java.lang.Objectec.gp.GPType
ec.gp.GPSetType
A GPSetType is a GPType which contains GPAtomicTypes in a set, and is used as a generic GP type. For more information, see GPType GPSetTypes implement their set using both a hash table and an array. if the size of the set is "significantly big", then the hash table is used to look up membership in the set (O(1), but with a big constant). If the size is small, then the array is used (O(n)). The dividing line is determined by the constant START_USING_HASH_BEYOND, which you might play with to optimize for your system.

Constructor Summary | |
GPSetType()
You should not construct new types. |
Method Summary | |
boolean |
compatibleWith(GPType t)
Am I compatible with ("fit" with) t? For two atomic types, this is done by direct pointer equality. |
void |
postProcessSetType(int totalAtomicTypes)
Sets up the packed and sparse arrays based on the hashtable |
void |
setup(EvolutionState state,
Parameter base)
Sets up the object by reading it from the parameters stored in state, built off of the parameter base base. |
