If subclasses override ArrowTool.parseAndRun, they should alsooverride this method to indicate the minimum number of arguments their implementation expects. UI controls can usethis information to ensure the tool has enough information to execute. namespace Static I18NNamespace ArrowTool The I18NNamespace that provides localized strings for this Tool. receivedDownEvent boolean ArrowTool Used to avoid sending tools up events for which they did not receive the down event. targetIsLocked boolean ArrowTool targetModelId Accessor undefined | string ArrowTool targetView undefined | Viewport ArrowTool The viewport within which the tool operates. toolId Accessor ReadOnly string ArrowTool Get the toolId string for this Tool class. This string is used to identify the Tool in the ToolRegistry and is used to localizethe keyin, description, etc. from the current locale. toolKey Static string ArrowTool Defined in markup/src/RedlineTool.ts Line 354 Last Updated: 12 June, 2024
