Enclosing class:

ImmutableProgramTreeChromosomeSpec

public static final class ImmutableProgramTreeChromosomeSpec.Builder
extends Object

Builds instances of type ImmutableProgramTreeChromosomeSpec. 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.

Parameters:

instance - The instance from which to copy values

Returns:

this builder for use in a chained invocation

program

public final ImmutableProgramTreeChromosomeSpec.Builder program(Program program)

Initializes the value for the program attribute.

Parameters:

program - The value for program

Returns:

this builder for use in a chained invocation

build

public ImmutableProgramTreeChromosomeSpec build()

Builds a new ImmutableProgramTreeChromosomeSpec.

Returns:

An immutable instance of ProgramTreeChromosomeSpec

Throws:

IllegalStateException - if any required attributes are missing
