ElementMappingRegistry
public ElementMappingRegistry(FopFactory factory)
- Main constructor. Adds all default element mapping as well as detects ElementMapping
through the Service discovery.
- Parameters:
factory
- the Fop Factory
addElementMapping
public void addElementMapping(java.lang.String mappingClassName)
throws java.lang.IllegalArgumentException
- Add the element mapping with the given class name.
- Parameters:
mappingClassName
- the class name representing the element mapping.- Throws:
java.lang.IllegalArgumentException
- if there was not such element mapping.
addElementMapping
public void addElementMapping(ElementMapping mapping)
- Add the element mapping.
- Parameters:
mapping
- the element mapping instance
findFOMaker
public ElementMapping.Maker findFOMaker(java.lang.String namespaceURI,
java.lang.String localName,
org.xml.sax.Locator locator)
throws FOPException
- Finds the Maker used to create node objects of a particular type
- Parameters:
namespaceURI
- URI for the namespace of the elementlocalName
- name of the Elementlocator
- the Locator instance for context information- Returns:
- the ElementMapping.Maker that can create an FO object for this element
- Throws:
FOPException
- if a Maker could not be found for a bound namespace.
getDOMImplementationForNamespace
public org.w3c.dom.DOMImplementation getDOMImplementationForNamespace(java.lang.String namespaceURI)
- Tries to determine the DOMImplementation that is used to handled a particular namespace.
The method may return null for namespaces that don't result in a DOM. It is mostly used
in namespaces occurring in foreign objects.
- Parameters:
namespaceURI
- the namespace URI- Returns:
- the handling DOMImplementation, or null if not applicable
