abstract class NavType<T : Any!>

kotlin.Any
↳	androidx.navigation.NavType

Known Direct Subclasses

NavType.ParcelableArrayType, NavType.ParcelableType, NavType.SerializableArrayType, NavType.SerializableType

NavType.ParcelableArrayType	ParcelableArrayType is used for `NavArgument`s which hold arrays of Parcelables.
NavType.ParcelableType	ParcelableType is used for passing Parcelables in `NavArgument`s.
NavType.SerializableArrayType	SerializableArrayType is used for `NavArgument`s that hold arrays of Serializables.
NavType.SerializableType	SerializableType is used for Serializable `NavArgument`s.

Known Indirect Subclasses

NavType.EnumType

EnumType is used for NavArguments holding enum values.

NavType denotes the type that can be used in a NavArgument.

There are built-in NavTypes for primitive types, such as int, long, boolean, float, and strings, parcelable, and serializable classes (including Enums), as well as arrays of each supported type.

You should only use one of the static NavType instances and subclasses defined in this class.
