Syntax

public class RegexpTreeNode<TElement, TElementSet>
    where TElementSet : CanCreatePartialUniform<TElementSet>, IImmutableDistribution<TElement, TElementSet>, new()

Type Parameters

Name	Description
TElement	The type of a character in a language word.
TElementSet	The type of a sequence element set.

Remarks

Although this class might look immutable, Microsoft.ML.Probabilistic.Distributions.Automata.RegexpTreeNode`2.Simplify(System.Boolean) can change the tree rooted at the node by removing existing children and/or adding new.
