• topUri and backUri - uris to previous bean and top - root bean.
• current - reference to the object referenced with the path
• propertiesError - if error occured setting properties
• beans - list of BeanDef objects - if object is of ConfigurableApplicationContext type.
• map - list of BeanDef objects - if object is of Map type.
• collection - list of BeanDef objects - if object is of Collection type.
• properties - list of BeanDef objects - object accessible properties.
• methods - list of MethodDescriptor object - methods that are not used for properties' access.
