Class LevelHolder

java.lang.Object
  org.encog.ml.prg.opp.LevelHolder

public class LevelHolder
extends Object

The level holder class is passed down as a tree is mutated. The level holder class is initially given the desired output of the program and tracks the desired output for each of the nodes. This allows for type-safe crossovers and mutations.

Constructor Summary

LevelHolder(int currentLevel)
Construct the level holder.

Method Summary

static boolean	compatibleTypes(List<ValueType> parentTypes, List<ValueType> childTypes) Determine if the specified child types are compatible with the parent types.
void	decreaseLevel() Decrease the level.
int	getCurrentLevel()
ProgramNode	getNodeFound()
List<ValueType>	getTypes()
void	setCurrentLevel(int currentLevel)
void	setNodeFound(ProgramNode nodeFound)
void	setTypes(List<ValueType> types)
