robokudo.vis.visualizer¶

Classes¶

Visualizer

Module Contents¶

class robokudo.vis.visualizer.Visualizer(pipeline: robokudo.pipeline.Pipeline, shared_visualizer_state=None)¶

Bases: object

class Observable¶

_observers = []¶

register_observer(observer)¶

notify_observers(*args, **kwargs)¶

class Observer¶

notify(observable, *args, **kwargs)¶

class SharedState¶

Bases: Observable

A SharedState for single-view annotators. They can switch between all Annotators to visualize a single ‘active’ Annotator.

An Observer pattern is used to notify Visualizers that the to-be-shown content has to be updated due to processed inputs. It is NOT used for new data.

active_annotator = None¶

active_annotator_i = 0¶

instances = []¶

pipeline¶

indicate_termination_var = False¶

shared_visualizer_state = None¶

update_output = True¶

new_data = False¶

rk_logger = None¶

pre_tick()¶

tick()¶: The main method of each Visualizer. It is responsible for creating the necessary outputs that the Visualizer should show.

post_tick()¶

static static_post_tick()¶: This method is intended to be only called once per Visualizer Type, independent of the amount of same-typed Visualizers

classmethod new_visualizer_instance(pipeline: robokudo.pipeline.Pipeline, shared_visualizer_state=None)¶

static clear_visualizer_instances()¶

insert_input()¶

activate_update_output()¶

new_data_available()¶: The caller tells this Visualizer, that new data is available for retrieval.

indicate_termination()¶: This indicates the caller if this Visualizer thinks the program execution should be terminated.

static get_unique_types_of_visualizer_instances()¶

update_output_flag_for_new_data() → None¶: If this Visualizer gets new data, set the update flag for rendering purposes accordingly.
