Detailed Description

A light-weight replacement for ToolSvc for ROOT analysis.

In order to allow tools to find each other through ToolHandles, just like in Athena, we need a global registry of all of the tools that the user instantiates in his/her job.

This class does exactly this. All created dual-use tools register themselves in it, so that other components could later on find them.

      return remove( tool->name() );
   }

remove() [2/2]

StatusCode asg::ToolStore::remove ( const std::string &  name )

static

Remove a tool with a given name from the store.
