No, no, no.

[quote]In computing, the term endian or endianness refers to the ordering of individually addressable sub-components within the representation of a larger data item as stored in external memory (or, sometimes, as sent on a serial connection).[/quote]
That is, the endianness only applies to the internal ordering of the sub-components of the data representation. It does not apply to the ordering of these subcomponents within the data representation itself.
The order of your data stream itself is not changed anywhere, or by anyone. It will stay as it is. If your data is written in the order parameter1, parameter2, parameter3, they will stay in that order and should be read back in that order, no matter what endianness was used in writing. The endianness only applies to the byte ordering within these parameters.
Reflect a bit on what would happen if it applied to the whole data representation in the case of working with a large data stream (say, a HD video streaming service). Do you really think that in case a little-endian prepresentation would be used, the whole datastream needs to be transferred to the client before that client can start processing it? You think that the first frame of the video on that stream will be at the end of the stream? That would not make a very good streaming service, would it?
