Detailed Description

HistoryItem class describes the entry of an action used in a pipeline, 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
