Interface ConfigurationProperty

public interface ConfigurationProperty

A configuration property.

A configuration property is identified by a configuration key which is composed of a name and a collection of parameters defining the context for which a property value is defined. This means that for a given property name, multiple values can be defined in a configuration source for different contexts.
