    • parseBool

      public static boolean parseBool(@Nullable Object aObject)
      Try to interpret the passed object as boolean. This works only if the passed object is either a String or a Boolean.
      Parameters:
      aObject - The object to be interpreted. May be null.
      Returns:
      false if the passed object cannot be interpreted as a boolean.

    • parseBool

      public static boolean parseBool(@Nullable Object aObject, boolean bDefault)
      Try to interpret the passed object as boolean. This works only if the passed object is either a String or a Boolean.
      Parameters:
      aObject - The object to be interpreted. May be null.
      bDefault - The default value to be returned, if the object cannot be interpreted.
      Returns:
      The boolean representation or the default value if the passed object cannot be interpreted as a boolean.

    • parseBool

      public static boolean parseBool(@Nullable String sStr)
      Parse the given String as boolean value. All values that are equal to "true" (ignoring case) will result in true return values. All other values result in false return values. This method is equal to Boolean.parseBoolean(String)
      Parameters:
      sStr - The string to be interpreted. May be null.
      Returns:
      true if the passed string matches "true" (ignoring case), false otherwise.
