[Insight-users] Why are getBufferAs* methods not available in Java?

[Zamir Khan]

Hi Dan,

Thank you for investigating and confirming the issue. I would like to look
into this more at some point, but that will have to wait until some time
opens up. It'd also be my first experience with SWIG, but I consider that a
learning opportunity. For now that these functions are missing represents
an inconvenience for me rather than a showstopper.

Thanks,
Zamir
