code: @Nonnull
  	public static LLogicalOperator logicalOperatorFrom(Consumer<LLogicalOperatorBuilder> buildingFunction) {
  		LLogicalOperatorBuilder builder = new LLogicalOperatorBuilder();
  		buildingFunction.accept(builder);
  		return builder.build();
  	}
docs: One of ways of creating builder. This is possibly the least verbose way where compiler should be able to guess the generic parameters.
