| xref:BloombergLP/bdlcc/SkipList_PoolUtil/allocate.adoc[`allocate`] 
| Reserve sufficient space for a node at the specified `level` from the specified `poolManager`, and return the address of the reserved memory.
| xref:BloombergLP/bdlcc/SkipList_PoolUtil/createPoolManager.adoc[`createPoolManager`] 
| Create a new pooled node allocator that manages nodes up to the specified `numLevels` as described by the specified `objectSizes`. For `i` in `[0, numLevels)]`, a node at level `i` will have size `objectSizes[i]` bytes. Use the specified `basicAllocator` to supply memory. Return the address of the new allocator. Note that the behavior is undefined if `basicAllocator` is 0.
| xref:BloombergLP/bdlcc/SkipList_PoolUtil/deallocate.adoc[`deallocate`] 
| Return the node at the specified `address` to the specified `poolManager`. The behavior is undefined if `address` was not allocated from `poolManager`.
| xref:BloombergLP/bdlcc/SkipList_PoolUtil/deletePoolManager.adoc[`deletePoolManager`] 
| Destroy the specified `poolManager` which was allocated from the specified `basicAllocator`. The behavior is undefined if `poolManager` was not allocated from `basicAllocator`.
