Field Summary final static  long serialVersionUID      Constructor Summary public   XNull()      Create an XObject. Method Summary public  boolean bool()      Cast result object to a boolean. public  boolean equals(XObject obj2)      Tell if two objects are functionally equal. public  int getType()      Tell what kind of class this is. public  String getTypeString()      Given a request type, return the equivalent string. public  double num()      Cast result object to a number. public  int rtf(XPathContext support)      Cast result object to a result tree fragment. public  String str()      Cast result object to a string. Field Detail serialVersionUID final static long serialVersionUID(Code) Constructor Detail XNull public XNull()(Code) Create an XObject. Method Detail bool public boolean bool()(Code) Cast result object to a boolean. false equals public boolean equals(XObject obj2)(Code) Tell if two objects are functionally equal. Parameters:   obj2 - Object to compare this to True if the given object is of type CLASS_NULL getType public int getType()(Code) Tell what kind of class this is. type CLASS_NULL getTypeString public String getTypeString()(Code) Given a request type, return the equivalent string. For diagnostic purposes. type string "#CLASS_NULL" num public double num()(Code) Cast result object to a number. 0.0 rtf public int rtf(XPathContext support)(Code) Cast result object to a result tree fragment.
