register(namespace?: I18NNamespace, i18n?: I18N): void Static PrimitiveTool Register this Tool class with the ToolRegistry. Properties Name Type Description _isSelectByPoints Protected boolean _isSuspended Protected boolean _points ProtectedReadonly Point3d[] hidden Static boolean If true, this Tool will not appear in the list from ToolRegistry.getToolList. iconSpec Static string The icon for this Tool. selectionMethod Accessor SelectionMethod selectionMode Accessor SelectionMode toolId Static string The unique string that identifies this tool. Inherited properties Name Type Inherited from Description description Accessor ReadOnly string PrimitiveTool Get the localized description string from this Tool's class description Accessor StaticReadOnly string PrimitiveTool Get the localized description for this Tool class. This returns the value of "tools." + this.toolId + ".description" fromits registered Namespace (e.g. "en/MyApp.json"). If that key is not in the localization namespace,PrimitiveTool.flyover is returned. englishKeyin Accessor StaticReadOnly string PrimitiveTool Get the English keyin string for this Tool class. This returns the value of "tools." + this.toolId + ".keyin" fromits registered Namespace (e.g. "en/MyApp.json"). flyover Accessor ReadOnly string PrimitiveTool Get the localized flyover string from this Tool's class flyover Accessor StaticReadOnly string PrimitiveTool Get the localized flyover for this Tool class. This returns the value of "tools." + this.toolId + ".flyover" fromits registered Namespace (e.g. "en/MyApp.json"). If that key is not in the localization namespace,PrimitiveTool.keyin is returned. i18n Static I18N PrimitiveTool The internationalization services instance used to translate strings from the namespace. iconSpec Accessor ReadOnly string PrimitiveTool Get the iconSpec from this Tool's class. iModel Accessor ReadOnly IModelConnection PrimitiveTool Get the iModel on which this tool operates. isControlDown Accessor ReadOnly boolean PrimitiveTool Convenience method to check whether control key is currently down without needing a button event. isDynamicsStarted Accessor ReadOnly boolean PrimitiveTool Call to find out if dynamics are currently active. keyin Accessor ReadOnly string PrimitiveTool Get the localized keyin string from this Tool's class keyin Accessor StaticReadOnly string PrimitiveTool Get the localized keyin string for this Tool class. This returns the value of "tools." + this.toolId + ".keyin" fromits registered Namespace (e.g. "en/MyApp.json"). maxArgs Accessor StaticReadOnly undefined | number PrimitiveTool The maximum number of arguments allowed by PrimitiveTool.parseAndRun, or undefined if there is no maximum.If subclasses override PrimitiveTool.parseAndRun, they should also override this method to indicate the maximumnumber of arguments their implementation expects. minArgs Accessor StaticReadOnly number PrimitiveTool The minimum number of arguments allowed by PrimitiveTool.parseAndRun. If subclasses override PrimitiveTool.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 PrimitiveTool The I18NNamespace that provides localized strings for this Tool. receivedDownEvent boolean PrimitiveTool Used to avoid sending tools up events for which they did not receive the down event. targetIsLocked boolean PrimitiveTool targetModelId Accessor undefined | string PrimitiveTool targetView undefined | Viewport PrimitiveTool The viewport within which the tool operates. toolId Accessor ReadOnly string PrimitiveTool 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.
