value
to the set. -

elements
to this set. -

Checks whether any element of this iterable satisfies
test
.inherited -
asNameMap(

Available on Iterable<
Creates a map from the names of enum values to the values.T> , provided by the EnumByName extension -
byName(
String name) → T -
Available on Iterable<
Finds the enum value in this list with nameT> , provided by the EnumByName extensionname
. -
cast<
T> () → Set< T> -

R
instances.inherited -
clear(
