Method Detail

parseOJElement

public static OJElement parseOJElement(String expr)
                                throws IllegalArgumentException

A utility method that uses only default settings to parse a string.

Parameters:

expr -

Returns:

the parsed OJElement detached from any parent.

Throws:

IllegalArgumentException

convertTreeToOJ

public static OJElement convertTreeToOJ(Element elt)

Takes a subtree of JDOM elements and converts it to a subtree of OJElements including subclasses according to OJFactory. If this object or any child is an OJElement, it is unchanged thus keeping extra information such as set by

Parameters:

elt - the element to be converted which will be taken apart by the process. Please clone before if this object still needs to work.

Returns:

the replaced element (is the same iff elt is an OJElement.

setSAXDriverClass

public void setSAXDriverClass(Class saxDriverClass)

Overrides any setting for a sax-driver class by explicitly providing the class. This allows delicate class-loader environments to pre-load the class for us thereby avoiding a call to Class.forName(java.lang.String).

createParser

protected XMLReader createParser()
                          throws JDOMException

Overrides:

createParser in class SAXBuilder

Throws:

JDOMException

createContentHandler

protected SAXHandler createContentHandler()

Overrides:

createContentHandler in class SAXBuilder

getFactory

public JDOMFactory getFactory()

Overrides:

getFactory in class SAXBuilder

setFactory

public void setFactory(JDOMFactory factory)

Overriden just to ensure the factory is of type OJFactory.

Overrides:

setFactory in class SAXBuilder

Throws:

IllegalArgumentException - if this is not the case.
