C# 클래스 Antlr4.Runtime.CommonTokenStream

This class extends BufferedTokenStream with functionality to filter token streams to tokens on a particular channel (tokens where IToken.Channel() returns a particular value).

This token stream provides access to all tokens by index or when calling methods like BufferedTokenStream.GetText() . The channel filtering is only used for code accessing tokens via the lookahead methods BufferedTokenStream.La(int) , Lt(int) , and Lb(int) .

By default, tokens are placed on the default channel ( TokenConstants.DefaultChannel ), but may be reassigned by using the ->channel(HIDDEN) lexer command, or by using an embedded action to call Lexer.Channel .

Note: lexer rules which use the ->skip lexer command or call Lexer.Skip() do not produce tokens at all, so input text matched by such a rule will not be available as part of the token stream, regardless of channel.

channel 보호되어 있는 프로퍼티

Specifies the channel to use for filtering tokens.

The default value is TokenConstants.DefaultChannel , which matches the default channel assigned to tokens created by the lexer.
