MultiplexRootElementHandler

public MultiplexRootElementHandler(org.pentaho.reporting.libraries.resourceloader.ResourceManager manager,
                                   org.pentaho.reporting.libraries.resourceloader.ResourceKey source,
                                   org.pentaho.reporting.libraries.resourceloader.ResourceKey context,
                                   long version,
                                   XmlFactoryModule[] rootHandlers)

Creates a new MultiplexRootElementHandler for the given root handler selection.

Parameters:

manager - the resource manager that loaded this xml-file.

source - the source-key that idenfies from where the file was loaded.

context - the key that should be used to resolve relative paths.

version - the versioning information for the root-file.

rootHandlers - the roothandlers, never null.

Method Detail

getEntityResolver

public EntityResolver getEntityResolver()

Returns the entity resolver used in this handler.

Overrides:

getEntityResolver in class RootXmlReadHandler

Returns:

the entity resolver.

getParserEntityResolver

public ParserEntityResolver getParserEntityResolver()

Returns the parent entity resolver used in the element handler. This returns the modifiable entity-resolver backend.

Returns:

the entity resolver.

getRootHandlers

protected XmlFactoryModule[] getRootHandlers()

Returns all known roothandlers.

Returns:

the known root handlers.

interceptFirstStartElement

protected void interceptFirstStartElement(String originalUri,
                                          String localName,
                                          String qName,
                                          Attributes attributes)
                                   throws SAXException

Starts processing an element.

Overrides:

interceptFirstStartElement in class RootXmlReadHandler

Parameters:

originalUri - the URI.

localName - the local name.

qName - the qName.

attributes - the attributes.

Throws:

SAXException - if there is a parsing problem.

getSelectedRootHandler

public XmlFactoryModule getSelectedRootHandler()
