fri.patterns.interpreter.parsergenerator.builder.SerializedParser
| SerializedParser | | public class SerializedParser extends SerializedObject (Code) | | This class is definitely the shortest way to construct a Parser (with Lexer) for a Syntax.
It uses all serialization utils in this package to quickly build a parsing environment.
This factory accepts a syntax where parser and lexer rules were mixed.
Example (syntax input from a file):
File ebnfFile = new File("MySyntax.syntax");
Parser parser = new SerializedParser().get(ebnfFile);
or (syntax input from a Reader, must pass a filename):
Reader ebnfReader = new InputStreamReader(MySyntaxSemantic.class.getResourceAsStream("MySyntax.syntax"));
Parser parser = new SerializedParser().get(ebnfReader, "MySyntax");

| Constructor Summary | |
| public | SerializedParser()
Create a Parser factory that caches built Lexers. | | public | SerializedParser(boolean production)
Create a Parser factory that caches built Lexers. |
| Method Summary | |
| public Parser | get(Object syntaxInput)
Builds the Parser from scratch if not found its parts in filesystem, else loads all serialized parts.
Parameters:
syntaxInput - the mixed lexer/parser syntax as File, InputStream, List of Lists, String [][] or Syntax. | | public Parser | get(Object syntaxInput, String baseName)
Builds the Parser from scratch if not found its parts in filesystem, else loads all serialized parts. | | public Parser | get(Class parserType, Object syntaxInput)
Builds the Parser from scratch if not found its parts in filesystem, else loads all serialized parts.
Parameters:
parserType - the class of ParserTables to create for the syntax (LALRParserTables.class is default).
Parameters:
syntaxInput - the mixed lexer/parser syntax as File, InputStream, List of Lists, String [][] or Syntax. | | public Parser | get(Class parserType, Object syntaxInput, String baseName)
Builds the parsing environment from scratch if not found its parts in filesystem, else loads all serialized parts. | | public static void | main(String[] args)
Test main. | | protected SerializedLexer | newSerializedLexer()
To be overridden when a modified SerializedLexer is needed. |
| PARSERFILE_SUFFIX | | final public static String PARSERFILE_SUFFIX(Code) | | The suffix for serialized Parser files.
|
| PRODUCTION | | protected boolean PRODUCTION(Code) | | |
| SerializedParser | | public SerializedParser()(Code) | | Create a Parser factory that caches built Lexers.
|
| SerializedParser | | public SerializedParser(boolean production)(Code) | | Create a Parser factory that caches built Lexers. @param production when false the Parser will not be serialized.
|
| get | | public Parser get(Object syntaxInput) throws Exception(Code) | | Builds the Parser from scratch if not found its parts in filesystem, else loads all serialized parts.
Parameters:
syntaxInput - the mixed lexer/parser syntax as File, InputStream, List of Lists, String [][] or Syntax. Parser, built from scratch or loaded from filesystem. |
| get | | public Parser get(Object syntaxInput, String baseName) throws Exception(Code) | | Builds the Parser from scratch if not found its parts in filesystem, else loads all serialized parts.
Parameters:
syntaxInput - the mixed lexer/parser syntax as File, InputStream, List of Lists, String [][] or Syntax.
Parameters:
baseName - basename for serialization, can be null Parser, built from scratch or loaded from filesystem. |
| get | | public Parser get(Class parserType, Object syntaxInput) throws Exception(Code) | | Builds the Parser from scratch if not found its parts in filesystem, else loads all serialized parts.
Parameters:
parserType - the class of ParserTables to create for the syntax (LALRParserTables.class is default).
Parameters:
syntaxInput - the mixed lexer/parser syntax as File, InputStream, List of Lists, String [][] or Syntax. Parser, built from scratch or loaded from filesystem. |
| get | | public Parser get(Class parserType, Object syntaxInput, String baseName) throws Exception(Code) | | Builds the parsing environment from scratch if not found its parts in filesystem, else loads all serialized parts.
Parameters:
parserType - the class of ParserTables to create for the syntax (LALRParserTables.class is default).
Parameters:
syntaxInput - the mixed lexer/parser syntax as File, InputStream, List of Lists, String [][] or Syntax.
Parameters:
baseName - basename for serialization, can be null Parser, built from scratch or loaded from filesystem. |
| main | | public static void main(String[] args)(Code) | | Test main. Building serialized Java Parser takes 740, building from scratch takes 4000 millis.
