 * This is the back-port for the according interface of Java 1.8+.

 * ATTENTION:

 * The Java 1.8+ version of this interface also defines default methods that can NOT be supported in prior
 * java versions. Therefore, mmm-util-core offers helper methods that give similar features.
 * However, we strongly recommend that you update your project to Java 1.8+ to make use of closures (lambda
 * expressions) and other benefits.
