Constructor & Destructor Documentation

◆ VertexIter() [1/2]

graphar::VertexIter::VertexIter ( const std::shared_ptr< VertexInfo > &  vertex_info,
const std::string &  prefix,
IdType  offset 
)
inlineexplicitnoexcept

Initialize the iterator.

Parameters
vertex_infoThe vertex info that describes the vertex type.
prefixThe absolute prefix.
offsetThe current offset of the readers.

Definition at line 174 of file graph_reader.h.

◆ VertexIter() [2/2]

graphar::VertexIter::VertexIter ( const VertexIter &  other)
inline

Copy constructor.
