Inherited methods

Name Inherited from Description
parseAndRun(..._args: string[]): Promise<boolean> Tool Run this instance of a tool using a series of string arguments.
run(..._args: any[]): Promise<boolean> Tool Run this instance of a Tool.
register(namespace?: string): void Static Tool Register this Tool class with the ToolRegistry.

Properties

Name Type Description
isControlDown Accessor ReadOnly boolean Convenience method to check whether control key is currently down without needing a button event.  
isDynamicsStarted Accessor ReadOnly boolean Call to find out if dynamics are currently active.  
receivedDownEvent boolean Used to avoid sending tools up events for which they did not receive the down event.  

Inherited properties

Name Type Inherited from Description
description Accessor ReadOnly string Tool Get the localized description string from this Tool's class
description Accessor Static ReadOnly 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,
flyover is returned.
englishKeyin Accessor Static ReadOnly 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 Static ReadOnly 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,
keyin is returned.
hidden Static boolean Tool If true, this Tool will not appear in the list from getToolList.
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 Static ReadOnly 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 Static ReadOnly undefined | number Tool The maximum number of arguments allowed by parseAndRun, or undefined if there is no maximum.
If subclasses override parseAndRun, they should also override this method to indicate the maximum
number of arguments their implementation expects.
minArgs Accessor Static ReadOnly number Tool The minimum number of arguments allowed by parseAndRun. If subclasses override 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 string Tool The namespace 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.
