ConfigurationProperties (smartics-properties-config 0.4.0-SNAPSHOT API)

Use getProperties(Class) to obtain an implementation of an interface that provides access to the property values through its methods. This is the recommended way to deal with properties.
Use one of the getProperty methods. This access may be more convenient, if the context deals with property keys that are provided by the user (e.g. from an UI).

Implementation Notes:: This interface is intended to be implemented by service providers. API users are intended to us this interface to access properties. For details on creating instances of classes implementing this interface please refer to de.smartics.properties.api.config.
