inherited

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 )

inherited

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. :(

make a service with the given configuration

\warn This is mostly meant as a low level interface to be used in unit tests and internally by framework functions that manage services. As a user you should mostly rely on the python configuration or on passing the AsgServiceConfig object to your framework, which will then create and manage the service for you.

\warn Regardless of which function you use, the memory management and cleanup of services differs between stand-alone use and Athena. In EventLoop you receive an owning pointer/handle that can be shared with other users and will release the service when the last reference is deleted. In Athena the framework itself will hold on to the service (or at least its configuration) and release it at the end of the job, even if no user code references it. As a user you should not rely on the service still being around after you destroy the last reference, or on the service being around after framework teardown has started.
