Compiler (Closure Compiler v20190929 API)

java.lang.Object
- com.google.javascript.jscomp.AbstractCompiler
- - com.google.javascript.jscomp.Compiler

All Implemented Interfaces:

CompilerInputProvider, ErrorHandler, SourceExcerptProvider, SourceFileMapping
```
public class Compiler
extends AbstractCompiler
implements ErrorHandler, SourceFileMapping
```
Compiler (and the other classes in this package) does the following:
- parses JS code
- checks for undefined variables
- performs optimizations such as constant folding and constants inlining
- renames variables (to short names)
- outputs compact JavaScript code
External variables are declared in 'externs' files. For instance, the file may include definitions for global javascript/browser objects such as window, document.

```
    Performs all the bookkeeping required at the end of a compilation.

    DO call it even when hasErrors() returns true.
  - instrumentForCoverage
```
