NIO2 FIleContentType Provider in Java, Groovy & Kotlin
As I like to say, java.nio.file is like a big wooden crate with some
diagrams, but it does not actually contain any useful content.
I had to solve a problem yesterday and wrote this
https://github.com/ysb33r/nio2-filedetector-tika. It will detect the
content type of a file, bu actually inspecting the first couple of bytes
of a file rather than guessing it from the file extension. It uses
Apache Tika underneath to do the real work. This allows the
java.nio.file.FIles.probeFIieContent(Path) method to actually do
something useful and not just return null. \o/
I am posting this here as the repo contains three functionally
equivalant implementations - Java, Groovy & Kotlin. (The published
artifact on BIntray is the Java one, simply because I did not want to
add an additional dependency for such a small implementation). At some
stage I'll get around to comparing the performance of the three
implementations
This will form part of something else I want to do is showing how to
write NIO2 providers in alternative JVM languages.
In the mean-time this might be of interest to those who would like to
compare implementations.
