Constructor Detail

ParserCompiler

public ParserCompiler(Class<?> superClass)
               throws IOException,

Creates a parser using annotations in parserClass.

Parameters:

superClass -

fullyQualifiedname -

Throws:

NoSuchMethodException

IOException

NoSuchFieldException

ClassNotFoundException

ReflectiveOperationException

ParserCompiler

public ParserCompiler(Class<?> superClass,
              Grammar grammar)
               throws IOException,
                      ReflectiveOperationException

Creates a parser using grammar.

Parameters:

superClass - Super class for parser. Possible parser annotations are not processed.

grammar - The grammar

Throws:

NoSuchMethodException

IOException

NoSuchFieldException

ReflectiveOperationException

Method Detail

compile

public void compile()
             throws IOException,
                    ReflectiveOperationException

Description copied from interface: ClassCompiler

Compile classfile

Specified by:

compile in interface ClassCompiler

Throws:

IOException

ReflectiveOperationException

getLrkLevel

public int getLrkLevel()

saveClass

public void saveClass()
               throws IOException

Saves Parser class in java classfile format in dir. File path is defined by dir and classname. Example dir = c:\temp class is foo.bar.Main file path is c:\temp\foo\bar\Main.class if srcDir is not null, creates a byte code source file to dir. File content is similar to the output of javap utility. Your IDE might be able to use this file for debugging the actual byte code. (NetBeans can if this file located like java source files) Example dir = c:\src class is foo.bar.Main Source file path is c:\src\foo\bar\Main.jasm

Specified by:

saveClass in interface ClassCompiler

Throws:

IOException

createSource

public void createSource(File dir)
                  throws IOException

Creates a byte code source file to dir. File content is similar to the output of javap utility. Your IDE might be able to use this file for debugging the actual byte code. (NetBeans can if this file located like java source files) Example dir = c:\src class is foo.bar.Main Source file path is c:\src\foo\bar\Main.jasm

Parameters:

dir -

Throws:

IOException

loadDynamic

public Class<?> loadDynamic()

Compile the parser class dynamically. Nice method for experimenting and testing. For real parser use ant task ParserBuilder

Returns:

Throws:

IOException

InstantiationException

IllegalAccessException

public Object parserInstance()

setDebug

public void setDebug(boolean debug)

Deprecated.

Parameters:

debug -

setSrcDir

public void setSrcDir(File srcDir)

Description copied from interface: ClassCompiler

Set the directory for source files and documents

Specified by:

setSrcDir in interface ClassCompiler
