Constructor & Destructor Documentation

Member Function Documentation

◆ clone()

std::unique_ptr<editor_action> editor::editor_action_paste::clone ( ) const

overridevirtual

Action cloning.

Implements editor::editor_action.

◆ extend()

void editor::editor_action_paste::extend	(	const editor_map &	map,
		const std::set< map_location > &	locs
	)

overridevirtual

The crux of the extendable contract.

This member function must be implemented so that the undo behavior is consistent, exactly the same as would be with separate undo actions for every part of the drag.

Implements editor::editor_action_extendable.

Definition at line 181 of file action.cpp.

◆ get_name()

const std::string& editor::editor_action_paste::get_name ( ) const

overridevirtual

Returns: a short name of this action type, defaults to unknown

Reimplemented from editor::editor_action_extendable.

◆ perform()

std::unique_ptr< editor_action > editor::editor_action_paste::perform ( map_context & mc ) const

overridevirtual

Perform the action, returning an undo action that, when performed, shall reverse any effects of this action.

The undo action object is owned by the caller. Default behavior is to create a whole-map undo, call the perform_without_undo function and return the undo object.

Reimplemented from editor::editor_action.

Definition at line 186 of file action.cpp.
