    • isMethodImplementedBy

      public static boolean isMethodImplementedBy(Class<?> target, Object instance, String methodName, Class<?>... params)
      Checks whether the given method is implemented by the given target class. Returns false when implemented by a subclass. For example: 
          interface A {
        default void foo() {}
        default void bar() {}
    }
    class B implements A {
      public void foo() {}
    }

    // false, because foo is implemented by B
    isMethodImplementedBy(A.class, new B(), "foo")

    // true, because B inherits the implementation of bar from A
    isMethodImplementedBy(A.class, new B(), "bar")
      Parameters:
      target - The target class.
      instance - The instance to check.
      methodName - The name of the method.
      params - The parameter types of the method.
      Returns:
      true when the method is implemented by the target class.

      Parameters:
      value - Value to parse.
      Returns:
      The integer represented by the string, or null when the string does not represent a valid integer.

    • parseLongOrNull

      public static Long parseLongOrNull(String value)
      Parses the value as a long, if possible, or returns null if it cannot be parsed.
