Class ImmutableMultiPointArithmetic.Builder
java.lang.Object
net.bmahe.genetics4j.core.spec.combination.ImmutableMultiPointArithmetic.Builder
- Enclosing class:
ImmutableMultiPointArithmetic
Builds instances of type
ImmutableMultiPointArithmetic
.
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.

from
Fill a builder with attribute values from the providedMultiPointArithmetic
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
-
numCrossovers
Initializes the value for thenumCrossovers
attribute.- Parameters:
numCrossovers
- The value for numCrossovers- Returns:
this
builder for use in a chained invocation
-
alpha
Initializes the value for thealpha
attribute.If not set, this attribute will have a default value as returned by the initializer of
alpha
.- Parameters:
alpha
- The value for alpha- Returns:
this
builder for use in a chained invocation
-
build
Builds a newImmutableMultiPointArithmetic
.- Returns:
- An immutable instance of MultiPointArithmetic
- Throws:
