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.

Namespace:   System.Collections.Immutable
Assembly:  System.Collections.Immutable (in System.Collections.Immutable.dll)

public:
ImmutableSortedSet<T>::Builder^ ToBuilder()

Return Value

Type: System.Collections.Immutable::ImmutableSortedSet<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 ToBuildermethod, 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.
