public class DocumentFactory

extends Object

implements Serializable

DocumentFactory is a collection of factory methods to allow easy custom building of DOM4J trees. The default tree that is built uses a doubly linked tree.

The tree built allows full XPath expressions from anywhere on the tree.

Returns:

a new XPath instance

Throws:

InvalidXPathException - if the XPath expression is invalid

createXPath

public XPath createXPath(String xpathExpression,
                         org.jaxen.VariableContext variableContext)

variableContext - is the variable context to use when evaluating the XPath

Returns:

a new XPath instance

Parameters:

xpathFilterExpression - is the XPath filter expression to create

variableContext - is the variable context to use when evaluating the XPath

Returns:

a new NodeFilter instance

createXPathFilter

public NodeFilter createXPathFilter(String xpathFilterExpression)

createXPathFilter parses a NodeFilter from the given XPath filter expression. XPath filter expressions occur within XPath expressions such as self::node()[ filterExpression ]

Returns:

a new NodeFilter instance

createPattern

public List getQNames()

Returns a list of all the QName instances currently used by this document factory

Returns:

DOCUMENT ME!

getXPathNamespaceURIs

public Map getXPathNamespaceURIs()

DOCUMENT ME!

Returns:

the Map of namespace URIs that will be used by by XPath expressions to resolve namespace prefixes into namespace URIs. The map is keyed by namespace prefix and the value is the namespace URI. This value could well be null to indicate no namespace URIs are being mapped.

setXPathNamespaceURIs

public void setXPathNamespaceURIs(Map namespaceURIs)

Sets the namespace URIs to be used by XPath expressions created by this factory or by nodes associated with this factory. The keys are namespace prefixes and the values are namespace URIs.

Parameters:

namespaceURIs - DOCUMENT ME!

createSingleton

protected static DocumentFactory createSingleton(String className)

createSingleton creates the singleton instance from the given class name.

Parameters:

className - is the name of the DocumentFactory class to use

Returns:

a new singleton instance.

intern

protected QName intern(QName qname)

DOCUMENT ME!

Parameters:

qname - DOCUMENT ME!

Returns:

the cached QName instance if there is one or adds the given qname to the cache if not

createQNameCache

protected QNameCache createQNameCache()

Factory method to create the QNameCache. This method should be overloaded if you wish to use your own derivation of QName.

Returns:

DOCUMENT ME!

init

protected void init()
