PHP/native/UnitEnum

Note that this (pseudo)Template:L/php cannot actually be implemented as a standard Template:L/php; it can only be (pseudo)implemented by declaring an Template:L/php.

If an enum is "backed" (declared as having a scalar value for each choice), it will implement this interface but also the Template:L/same interface.)

Definition

interface UnitEnum {
  static function cases(): array

  string $name; // pseudocode
}

The member-variable is labelled "pseudocode" because a normal interface can't declare member-variables.

cases()

This method returns an array containing one element for each case in the enum:

• Template:Fmt/arg (int) => Template:Fmt/arg (BackedEnum)

This list can then be used to build other arrays indexing the enum class's names and/or any other information known to each case.
