Preferences.Key<Boolean>	the Preferences.Key for name

doubleKey

const fun doubleKey(name: String!): Preferences.Key<Double>

Get a key for a Double preference. You should not have multiple keys with the same name (for use with the same Preferences). Using overlapping keys with different types can result in ClassCastException.

Parameters
name: String!	the name of the preference

Returns
Preferences.Key<Double>	the Preferences.Key for name

floatKey

const fun floatKey(name: String!): Preferences.Key<Float>

Get a key for a Float preference. You should not have multiple keys with the same name (for use with the same Preferences). Using overlapping keys with different types can result in ClassCastException.

intKey

const fun intKey(name: String!): Preferences.Key<Int>
