Method Details
-
getUnderlyingSource
ObjectArraySource<K> getUnderlyingSource() -
getCurrentSsm
Get the current SSM at the specified key. This does not permute it in any way.- Parameters:
key
- the key to get the ssm for.- Returns:
- the SSM
-
getOrCreate
Get the ssm at the specified key, creating one if none existed. This method will update the current previous tracking state of the SSM.- Parameters:
key
- the key to get the ssm for.- Returns:
- the SSM at the key, or a new one.
-
clear
void clear(long key) Set the SSM at the specified key to null- Parameters:
key
- the key to get the ssm for.
-
ensureCapacity
void ensureCapacity(long capacity) Ensure the source has at least `capacity` capacity- Parameters:
capacity
- the capacity to ensure.
-
clearDeltas
Clear out any tracked deltas from recent computations.- Parameters:
indices
- the set of indices to clear deltas for.
