How to get FileChannel from resource (original) (raw)

Sherman, yes, you are right. That's not what I'm looking for.

This would be slower, than reading the stream directly, because the underlying byte array will be copied 2 times by BufferedInputStream# + Channels.ReadableByteChannelImpl#read(), ... but maybe not, because looping BufferedInputStream#readChar() could be slower than twice System.arraycopy().

Anyway, I'm looking for a DirectBuffer directly from a resource file. So I think there is something missing: URL.openChannel() or Class#getResourceAsChannel()

Maybe there is a way to get a RamdomAccessFile from URL to get the Channel from. Anybody knows ?

Should I file a bug ? Somebody any objections ?

You can use java.nio.channels.Channels.newChannel() to get a ReadableByteChannel on top of the InputStream you get from URL.openStream()...

but if my guess of what you want to do is correct, that channel is probably not that useful:-) Sherman Ulf Zibis wrote: Hi all

there is a { URL getResource(String name) } in class Class. Does anybody know, how to get a java.nio.channels.Channel or FileChannel from this URL? Thanks in advance, -Ulf
