从以下内容开始将消耗最少的资源:

The minimal resources would be consumed by starting with the following:

parser.removeErrorListeners();
parser.setErrorStrategy(new BailErrorStrategy());
try {
    parser.ruleName();
    System.out.println("The sentence was contained in the grammar.");
} catch (ParseCancellationException) {
    System.out.println("The sentence was not contained in the grammar.");
}

然后将其更新为也可以使用ANTLR 4本书中介绍的两阶段解析策略.

And then updating this to also use the two-stage parsing strategy descibed in the ANTLR 4 book.
