API Reference › core-frontend› Tools › InputCollector

InputCollector Class

The InputCollector class can be used to implement a command for gathering input (ex. get a distance by snapping to 2 points) without affecting the state of the active primitive tool. An InputCollector will suspend the active PrimitiveTool and can be suspended by a ViewTool.

Inherited properties

Name Type Inherited from Description
description Accessor Inherited ReadOnly string InteractiveTool Get the localized description string from this Tool's class
description Accessor Static Inherited ReadOnly string InteractiveTool 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 Inherited ReadOnly string InteractiveTool 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 Inherited ReadOnly string InteractiveTool Get the localized flyover string from this Tool's class
flyover Accessor Static Inherited ReadOnly string InteractiveTool 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 Inherited boolean InteractiveTool If true, this Tool will not appear in the list from getToolList.
iconSpec Accessor Inherited ReadOnly string InteractiveTool Get the iconSpec from this Tool's class.
iconSpec Static Inherited string InteractiveTool The icon for this Tool.
isControlDown Accessor Inherited ReadOnly boolean InteractiveTool Convenience method to check whether control key is currently down without needing a button event.
isDynamicsStarted Accessor Inherited ReadOnly boolean InteractiveTool Call to find out if dynamics are currently active.
keyin Accessor Inherited ReadOnly string InteractiveTool Get the localized keyin string from this Tool's class
keyin Accessor Static Inherited ReadOnly string InteractiveTool 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 Inherited ReadOnly undefined | number InteractiveTool 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 Inherited ReadOnly number InteractiveTool 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 Inherited string InteractiveTool The namespace that provides localized strings for this Tool.
receivedDownEvent Inherited boolean InteractiveTool Used to avoid sending tools up events for which they did not receive the down event.
toolId Accessor Inherited ReadOnly string InteractiveTool 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 Inherited string InteractiveTool The unique string that identifies this tool.
