class PrefixActions#

A container for groups of actions carried out during an UnlinkLinkTransaction.

Parameters:

remove_menu_action_groups -- Actions which remove menu items
unlink_action_groups -- Actions which unlink files
unregister_action_groups -- Actions which unregister environment locations
link_action_groups -- Actions which link files
register_action_groups -- Actions which register environment locations
compile_action_groups -- Actions which compile pyc files
make_menu_action_groups -- Actions which create menu items
entry_point_action_groups -- Actions which create python entry points
prefix_record_groups -- Actions which create package json files in conda-meta/
initial_action_groups -- User-defined actions which run before all other actions
final_action_groups -- User-defined actions which run after all other actions
