Hi
No, I ask it with "*markSupported
<http://docs.oracle.com/javase/7/docs/api/java/io/InputStream.html#markSupported()>*
()" function and it says "NO".
No recreation.
The code test is very simple:
InputStream inputsbust = content.getContentStream();
System.out.println(" mark and reset inputStream ?
"+(inputsbust.markSupported()?"YES":"NO"));
System.out.println(" 1 mime : " + tika.detect(inputsbust));
System.out.println(" 2 mime : " + tika.detect(inputsbust));
byte[] bytes = IOUtils.toByteArray(inputsbust);
System.out.println(" 3 mime : " + tika.detect(bytes));
System.out.println(" 3.2 mime : " + tika.detect(bytes));
The result:
mark and reset of inputStream ? NO
1 mime : application/pdf
2 mime : application/octet-stream
3 mime : application/octet-stream
3.2 mime : application/octet-stream
If i put the 5th line ("byte[] bytes = IOUtils.toByteArray(inputsbust);")
as second line the result is:
mark and reset of inputStream ? NO
1 mime : application/octet-stream
2 mime : application/octet-stream
3 mime : application/pdf
3.2 mime : application/pdf
I hope it helps
Thanks
