    ValueType represents the type that users will work with.

    ValueType represents the type that users will work with. For OptionalTypedField, this is equal to Option[ThisType].

  4. abstract def setFromAny(in: Any): Box[MyType]

    Set the value of the field from anything.

    Set the value of the field from anything. Implementations of this method should accept at least the following (pattern => valueBox)

    • value: MyType => setBox(Full(value))
    • Some(value: MyType) => setBox(Full(value))
    • Full(value: MyType) => setBox(Full(value))
    • (value: MyType)::_ => setBox(Full(value))
    • s: String => setFromString(s)
    • Some(s: String) => setFromString(s)
    • Full(s: String) => setFromString(s)
    • null|None|Empty => setBox(defaultValueBox)
    • f: Failure => setBox(f) And usually convert the input to a string and uses setFromString as a last resort.

    Note that setFromAny should _always_ call setBox, even if the conversion fails. This is so that validation properly notes the error.

    The method genericSetFromAny implements this guideline.

  5. abstract def setFromJValue(jvalue: JValue): Box[MyType]

    Decode the JValue and set the field to the decoded value.

    Decode the JValue and set the field to the decoded value. Returns Empty or Failure if the value could not be set

    Definition Classes
    TypedField
  6. abstract def setFromString(s: String): Box[MyType]

    Set the value of the field using some kind of type-specific conversion from a String.

    Set the value of the field using some kind of type-specific conversion from a String. By convention, if the field is optional_?, then the empty string should be treated as no-value (Empty). Note that setFromString should _always_ call setBox, even if the conversion fails. This is so that validation properly notes the error.

    returns

    Full(convertedValue) if the conversion succeeds (the field value will be set by side-effect) Empty or Failure if the conversion does not succeed
