Kind

@Js
const abstract class Kind : Obj

Kind provides a type signature for a Haystack data value

 constructors fromStr

Parse a signature to its Kind representation

 fields name

Name of kind

 type

Fantom type for the kind

 methods toStr

Return signature

 fromType

Lookup Kind for a Fantom type

 fromVal

Lookup Kind for a Fantom object

 fromDefName

Lookup Kind from its lower case def name

 equals

Equality is based signature

 hash

Hash is based signature

 equals virtual Bool equals(Obj? that)

Equality is based signature

 fromDefName static Kind? fromDefName(Str name, Bool checked)

Lookup Kind from its lower case def name

 fromStr static new fromStr(Str signature, Bool checked)

Parse a signature to its Kind representation. If it cannot be parsed to a known kind, then return null or raise an exception.

 fromType static Kind? fromType(Type? type, Bool checked)

Lookup Kind for a Fantom type

 fromVal static Kind? fromVal(Obj? val, Bool checked)

Lookup Kind for a Fantom object

 hash virtual Int hash()

Hash is based signature

 name const Str : name

Name of kind: Bool, Number, List, etc

 toStr virtual Str toStr()
