ComponentConfiguration

public class ComponentConfiguration extends Object
Simple configuration class storing properties as key with defined property values as values in a Map. As a map cannot contain duplicate keys the first use of a key can not be replaced. If a key is used twice a {@link java.lang.IllegalArgumentException} will be thrown.
