Class ImmutableProportionalTournament.Builder<T extends Comparable<T>>

java.lang.Object

net.bmahe.genetics4j.core.spec.selection.ImmutableProportionalTournament.Builder<T>

Enclosing class:

ImmutableProportionalTournament<T extends Comparable<T>>

public static final class ImmutableProportionalTournament.Builder<T extends Comparable<T>>
extends Object

Builds instances of type ProportionalTournament. 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.

Method Details

from

public final ImmutableProportionalTournament.Builder<T> from(ProportionalTournament<T> instance)

Fill a builder with attribute values from the provided ProportionalTournament instance. Regular attribute values will be replaced with those from the given instance. Absent optional values will not replace present values.

Parameters:

instance - The instance from which to copy values

Returns:

this builder for use in a chained invocation

numCandidates

public final ImmutableProportionalTournament.Builder<T> numCandidates(int numCandidates)

Initializes the value for the numCandidates attribute.

Parameters:

numCandidates - The value for numCandidates

Returns:

this builder for use in a chained invocation

proportionFirst

public final ImmutableProportionalTournament.Builder<T> proportionFirst(double proportionFirst)

Initializes the value for the proportionFirst attribute.

Parameters:

proportionFirst - The value for proportionFirst

Returns:

this builder for use in a chained invocation

firstComparator

public final ImmutableProportionalTournament.Builder<T> firstComparator(Comparator<Individual<T>> firstComparator)

Initializes the value for the firstComparator attribute.

Parameters:

firstComparator - The value for firstComparator

Returns:

this builder for use in a chained invocation

secondComparator

public final ImmutableProportionalTournament.Builder<T> secondComparator(Comparator<Individual<T>> secondComparator)

Initializes the value for the secondComparator attribute.

Parameters:

secondComparator - The value for secondComparator

Returns:

this builder for use in a chained invocation

build

public ProportionalTournament<T> build()

Builds a new ProportionalTournament.

Returns:

An immutable instance of ProportionalTournament

Throws:

IllegalStateException - if any required attributes are missing

formatRequiredAttributesMessage

private String formatRequiredAttributesMessage()
