ImmutableSortedSet<T>.ToBuilder Method


Creates a collection that has the same contents as this immutable sorted set that can be efficiently manipulated by using standard mutable interfaces.

 System::Collections::Immutable::ImmutableSortedSet<T>::Builder ^ ToBuilder();
public System.Collections.Immutable.ImmutableSortedSet<T>.Builder ToBuilder ();
member this.ToBuilder : unit -> System.Collections.Immutable.ImmutableSortedSet<'T>.Builder
Public Function ToBuilder () As ImmutableSortedSet(Of T).Builder



The sorted set builder.


If you need to perform multiple operations on an immutable collection, to increase efficiency you can copy the ImmutableSortedSet<T> to a ImmutableSortedSet<T>.Builder, using the ToBuilder method, manipulate the set and make it immutable again using the ToImmutable method. This will not change the original immutable sorted set.

This is an O(1) operation and results in only a single (small) memory allocation. The mutable collection that is returned is not thread safe.
