EdgeFrame __init__

---

__init__(self, graph=None, label=None, src_vertex_label=None, dest_vertex_label=None, directed=None)

Examples

Parameters:

graph : (default=None)

label : (default=None)

src_vertex_label : (default=None)

dest_vertex_label : (default=None)

directed : (default=None)

Given a data file /movie.csv, create a frame to match this data and move the data to the frame. Create an empty graph and define some vertex and edge types.

>>> my_csv = ta.CsvFile("/movie.csv", schema= [('user_id', int32),
...                                     ('user_name', str),
...                                     ('movie_id', int32),
...                                     ('movie_title', str),
...                                     ('rating', str)])

>>> my_frame = ta.Frame(my_csv)
>>> my_graph = ta.Graph()
>>> my_graph.define_vertex_type('users')
>>> my_graph.define_vertex_type('movies')
>>> my_graph.define_edge_type('ratings','users','movies',directed=True)

Add data to the graph from the frame:

>>> my_graph.vertices['users'].add_vertices(my_frame, 'user_id', ['user_name'])
>>> my_graph.vertices['movies].add_vertices(my_frame, 'movie_id', ['movie_title])

Create an edge frame from the graph, and add edge data from the frame.

>>> my_edge_frame = graph.edges['ratings']
>>> my_edge_frame.add_edges(my_frame, 'user_id', 'movie_id', ['rating']

Retrieve a previously defined graph and retrieve an EdgeFrame from it:

>>> my_old_graph = ta.get_graph("your_graph")
>>> my_new_edge_frame = my_old_graph.edges["your_label"]

Calling methods on an EdgeFrame:

>>> my_new_edge_frame.inspect(20)

Copy an EdgeFrame to a frame using the copy method:

>>> my_new_frame = my_new_edge_frame.copy()
