Inherited properties

Name Type Inherited from Description
description Accessor ReadOnly string Tool Get the localized description string from this Tool's class
description Accessor StaticReadOnly string Tool Get the localized description for this Tool class. This returns the value of "tools." + this.toolId + ".description" from
its registered Namespace (e.g. "en/MyApp.json"). If that key is not in the localization namespace,
Tool.flyover is returned.
englishKeyin Accessor StaticReadOnly string Tool Get the English keyin string for this Tool class. This returns the value of "tools." + this.toolId + ".keyin" from
its registered Namespace (e.g. "en/MyApp.json").
flyover Accessor ReadOnly string Tool Get the localized flyover string from this Tool's class
flyover Accessor StaticReadOnly string Tool Get the localized flyover for this Tool class. This returns the value of "tools." + this.toolId + ".flyover" from
its registered Namespace (e.g. "en/MyApp.json"). If that key is not in the localization namespace,
Tool.keyin is returned.
hidden Static boolean Tool If true, this Tool will not appear in the list from ToolRegistry.getToolList.
i18n Static I18N Tool The internationalization services instance used to translate strings from the namespace.
iconSpec Accessor ReadOnly string Tool Get the iconSpec from this Tool's class.
iconSpec Static string Tool The icon for this Tool.
keyin Accessor ReadOnly string Tool Get the localized keyin string from this Tool's class
keyin Accessor StaticReadOnly string Tool Get the localized keyin string for this Tool class. This returns the value of "tools." + this.toolId + ".keyin" from
its registered Namespace (e.g. "en/MyApp.json").
maxArgs Accessor StaticReadOnly number | undefined Tool The maximum number of arguments allowed by Tool.parseAndRun, or undefined if there is no maximum.
If subclasses override Tool.parseAndRun, they should also override this method to indicate the maximum
number of arguments their implementation expects.
minArgs Accessor StaticReadOnly number Tool The minimum number of arguments allowed by Tool.parseAndRun. If subclasses override Tool.parseAndRun, they should also
override this method to indicate the minimum number of arguments their implementation expects. UI controls can use
this information to ensure the tool has enough information to execute.
namespace Static I18NNamespace Tool The I18NNamespace that provides localized strings for this Tool.
toolId Accessor ReadOnly string Tool Get the toolId string for this Tool class. This string is used to identify the Tool in the ToolRegistry and is used to localize
the keyin, description, etc. from the current locale.
toolId Static string Tool The unique string that identifies this tool.
