C# Class Antlr4.Runtime.ListTokenSource

Provides an implementation of ITokenSource as a wrapper around a list of IToken objects.

If the final token in the list is an TokenConstants.EOF token, it will be used as the EOF token for every call to NextToken() after the end of the list is reached. Otherwise, an EOF token will be created.
