BackedEnum pseudointerface manual page: The BackedEnum interface
|
Note that this (pseudo)interface cannot actually be implemented as a standard class; it can only be (pseudo)implemented by declaring a backed enum.
Definition
interface BackedEnum extends UnitEnum {
static from(int|string $value): static;
static tryFrom(int|string $value): ?static;
string|int $value; // pseudocode
// Inherited from UnitEnum:
static UnitEnum::cases(): array;
static cases(): array;
string $name; // pseudocode
}
The member-variables are labelled "pseudocode" because a normal interface can't declare member-variables.
