Grammar.getTokenName介绍

[英]Gets the name by which a token can be referenced in the generated code. For tokens defined in a tokens{}} block or via a lexer rule, this is the declared name of the token. For token types generated by the use of a string literal within a parser rule of a combined grammar, this is the automatically generated token type which includes the #AUTO_GENERATED_TOKEN_NAME_PREFIX prefix. For types which are not associated with a defined token, this method returns #INVALID_TOKEN_NAME.
[中]获取可在生成的代码中引用标记的名称。对于在tokens{}块中或通过lexer规则定义的令牌，这是已声明的令牌名称。对于通过在组合语法的解析器规则中使用字符串文字生成的令牌类型，这是自动生成的令牌类型，其中包括#AUTO_generated_token_NAME_前缀。对于未与定义的令牌关联的类型，此方法返回#INVALID_token_NAME。
