public class HashSlotArray8byteKeyImpl extends HashSlotArrayBase implements HashSlotArray8byteKey
HashSlotArray8byteKey as a restriction of HashSlotArrayBase
to a case where just key1 is used.
This class uses the first 8 bytes of the value block for the unassigned sentinel.
It is the responsibility of the caller to ensure that the unassigned sentinel
is overwritten with a non-sentinel value as soon as a new slot is assigned (after calling
ensure(long) and getting a positive return value).
For the same reason this class must not be instantiated with zero value length. Use
HashSlotArray8byteKeyNoValue as a zero-length key implementation.

public long ensure(long key)
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-sentinel value.ensure in interface HashSlotArray8byteKeykey - the keypublic long get(long key)
