AbstractGssParser (closure-stylesheets 1.6.3 API)

java.lang.Object
- com.google.common.css.compiler.ast.AbstractGssParser

Direct Known Subclasses:

GssParser
```
public abstract class AbstractGssParser
extends java.lang.Object
```
Base parser implementation that delegates management of the underlying JavaCC parser to the subclass. This class does not expose any public methods; subclasses should expose an appropriate interface.

protected final AbstractGssParser.ParseResult parseInternal(java.util.List<SourceCode> sources,
                                                            boolean errorHandling)
                                                     throws GssParserException
```
    Parses a list of GSS sources. Subclasses should use this method to do the actual parsing of SourceCode objects. It will in turn call the subclass's implementation of getParser() as necessary.
    
    Parameters:
    
    sources - a list of GSS SourceCode objects to parse
    
    errorHandling - if error handling should be enabled. If this is false, no GssParserExceptions will be returned in the result.
    
    Returns:
    
    ParseResult the result containing the CssTree and parsing errors
    
    Throws:
    
    GssParserException
  - getParser
```
protected abstract GssParserCC getParser()
```
    Implementations must return an empty GssParserCC object. Whether this object is actually new or not isn't important which allows pooling.
