HashSlotArray16byteKeyImpl(key1, key2) to a slot in the array.
The abs of the returned integer is the address of the slot's value block.
The returned integer is positive if a new slot had to be assigned and negative
if the slot was already assigned.
Whenever this method returns a positive value, the caller must ensure that the null-sentinel value
at the returned address is overwritten with a non-null-sentinel value.ensure in interface HashSlotArray16byteKeyensure in class HashSlotArray16byteKeyImplkey1 - key part 1key2 - key part 2public long get(long key1,
