All Known Implementing Classes:

Antlr4ParserPlugin

public interface ParserPlugin

A simple extension point to allow us to switch between the classic Groovy parser and the new Antlr based parser(s).

Method Summary

Modifier and Type	Method	Description
static ModuleNode	buildAST(CharSequence sourceText, CompilerConfiguration config, GroovyClassLoader loader, ErrorCollector errors)	Parses and converts the supplied source text into a module AST.
ModuleNode	buildAST(SourceUnit sourceUnit, ClassLoader classLoader, Reduction cst)	Builds the AST from a previously parsed CST.
Reduction	parseCST(SourceUnit sourceUnit, Reader reader)	Parses source text into a concrete syntax tree.

Method Details

parseCST

Reduction parseCST(SourceUnit sourceUnit,
 Reader reader)
            throws CompilationFailedException

Parses source text into a concrete syntax tree.

Parameters:

sourceUnit - the source being parsed

reader - the source reader

Returns:

the parsed CST

Throws:

CompilationFailedException - if parsing fails

buildAST

ModuleNode buildAST(SourceUnit sourceUnit,
 ClassLoader classLoader,
 Reduction cst)
             throws ParserException

Builds the AST from a previously parsed CST.

Parameters:

sourceUnit - the source being compiled

classLoader - the class loader to use during AST creation

cst - the parsed CST

Returns:

the resulting module node

Throws:

ParserException - if AST construction fails

buildAST

static ModuleNode buildAST(CharSequence sourceText,
 CompilerConfiguration config,
 GroovyClassLoader loader,
 ErrorCollector errors)
                    throws CompilationFailedException

Parses and converts the supplied source text into a module AST.

Parameters:

sourceText - the source text to compile

config - the compiler configuration to use

loader - the class loader used during compilation

errors - the collector that receives compilation errors

Returns:

the compiled module AST

Throws:

CompilationFailedException - if parsing or conversion fails
