AnyGene (Jenetics 3.8.0)

java.lang.Object
- org.jenetics.AnyGene<A>

All Implemented Interfaces:

Gene<A,AnyGene<A>>, Factory<AnyGene<A>>, Verifiable
```
public final class AnyGene<A>
extends Object
implements Gene<A,AnyGene<A>>
```
Gene implementation, which allows to create genes without explicit implementing the Gene interface.
class Main { // First monday of 2015. private static final LocalDate MIN_MONDAY = LocalDate.of(2015, 1, 5); // Supplier of random 'LocalDate' objects. The implementation is responsible // for guaranteeing the desired allele restriction. In this case we will // generate only mondays. static LocalDate nextRandomMonday() { return MIN_MONDAY.plusWeeks(RandomRegistry.getRandom().nextInt(1000)); } // Create a new 'LocalDate' gene. All other genes, created with // gene.newInstance(), are calling the 'newRandomMonday' method. final AnyGene<LocalDate> gene = AnyGene.of(Main::nextRandomMonday); }
The example above shows how to create LocalDate genes from a random LocalDate supplier. It also shows how to implement a restriction on the created dates. The usage of the AnyGene class is useful for supporting custom allele types without explicit implementation of the Gene interface. But the AnyGene can only be used for a subset of the existing alterers.

  - getAllele
```
public A getAllele()
```
    Description copied from interface: Gene
    
    Return the allele of this gene.
    
    Specified by:
    
    getAllele in interface Gene<A,AnyGene<A>>
    
    Returns:
    
    the allele of this gene.
  - newInstance
```
public AnyGene<A> newInstance()
```
    Description copied from interface: Gene
    
    Return a new, random gene with the same type and with the same constraints than this gene. For all genes returned by this method holds gene.getClass() == gene.newInstance().getClass(). Implementations of this method has to use the Random object which can be fetched from the RandomRegistry.
    
    Specified by:
    
    newInstance in interface Gene<A,AnyGene<A>>
    
    Specified by:
    
    newInstance in interface Factory<AnyGene<A>>
    
    Returns:
    
    a new instance of type T
  - newInstance
```
public AnyGene<A> newInstance(A value)
```
    Description copied from interface: Gene
    
    Create a new gene from the given value and the gene context.
    
    Specified by:
    
    newInstance in interface Gene<A,AnyGene<A>>
    
    Parameters:
    
    value - the value of the new gene.
    
    Returns:
    
    a new gene with the given value.
  - isValid
```
public boolean isValid()
```
    Description copied from interface: Verifiable
    
    Check if this object is valid.
    
    Specified by:
    
    isValid in interface Verifiable
    
    Returns:
    
    true if this object is valid, false otherwise.

```
    Create a new AnyGene instance with the given parameters. New (random) genes are created with the given allele supplier.
    
    Type Parameters:
    
    A - the allele type
    
    Parameters:
    
    allele - the actual allele instance the created gene represents. null values are allowed.
    
    supplier - the allele-supplier which is used for creating new, random alleles
    
    validator - the validator used for validating the created gene. This predicate is used in the isValid() method.
