 /**
  * An informative annotation type used to indicate that an interface
  * type declaration is intended to be a <i>functional interface</i> as
  * defined by the Java Language Specification.
  *
  * Conceptually, a functional interface has exactly one abstract
  * method.  Since {@linkplain java.lang.reflect.Method#isDefault()
  * default methods} have an implementation, they are not abstract.  If
  * an interface declares an abstract method overriding one of the
  * public methods of {@code java.lang.Object}, that also does
  * <em>not</em> count toward the interface's abstract method count
  * since any implementation of the interface will have an
  * implementation from {@code java.lang.Object} or elsewhere.
  *
  * <p>Note that instances of functional interfaces can be created with
  * lambda expressions, method references, or constructor references.
  *
  * <p>If a type is annotated with this annotation type, compilers are
  * required to generate an error message unless:
  *
  * <ul>
  * <li> The type is an interface type and not an annotation type, enum, or class.
  * <li> The annotated type satisfies the requirements of a functional interface.
  * </ul>
  *
  * <p>However, the compiler will treat any interface meeting the
  * definition of a functional interface as a functional interface
  * regardless of whether or not a {@code FunctionalInterface}
  * annotation is present on the interface declaration.
