GraphHistoryOptions

Options for the undo/redo command manager owned by <Diagram history>.

Beyond these options, any single write can be excluded from the undo stack by passing { skipHistory: true } as the setter's metadata (e.g. setCellData(id, updater, { skipHistory: true })) — the command manager drops commands carrying that flag before recording them.

Properties

filterCommand?

readonly optional filterCommand?: (params) => boolean;

Return false to skip a command (it won't be recorded on the undo stack).

Parameters
