Interface TreeGene<A,G extends TreeGene<A,G>>

All Superinterfaces:

Factory<G>, FlatTree<A,G>, Gene<A,G>, Iterable<G>, Self<G>, Tree<A,G>, Verifiable

All Known Implementing Classes:

AbstractTreeGene, ProgramGene

public interface TreeGene<A,G extends TreeGene<A,G>>
extends Gene<A,G>, FlatTree<A,G>

Representation of tree shaped gene. Since the genes are part of a chromosome, they are implementing the FlatTree interface, which makes the required storage layout explicit.

Method Details

value

default A value()

Description copied from interface: Tree

Return the value of the current Tree node. The value may be null.

Specified by:

value in interface Tree<A,G extends TreeGene<A,G>>

Returns:

the value of the current Tree node

newInstance

G newInstance(A allele,
 int childOffset,
 int childCount)

Return a new tree gene with the given allele and the local tree structure.

Parameters:

allele - the actual gene allele

childOffset - the offset of the first node child within the chromosome

childCount - the number of children of the new tree gene

Returns:

a new tree gene with the given parameters

Throws:

IllegalArgumentException - if the childCount is smaller than zero

newInstance

default G newInstance(FlatTree<? extends A,?> tree)

Return a new tree gene from the given flat tree node.

Parameters:

tree - the flat tree node

Returns:

a new tree gene from the given flat tree node

Throws:

NullPointerException - if the given tree node is null
