abstract const class sys::Enum
sys::Obj sys::Enum
Enum is the base class for enum classes defined using the enum keyword. An enum models a fixed range of discrete values. Each value has an Int ordinal and a Str name.
Every enum class implicitly has the following slots auto-generated by the compiler:
- a static const field for each name in the enum's range.
- a static field called "vals" which contains the list of discrete values indexed by ordinal.
- a static method called "fromStr" which maps an enum name to an enum instance
See Enums for details.
- compare
-
virtual override Int compare(Obj obj)Compare based on ordinal value.
- doFromStr
-
protected const static Enum? doFromStr(Type t, Str name, Bool checked)Protected fromStr implementation - for compiler use only. A public static fromStr method is always auto-generated by the compiler for each enum.
- equals
-
virtual override Bool equals(Obj? obj)Enums are only equal if same instance using ===.
- make
-
new make(Int ordinal, Str name)Protected constructor - for compiler use only.
- name
-
Str name()Get the programatic name for this enum.
- ordinal
-
Int ordinal()Return ordinal value which is a zero based index into values.
- toStr
-
virtual override Str toStr()Always returns name().
