GPInitializer (ecj 26 API)

java.lang.Object
- ec.Initializer
- - ec.simple.SimpleInitializer
  - - ec.gp.GPInitializer

All Implemented Interfaces:

Setup, Singleton, Serializable
```
public class GPInitializer
extends SimpleInitializer
```
GPInitializer is a SimpleInitializer which sets up all the Cliques, ( the initial [tree/node]constraints, types, and function sets) for the GP system.
Note that the Cliques must be set up in a very particular order:
1. GPType
2. GPNodeConstraints
3. GPFunctionSets
4. GPTreeConstraints
Parameter bases

gp.type GPTypes

gp.nc GPNodeConstraints

gp.tc GPTreeConstraints

gp.fs GPFunctionSets

public void setup(EvolutionState state,

```
    Description copied from interface: Setup
    
    Sets up the object by reading it from the parameters stored in state, built off of the parameter base base. If an ancestor implements this method, be sure to call super.setup(state,base); before you do anything else.
    
    Specified by:
    
    setup in interface Setup
    
    Overrides:
    
    setup in class SimpleInitializer
  - setupTypes
```
public void setupTypes(EvolutionState state,
                       Parameter base)
```
    Sets up all the types, loading them from the parameter file. This must be called before anything is called which refers to a type by name.
  - postProcessTypes
```
public void postProcessTypes()
```
    Assigns unique integers to each atomic type, and sets up compatibility arrays for set types. If you add new types (heaven forbid), you should call this method again to get all the types set up properly. However, you will have to set up the function sets again as well, as their arrays are based on these type numbers.
  - setupNodeConstraints
```
public void setupNodeConstraints(EvolutionState state,
                                 Parameter base)
```
    Sets up all the GPNodeConstraints, loading them from the parameter file. This must be called before anything is called which refers to a type by name.
  - setupFunctionSets
```
public void setupFunctionSets(EvolutionState state,
                              Parameter base)
```
  - setupTreeConstraints
```
public void setupTreeConstraints(EvolutionState state,
                                 Parameter base)
```
    Sets up all the GPTreeConstraints, loading them from the parameter file. This must be called before anything is called which refers to a type by name.
