Java API and Off-heap memory

[jean safar]

Hi, 

As I was looking at the Java API to use the library I could not find any place to plug in my double arrays that are already stored in Direct Buffers off-heap. 

Rather than going back to double[] from DirectBuffer and potentially also incur a cost when going back through JNI, Yeppp could directly use the Direct Buffers. 

Is anything being done toward that or is it not worth it performance-wise? 

Best regards

Hi Jean,

Yeppp! does not provide a Java interface to operate on DirectBuffers, and there are no plans for it either.

We don't know what could be the performance impact if such interface was supported.

Regards,
