more details see createParser
 Node.Cookie getCookie(Class cls)
          Cookies from assigned Environment are not placed into protected CookieSet and can be obtained only by invoking this method.
 Document getDocument()
          Creates w3c's document for the xml file.
 HelpCtx getHelpCtx()
          Get help context for this object.
 XMLDataObject.Info getInfo()
          Deprecated. not used anymore
static XMLDataObject.Info getRegisteredInfo(String publicId)
          Deprecated. Register via lookup
 int getStatus()
           
protected  void handleDelete()
          Delete this object (implemented by subclasses).
static Document parse(URL url)
          Deprecated. Use XMLUtil instead setting null error handler and validation to false.
static Document parse(URL url, boolean validate)
          Deprecated. Use XMLUtil instead setting null handler.
static Document parse(URL url, ErrorHandler eh)
          Deprecated. Use XMLUtil instead setting validation to false.
static Document parse(URL url, ErrorHandler eh, boolean validate)
          Deprecated. Use XMLUtil instead.
static void registerCatalogEntry(String publicId, String uri)
          Deprecated. Do not rely on global (non-modular) resolvers. Use EntityCatalog and XMLUtil instead.
static void registerCatalogEntry(String publicId, String resourceName, ClassLoader loader)
          Deprecated. Do not rely on global (non-modular) resolvers. Use EntityCatalog and XMLUtil instead.
static void registerInfo(String publicId, XMLDataObject.Info info)
          Deprecated. Register an Environment via lookup, see some details.
static EntityResolver removeEntityResolver(EntityResolver resolver)
          Deprecated. EntityResolver is a parser user responsibility.

Deprecated. Do not rely on global (non-modular) resolvers. Use EntityCatalog and XMLUtil instead.

Registers the given public ID as corresponding to a particular URI, typically a local copy. This URI will be used in preference to ones provided as system IDs in XML entity declarations. This mechanism would most typically be used for Document Type Definitions (DTDs), where the public IDs are formally managed and versioned.

Any created parser use global entity resolver and you can register its catalog entry.

Parameters:
publicId - The managed public ID being mapped
uri - The URI of the preferred copy of that entity

registerCatalogEntry

Deprecated. Do not rely on global (non-modular) resolvers. Use EntityCatalog and XMLUtil instead.

Registers a given public ID as corresponding to a particular Java resource in a given class loader, typically distributed with a software package. This resource will be preferred over system IDs included in XML documents. This mechanism should most typically be used for Document Type Definitions (DTDs), where the public IDs are formally managed and versioned.

If a mapping to a URI has been provided, that mapping takes precedence over this one.

Any created parser use global entity resolver and you can register its catalog entry.

Parameters:
publicId - The managed public ID being mapped
resourceName - The name of the Java resource
loader - The class loader holding the resource, or null if it is a system resource.

addEntityResolver

public static final boolean addEntityResolver(EntityResolver resolver)
Deprecated. EntityResolver is a parser user responsibility. Every time set a EntityResolver to an XML parser you use. The OpenIDE now defines a system EntityCatalog.

Every created parser use global entity resolver and then chain.

Parameters:
resolver - non null resolver to be added
Returns:
true if successfully added

removeEntityResolver

public static final EntityResolver removeEntityResolver(EntityResolver resolver)
Deprecated. EntityResolver is a parser user responsibility.

Remove a given entity resolver from IDE resolver chain.

Every created parser use global entity resolver and then chain.

Parameters:
resolver - non null resolver to be removed
Returns:
removed resolver instance or null if not present

registerInfo

public static void registerInfo(String publicId,

Registers new Info to particular XML document content type as recognized by DTD public id. The registration is valid until IDE JVM termination.

Parameters:
publicId - used as key
info - associated value or null to unregister

getRegisteredInfo

public static XMLDataObject.Info getRegisteredInfo(String publicId)
