本文整理了Java中com.google.javascript.jscomp.Compiler.hasErrors()方法的一些代码示例，展示了Compiler.hasErrors()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Compiler.hasErrors()方法的具体详情如下：
包路径：com.google.javascript.jscomp.Compiler
类名称：Compiler
方法名：hasErrors

Compiler.hasErrors介绍

[英]Consults the ErrorManager to see if we've encountered errors that should halt compilation.

If CompilerOptions#ideMode is true, this function always returns false without consulting the error manager. The error manager will continue to be told about new errors and warnings, but the compiler will complete compilation of all inputs.
[中]咨询ErrorManager，查看是否遇到了应停止编译的错误。
如果CompilerOptions#ideMode为true，则此函数始终返回false，而无需咨询错误管理器。错误管理器将继续被告知新的错误和警告，但编译器将完成所有输入的编译。

代码示例

 * Instrument code for coverage.

 * <p>{@code parseForCompilation()} must be called before this method is called.
 *
 * <p>The caller is responsible for also calling {@code generateReport()} to generate a report of
 * warnings and errors to stderr. See the invocation in {@link #compile} for a good example.
 *
 * <p>This method is mutually exclusive with stage1Passes() and stage2Passes().
 * Either call those two methods or this one, but not both.
