GetDescription()

std::string DekiEditor::CompoundCommand::GetDescription ( ) const

inlineoverridevirtual

Human-readable description for UI display.

Implements DekiEditor::Command.

Execute()

void DekiEditor::CompoundCommand::Execute ( )

inlineoverridevirtual

Execute the command.

Implements DekiEditor::Command.

Undo()

void DekiEditor::CompoundCommand::Undo ( )

inlineoverridevirtual

Undo the command.

Implements DekiEditor::Command.

Redo()

void DekiEditor::CompoundCommand::Redo ( )

inlineoverridevirtual

Redo the command (default: calls Execute).

Reimplemented from DekiEditor::Command.

ReferencesAny()

bool DekiEditor::CompoundCommand::ReferencesAny ( const DeadMemory & dead ) const

inlineoverridevirtual

Report whether this command holds a raw pointer to anything in dead.

CommandHistory calls this when the scene is about to free objects, and discards any command that answers true — running Undo()/Redo() on a command whose target has been freed is a use-after-free.

The default is false, which is correct for commands that address their target by value or by id. Any command storing a DekiObject*, DekiComponent*, or Scene* MUST override this; see the implementations in src/core/commands/ for the pattern.

Reimplemented from DekiEditor::Command.
