Constructor Detail

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

isXmlnsUrisNotAvailable

public boolean isXmlnsUrisNotAvailable()

Returns, whether the parser resolves namespace-URIs.

Returns:

true, if the parser will *NOT* resolve namespaces, false otherwise.

setXmlnsUrisNotAvailable

public void setXmlnsUrisNotAvailable(boolean xmlnsUrisNotAvailable)

Sets a hint that the parser will not be able to return URIs for XML-Namespaces. You should not see this nowadays, as all the common JAXP-parser implementations seem to work fine with namespaces.

Parameters:

xmlnsUrisNotAvailable - a flag indicating that the XML parser has troubles resolving namespaces.

getEntityResolver

public org.xml.sax.EntityResolver getEntityResolver()

Returns the entity resolver used in this handler.

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.

getSelectedRootHandler

public XmlFactoryModule getSelectedRootHandler()
