Member Function Documentation

insertedNode()

Node * Model::NodeOwningCommand::insertedNode ( ) const

overridevirtual

Returns the node that this command inserted into the tree, or nullptr if no node was inserted.

The default implementaion returns nullptr. Reimplement this in commands that own a node.

Reimplemented from Model::UndoCommand.

moveNodes()

void Model::NodeOwningCommand::moveNodes ( Node *  root, NodeIdMap &  source, NodeIdMap &  target  )

private

owned()

Node * Model::NodeOwningCommand::owned ( ) const

overridevirtual

Returns the node owned by this command or nullptr if no node is owned.

Nodes which are owned should be deleted by the command when it is deleted.

Reimplemented from Model::UndoCommand.

redo()

void Model::NodeOwningCommand::redo ( )

overridevirtual

Reimplemented from Model::UndoCommand.

Reimplemented in Model::ListRemove, Model::ListPut, Model::ListInsert, and Model::CompositeNodeChangeChild.

removedNode()

Node * Model::NodeOwningCommand::removedNode ( ) const

overridevirtual

Returns the node that this command removed from the tree, or nullptr if no node was removed.

The default implementaion returns nullptr. Reimplement this in commands that own a node.

Reimplemented from Model::UndoCommand.

undo()

void Model::NodeOwningCommand::undo ( )

overridevirtual

Reimplemented from Model::UndoCommand.

Reimplemented in Model::ListRemove, Model::ListPut, Model::ListInsert, and Model::CompositeNodeChangeChild.
