Class ImmutableDoubleChromosomeSpec.Builder
java.lang.Object
net.bmahe.genetics4j.core.spec.chromosome.ImmutableDoubleChromosomeSpec.Builder
- Direct Known Subclasses:
DoubleChromosomeSpec.Builder
- Enclosing class:
ImmutableDoubleChromosomeSpec
Builds instances of type
ImmutableDoubleChromosomeSpec
.
Initialize attributes and then invoke the build()
method to create an
immutable instance.
Builder
is not thread-safe and generally should not be stored in a field or collection,
but instead used immediately to create instances.
