Enum DummyType

java.lang.Object

java.lang.Enum<DummyType>

net.hydromatic.morel.type.DummyType

All Implemented Interfaces:

Serializable, Comparable<DummyType>, Type

public enum DummyType
extends Enum<DummyType>
implements Type

Type that is a place-holder for a type constructor that has no arguments; for example, "NONE" in "datatype 'a option = NONE | SOME of 'a" would have dummy type.

Method Detail

values

public static DummyType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DummyType c : DummyType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DummyType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

key

public Type.Key key()

Description copied from interface: Type

Description of the type, e.g. "int", "int -> int", "NONE | SOME of 'a".

Specified by:

copy

public DummyType copy(TypeSystem typeSystem,
                      UnaryOperator<Type> transform)

Description copied from interface: Type

Copies this type, applying a given transform to component types, and returning the original type if the component types are unchanged.

Specified by:

copy in interface Type
