FSTBinaryOffheapMap Android support? #263

Open Wavesonics opened 6 years ago

Wavesonics commented 6 years ago

So it looks like the off heap map part of the library suffers from the same problem that the normal FST serialization stuff suffered from in the beginning: relying on the sun Unsafe class

Is there any chance we could get a similar solution that the Serialization stuff uses to get these working on Android?

one needs to back offheap map using bytebuffers. This is currently not implemented. Basically you need to have a ByteBuffer backed implementation for ByteSource
