Detailed Description

HistoryComponent class describes the component information (name, type) stored in the history.

In CamiTK, every Action are stored in a history, which can be saved as a XML file.
Each history entry is an instance of HistoryItem and provides information about the processed action :

the name of the action processed.
the properties (name, values).
its input components, stored as HistoryComponent instances.
its output components, stored as HistoryComponent instances.

History items are mainly useful for getting back to a previous state by undoing an action or for scripting by storing in a file a pipeline of actions written in Python.
The history is stored in the Application class and uses the "construct on first use" idiom/design-pattern (with singletons).
It therefore avoids the infamous "static initialization order fiasco", see http://www.parashift.com/c++-faq/ctors.html

Member Enumeration Documentation

◆ Type

enum camitk::HistoryComponent::Type

The different Type (of representation) of the associated Component.

Use getType() to get the information about a specific HistoryComponent.

Note

The type is highly linked to Component::Representation information :

ImageComponent instances have subcomponents of representation SLICE.
MeshComponent instances have a representation of type GEOMETRY.
Other components have no representation (NO_REPRESENTATION), and are thus of type OTHER.

As for Component::Representation the HistoryComponent type cannot be NULL : if a Component has no representation, then he is of type OTHER

Enumerator
IMAGE_COMPONENT	this Component represents a volumic image and its subcomponents can be displayed as slices.
MESH_COMPONENT	this Component represent a 3D mesh, it has a 3D representation which can be displayed in the 3D viewer.
OTHER	this Component has no defined representation.
