Y, this makes sense.
Detector detector = TikaConfig.getDefaultConfig().getDetector();
File file = new File("testPDFVarious.pdf");
try (FileInputStream is = new FileInputStream(file)) {
try (InputStream tis = TikaInputStream.get(is)) {
System.out.println("length: " + file.length());
System.out.println("avail before: " + tis.available());
System.out.println("DETECTED: " + detector.detect(tis, new
Metadata()));
System.out.println("avail after tis: " + tis.available());
System.out.println("avail after is: " + is.available());
}
}
length: 205491
avail before: 205491
DETECTED: application/pdf
avail after tis: 205491
avail after is: 139955
The original input stream is not buffered, and so there is no way to reset it,
so y, the detector has to read quite a few bytes to do detection.
Note, though, that the TikaInputStream or even a BufferedInputStream will be
correctly reset and will have all bytes available.
Btw, it is better to call TikaInputStream.get() directly on the file. If a
parser needs to copy the original inputstream to a temp file, it can avoid that
copy, if you've created your TikaInputSTream directly from the file.
TikaInputStream tis = TikaInputStream.get(file)

Hi Samuel,
I myself haven’t had a chance to look into this yet - maybe someone else on the
dev list?
Cheers,
Chris
