- - ### Method Detail

    - #### getClassName

          String getClassName()

      Return the name of the underlying class.

    - #### isInterface

          boolean isInterface()

      Return whether the underlying class represents an interface.

    - #### isAbstract

          boolean isAbstract()

      Return whether the underlying class is marked as abstract.

    - #### isConcrete

          boolean isConcrete()

      Return whether the underlying class represents a concrete class, i.e. neither an interface nor an abstract class.

    - #### isFinal

          boolean isFinal()

      Return whether the underlying class is marked as 'final'.

    - #### isIndependent

          boolean isIndependent()

      Determine whether the underlying class is independent, i.e. whether it is a top-level class or a nested class (static inner class) that can be constructed independent from an enclosing class.

    - #### hasEnclosingClass

          boolean hasEnclosingClass()

      Return whether the underlying class has an enclosing class (i.e. the underlying class is an inner/nested class or a local class within a method).

      If this method returns `false`, then the underlying class is a top-level class.

    - #### getEnclosingClassName

          String getEnclosingClassName()

      Return the name of the enclosing class of the underlying class, or `null` if the underlying class is a top-level class.

    - #### hasSuperClass

          boolean hasSuperClass()

      Return whether the underlying class has a super class.

    - #### getSuperClassName

          String getSuperClassName()

      Return the name of the super class of the underlying class, or `null` if there is no super class defined.

    - #### getInterfaceNames

          String[] getInterfaceNames()

      Return the names of all interfaces that the underlying class implements, or an empty array if there are none.

    - #### getMemberClassNames

          String[] getMemberClassNames()

      Return the names of all classes declared as members of the class represented by this ClassMetadata object. This includes public, protected, default (package) access, and private classes and interfaces declared by the class, but excludes inherited classes and interfaces. An empty array is returned if no member classes or interfaces exist.
