java - Constructor this() unnecessary? -

-

there class u1 extending class u. class u empty...

in constructor of u1 there first line, calling constructor of superclass...

public u1(plate plate, int order) {    super(plate, order); ...  }

now want delete class u1 , in class u whatever done in u1 far... so, not need call constructor of superclass since class u not gonna have superclass...

is this(plate, order) unnecessary , can omit it?

this how constructor of u gonna like:

public u(plate plate, int order)     {        this(plate, order);     ...      }

it unnecessary , expect results in stack overflow, because call constructor within constructor.

Decoding a Python 2 `tempfile` with python-future -

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
