public static class EnumerationUtils.InstanceSearchSpace
extends TreeMap<Long,TreeMap<Integer,LinkedList<CloudInstance>>>
Data structure representing a projected search space for
VM instances as node's memory mapped to further maps with
the node's numbers of cores for the given memory
mapped to a list of unique object of type CloudInstance
which have this corresponding characteristics (memory and cores).
The higher layer keep the memory since is more significant
for the program compilation. The lower map level contains
the different options for number of core for the memory that
this map data structure is being mapped to. The last layer
of LinkedLists represents the unique VM instances in lists
since the memory - cores combinations is often not unique.
The CloudInstance objects are unique over the whole
set of lists within this lowest level of the search space.
This representation allows compact storing of VM instance
characteristics relevant for program compilation while
still keeping a reference to the object carrying the
whole instance information, relevant for cost estimation.
TreeMap data structures are used as building blocks for
the complex search space structure to ensure ascending order
of the instance characteristics - memory and number of cores.
