Currently I have it set up to MMAP the files. I am still using Apache
EndianUtils for reading Little Endian values. I am not sure of the
advantage of calling foo.order(ByteOrder.LITTLE_ENDIAN) instead of using
the EndianUtils, (...snip...)
I noticed that you switched to
ByteBuffer.order(ByteOrder.LITTLE_ENDIAN), thanks. For the record, the
advantages are:
* No need for external libraries, since ByteBuffer is bundled in JDK 1.4+
* No need for additional API, since the same set of existing methods
work in both cases
* Potentially order of magnitude faster, since ByteBuffer.get*() with
Little Endian order maps directly to a single CPU instruction on
Intel processors, while I guess (but did not verified) that
EndianUtils performs arithmetic operations for achieving equivalent
result.
