ImmutableSortedSet<T>.ToBuilder Method

Definition

Namespace:

System.Collections.Immutable

Assembly:

System.Collections.Immutable.dll

Source:

ImmutableSortedSet_1.cs

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

public:
 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

Returns

ImmutableSortedSet<T>.Builder

The sorted set builder.

Remarks

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.
