Pasan Tennakoon updated OLINGO-1569:
------------------------------------
Description:
Olingo Entity Streaming support allows us to process entities chunk by chunk.
Only after all the chunks are processed we get to know the entire results and
{*}its count{*}.
However *entityCollectionIntoStream* method in *ODataXmlSerializer* and
*ODataJsonSerializer* calls *writeCount* method before calling *writeEntitySet*
method. *writeEntitySet* method is the method which calls the iterator
*(EntityIterator)* where we process the entities one by one. Calling
*writeCount* method before calling the *writeEntitySet* method means we need to
know the count of the result before we process and get to know the final
result.
