Method Detail

• getAllInterfaces

  public static Class<?>[] getAllInterfaces(Class<?> cls)

  Gets an array of Class objects representing all interfaces implemented by the given class and its superclasses.

  The order is determined by looking through each interface in turn as declared in the source file and following its hierarchy up. Then each superclass is considered in the same way. Later duplicates are ignored, so the order is maintained.

  Note: Implementation of this method was "borrowed" from Apache Commons Lang to avoid a dependency.

  Parameters:

  cls - the class to look up, may be null

  Returns:

  an array of Class objects representing all interfaces implemented by the given class and its superclasses or null if input class is null.
