helios.layouts.base.NetworkLayoutIPCServerCalc

class helios.layouts.base.NetworkLayoutIPCServerCalc(num_nodes, num_edges, edges_buffer_name, positions_buffer_name, info_buffer_name, weights_buffer_name=None, dimension=3, snaphosts_buffer_name=None, num_snapshots=0)

Bases: abc.ABC

An abstract class which reads the network information from the shared memory resources.

This should be used inside of a subprocess which will update the network layout positions

Parameters

• num_nodes (int) –

• num_edges (int) –

• edges_buffer_name (str) –

• positions_buffer_name (str) –

• info_buffer_name (str) –

• weights_buffer_name (str, optional) –

• dimension (int) –

• snaphosts_buffer_name (str, optional) –

• num_snapshots (int, optional) –

Methods

start

This method starts the network layout algorithm.

abstract start(steps=100, iters_by_step=3)

This method starts the network layout algorithm.

Parameters

• steps (int) – number of iterations to perform

• iters_by_step (int) – number of iterations to perform between each step
