BeanPointer

public BeanPointer(QName name,
                   Object bean,
                   JXPathBeanInfo beanInfo,
                   Locale locale)

BeanPointer

public BeanPointer(NodePointer parent,
                   QName name,
                   Object bean,
                   JXPathBeanInfo beanInfo)
Parameters:
name - is the name given to the first node

Method Details

asPath

public String asPath()
