◆ configureComponentExpert()

add component configuration to configuration service (expert only)

In Athena we are not creating components (we leave that to the proper Athena services), but instead we load the configuration values up first, then ask for the component to be created the normal way. This makes sure that if we dump the configuration it will include this component, and as a bonus it avoids the whole issue of having to deal with Athena factory functions.

◆ createPrivateTool()

StatusCode asg::AsgComponentConfig::createPrivateTool	(	const std::string &	name,
		const std::string &	toolType
	)

create a private tool of the given name and type

This is the only way you can configure tool properties through AsgComponentConfig: You need to add it the tool to the component configuration and then you can set individual properties on the tool, using the property name "tool.property".

If you want to add a subtool for a tool, you can do this by calling it "tool.subtool". Note that you will have to create both the tool and the subtool this way, i.e. you can't configure a subtool without also configuring the tool that owns it.

You can apply this to tools held by either ToolHandle or asg::AnaToolHandle, but if you configure a tool held by an AnaToolHandle this way it will completely replace teh tool configuration done in the component itself.

The calling convention is somewhat inverted compared to setTypeAndName() calls, but otherwise they would be inverted compared to the setProperty() calls. :(
