Library: Util
Package: Configuration
Header: Poco/Util/ConfigurationView.h
This configuration implements a "view" into a sub-hierarchy of another configuration.
For example, given a configuration with the following properties:
config.value1 config.value2 config.sub.value1 config.sub.value2
and a ConfigurationView with the prefix "config", then the above properties will be available via the view as
value1 value2 sub.value1 sub.value2
A ConfigurationView is most useful in combination with a LayeredConfiguration.
If a property is not found in the view, it is searched in the original configuration. Given the above example configuration, the property named "config.value1" will still be found in the view.
The main reason for this is that placeholder expansion (${property}) still works as expected given a ConfigurationView.

Creates the ConfigurationView. The ConfigurationView does not take ownership of the passed configuration.
