any reason why multiple ranged-reads not currently supported in rados-java?

any reason why multiple ranged-reads not currently supported in rados-java?

[Daniel Hsueh]

Hello,

I'm looking at the Java librados JNA-based API, and note that ranged
reads (rados_create_read_op, rados_release_read_op,
rados_read_op_read, rados_read_op_operate) are not currently
accessible to a Java program.

Are there any difficulties in implementing access to these calls?  If
it is straightforward, I'll implement them myself and contribute back
to the github repository.

Thank you.

My guess is this was just an oversight.  A patch / pull request wiring 
this up would be awesome.

Thanks!

Indeed. I was a bit lazy and implemented what I needed at the time of 
writing rados-java.
