public final class AMD64ArrayCopyWithConversionsOp
extends AMD64ComplexVectorOp

Arraycopy operation for arbitrary source and destination arrays, with arbitrary byte offset, with support for arbitrary compression and inflation of 8 bit, 16 bit or 32 bit array elements.

CAUTION: the compression implementation assumes that the upper bytes of char/int values to be compressed are zero. If this assumption is broken, compression will yield incorrect results!
