/**
* 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.
