Class Nutrient

java.lang.Object
com.codename1.health.nutrition.Nutrient
public final class Nutrient extends Object

A single nutrient that a NutritionSample can carry -- a macronutrient, a vitamin, a mineral.

Interned constants, like HealthDataType, so == is a valid identity test and forId(String) stays total across framework versions.

Each nutrient declares the unit its amounts are expressed in. That is not cosmetic: sodium is conventionally logged in milligrams and protein in grams, and a food database that mixes them up is off by a thousand.

  • Field Details

    • ENERGY

      public static final Nutrient ENERGY
      Food energy. Note that this is also available as a standalone type, HealthDataType.DIETARY_ENERGY; writing a NutritionSample that carries it makes it part of a logged meal rather than a bare total.

    • values

      public static List<Nutrient> values()
      Every nutrient this framework understands.

    • toString

      public String toString()
      Description copied from class: Object
      Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method. The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: getClass().getName() + '@' + Integer.toHexString(hashCode())
      Overrides:
