Parser (The Adobe Experience Manager SDK 2022.11.9850.20221116T162329Z-220900)

java.lang.Object
- org.mozilla.javascript.Parser

Direct Known Subclasses:

IRFactory
```
public class Parser
extends java.lang.Object
```
This class implements the JavaScript parser.
It is based on the SpiderMonkey C source files jsparse.c and jsparse.h in the jsref package.
The parser generates an AstRoot parse tree representing the source code. No tree rewriting is permitted at this stage, so that the parse tree is a faithful representation of the source for frontend processing tools and IDEs.
This parser implementation is not intended to be reused after a parse finishes, and will throw an IllegalStateException() if invoked again.

public AstRoot parse(java.lang.String sourceString,
                     java.lang.String sourceURI,
                     int lineno)
```
    Builds a parse tree from the given source string.
    
    Returns:
    
    an AstRoot object representing the parsed program. If the parse fails, null will be returned. (The parse failure will result in a call to the ErrorReporter from CompilerEnvirons.)

    Throws:
    
    java.io.IOException - if the Reader encounters an error
