 java.lang.ClassLoader
org.codehaus.janino.JavaSourceClassLoader
All known Subclasses: org.codehaus.janino.CachingJavaSourceClassLoader,
| JavaSourceClassLoader | | public class JavaSourceClassLoader extends ClassLoader (Code) | | A
ClassLoader that, unlike usual
ClassLoader s,
does not load byte code, but reads JavaTM source code and then scans, parses,
compiles and loads it into the virtual machine.
As with any
ClassLoader , it is not possible to "update" classes after they've been
loaded. The way to achieve this is to give up on the
JavaSourceClassLoader and create
a new one.

| Inner Class :public interface ProtectionDomainFactory | |
| Method Summary | |
| protected Class | defineBytecode(String className, byte[] ba)
Calls
java.lang.ClassLoader.defineClass(java.lang.Stringbyte[]intint) or
java.lang.ClassLoader.defineClass(java.lang.Stringbyte[]intintjava.security.ProtectionDomain) ,
depending on whether or not a
ProtectionDomainFactory was set. | | protected Class | defineBytecodes(String name, Map bytecodes)
Define a set of classes, like
java.lang.ClassLoader.defineClass(java.lang.Stringbyte[]intint) . | | protected Class | findClass(String name)
Implementation of
ClassLoader.findClass(String) . | | protected Map | generateBytecodes(String name)
Find, scan, parse the right compilation unit. | | public static void | main(String[] args)
Read JavaTM source code for a given class name, scan, parse, compile and load
it into the virtual machine, and invoke its "main()" method with the given args.
Usage is as follows:
java [ java-option ] org.codehaus.janino.JavaSourceClassLoader [ option ] ... | | public void | setCompileErrorHandler(UnitCompiler.ErrorHandler optionalCompileErrorHandler)
| | public void | setProtectionDomainFactory(ProtectionDomainFactory protectionDomainFactory)
| | public void | setWarningHandler(WarningHandler optionalWarningHandler)
|
| JavaSourceClassLoader | | public JavaSourceClassLoader(ClassLoader parentClassLoader, File[] optionalSourcePath, String optionalCharacterEncoding, EnumeratorSet debuggingInformation)(Code) | | Set up a
JavaSourceClassLoader that finds JavaTM source code in a file
that resides in either of the directories specified by the given source path.
You can specify to include certain debugging information in the generated class files, which
is useful if you want to debug through the generated classes (see
Scanner.Scanner(StringReader) ).
Parameters:
parentClassLoader - See ClassLoader
Parameters:
optionalSourcePath - A collection of directories that are searched for JavaTM source files in the given order
Parameters:
optionalCharacterEncoding - The encoding of the JavaTM source files (null for platform default encoding)
Parameters:
debuggingInformation - What kind of debugging information to generate, see DebuggingInformation |
| JavaSourceClassLoader | | public JavaSourceClassLoader(ClassLoader parentClassLoader, ResourceFinder sourceFinder, String optionalCharacterEncoding, EnumeratorSet debuggingInformation)(Code) | | Set up a
JavaSourceClassLoader that finds JavaTM source code through
a given
ResourceFinder .
You can specify to include certain debugging information in the generated class files, which
is useful if you want to debug through the generated classes (see
Scanner.Scanner(StringReader) ).
Parameters:
parentClassLoader - See ClassLoader
Parameters:
sourceFinder - Used to locate additional source files
Parameters:
optionalCharacterEncoding - The encoding of the JavaTM source files (null for platform default encoding)
Parameters:
debuggingInformation - What kind of debugging information to generate, see DebuggingInformation |
| generateBytecodes | | protected Map generateBytecodes(String name) throws ClassNotFoundException(Code) | | Find, scan, parse the right compilation unit. Compile the parsed compilation unit to
bytecode. This may cause more compilation units being scanned and parsed. Continue until
all compilation units are compiled.
String name => byte[] bytecode, or null if no source code could be found
throws:
ClassNotFoundException - on compilation problems |
| main | | public static void main(String[] args)(Code) | | Read JavaTM source code for a given class name, scan, parse, compile and load
it into the virtual machine, and invoke its "main()" method with the given args.
Usage is as follows:
java [ java-option ] org.codehaus.janino.JavaSourceClassLoader [ option ] ... class-name [ arg ] ...
java-option Any valid option for the Java Virtual Machine (e.g. "-classpath colon-separated-list-of-class-directories")
option:
-sourcepath colon-separated-list-of-source-directories
-encoding character-encoding
-g Generate all debugging info");
-g:none Generate no debugging info");
-g:{lines,vars,source} Generate only some debugging info");
-cache dir Cache compiled classes here");
