Detailed Description

template<typename OID_T, typename VDATA_T, typename EDATA_T>
class grape::FragmentBase< OID_T, VDATA_T, EDATA_T >

FragmentBase is the base class for fragments.

Note

: The pure virtual functions in the class work as interfaces, instructing sub-classes to implement. The override functions in the derived classes would be invoked directly, not via virtual functions.

Template Parameters

OID_T
VDATA_T
EDATA_T

Member Function Documentation
