This element hierarchy is similar to XrlAtom's but exclusive to policy components.

Member Function Documentation

virtual string Element::str ( ) const [pure virtual]

Every element must be representable by a string.

This is a requirement to enable the policy manager to send elements to the backend filters via XRL calls for example.

Returns:
string representation of the element.

Implemented in ElemFilter, ElemNull, ElemSetAny< T >, ElemInt32, ElemU32, ElemCom32, ElemStr, ElemBool, ElemAny< T >, ElemRefAny< T >, ElemNet< A >, and ElemNextHop< A >.

virtual const char* Element::type ( ) const [pure virtual]
Returns:
string representation of element type.

Implemented in ElemFilter, ElemNull, ElemSetAny< T >, ElemInt32, ElemU32, ElemCom32, ElemStr, ElemBool, ElemAny< T >, ElemRefAny< T >, ElemNet< A >, and ElemNextHop< A >.
