Detailed Description

Typedef Documentation

sgraph_edge_data

typedef std::vector<flexible_type> turi::sgraph_edge_data

The type of data that can be stored on edges

Definition at line 27 of file sgraph_types.hpp.

sgraph_vertex_data

typedef std::vector<flexible_type> turi::sgraph_vertex_data

The type of data that can be stored on vertices

Definition at line 22 of file sgraph_types.hpp.

Function Documentation

add_vertex_field()

template<typename T , typename FLEX_TYPE >

bool turi::sgraph::add_vertex_field	(	std::vector< std::vector< T >> &	column,
		std::string	column_name,
		flex_type_enum	column_type,
		size_t	group = 0
	)

Same as add_vertex_field, but all values are in memory The column must exist. Assertion failure otherwise.

Definition at line 838 of file sgraph.hpp.

replace_vertex_field()

template<typename T , typename FLEX_TYPE >

bool turi::sgraph::replace_vertex_field	(	std::vector< std::vector< T >> &	column,
		std::string	column_name,
		size_t	group = 0
	)

Same as replace_vertex_field, but all values are in memory The column must exist. Assertion failure otherwise.

Definition at line 866 of file sgraph.hpp.

save_sgraph_to_csv()

void turi::save_sgraph_to_csv	(	const sgraph &	g,
		std::string	targetdir
	)

Write the content of the graph into a collection csv files under target directory. The vertex data are saved to vertex-groupid-partitionid.csv and edge data are saved to edge-groupid-partitionid.csv.

save_sgraph_to_json()

void turi::save_sgraph_to_json	(	const sgraph &	g,
		std::string	targetfile
	)

Write the content of the graph into a json file.
