static

Create an AdjListPropertyChunkInfoReader instance from graph info and property group.

Parameters

graph_info	The graph info.
src_label	The source vertex label.
edge_label	The edge label.
dst_label	The destination vertex label.
property_group	The property group of the edge property.
adj_list_type	The adj list type for the edge.

◆ Make() [3/3]

Result< std::shared_ptr< AdjListPropertyChunkInfoReader > > graphar::AdjListPropertyChunkInfoReader::Make	(	const std::shared_ptr< GraphInfo > &	graph_info,
		const std::string &	src_label,
		const std::string &	edge_label,

		const std::string &	property_name,
		AdjListType	adj_list_type
	)

static

Create an AdjListPropertyChunkInfoReader instance from graph info and property name.

Parameters

graph_info	The graph info.
src_label	The source vertex label.
edge_label	The edge label.
dst_label	The destination vertex label.
property_name	The name of one property in the property group you want to read.

Definition at line 494 of file chunk_info_reader.cc.

◆ next_chunk()

Status graphar::AdjListPropertyChunkInfoReader::next_chunk ( )

Sets chunk position indicator to next chunk.

if current chunk is the last chunk, will return Status::IndexError error.

Definition at line 444 of file chunk_info_reader.cc.

◆ seek()

Status graphar::AdjListPropertyChunkInfoReader::seek ( IdType offset )

Sets chunk position indicator for reader by edge index.

Parameters

offset edge index of the vertex chunk. Note: the offset is the edge index of the vertex chunk, not the edge index of the whole graph.

Definition at line 425 of file chunk_info_reader.cc.

◆ seek_dst()

Status graphar::AdjListPropertyChunkInfoReader::seek_dst ( IdType id )

Sets chunk position indicator for reader by destination vertex id.

Parameters

id	the destination vertex id.

Definition at line 393 of file chunk_info_reader.cc.

◆ seek_src()

Status graphar::AdjListPropertyChunkInfoReader::seek_src ( IdType id )

Sets chunk position indicator for reader by source vertex id.

Parameters

id	the source vertex id.
