Class: Namespace ./src/peak/config/config_components.py

Traverse to another property namespace

Use this in .ini files (e.g. '__main__. = config.Namespace("environ.")') to create a rule that looks up undefined properties in another property namespace.

Or, use this as a way to treat a property namespace as a mapping object:

        myNS = config.Namespace("some.prefix", aComponent)
        myNS['spam.bayes']              # property 'some.prefix.spam.bayes'
        myNS.get('something',default)   # property 'some.prefix.something'

Or use this in a component class to allow traversing to a property space:

        class MyClass(binding.Component):

            appConfig = binding.Make(
                config.Namespace('MyClass.conf')
            )

            something = binding.Obtain('appConfig/foo.bar.baz')

In the example above, something will be the component's value for the property MyClass.conf.foo.bar.baz. Note that you may not traverse to names beginning with an _, and traversing to the name get will give you the namespace's get method, not the get property in the namespace. To obtain the get property, or properties beginning with _, you must use the mapping style of access, as shown above.
