byte_buffer

An implementation of Java ByteBuffer in C.

• Documentation already available :)
  • https://docs.oracle.com/javase/8/docs/api/java/nio/ByteBuffer.html
• buffer required to be freed by bb_destroy
• assert is used to replace Java exception
• Aligns to most methods in Java ByteBuffer, except:
  • allocate is replaced by bb_create to emphasize the need for bb_destroy
  • hasArray, allocateDirect, isDirect are not implemented as they are Java specific for native allocation
  • duplication and slice were intentionally omitted as they would impose the order of bb_destroy
  • getChar and putChar are not implemented as there is no equivalent of Java Char in C
  • get/put for Float/Double are not implemented as their byte-sizes are uncertain in C
