Method Detail

ensure

long ensure(long key)

Ensures that there is a mapping from the given key 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.

Parameters:

key - the key

Returns:

address of value block

get

long get(long key)

Returns the address of the value block mapped by the given key.

Parameters:

key - the key

Returns:

address of the value block or MemoryAllocator.NULL_ADDRESS if no mapping for key exists.

remove

boolean remove(long key)

Removes the mapping for the given key.

Parameters:

key - the key

Returns:

true if a mapping existed and was removed, false otherwise

cursor

HashSlotCursor8byteKey cursor()

Returns a cursor over all assigned slots in this array.
