Class JavacTask

java.lang.Object
  wcs.Task
      wcs.ProcessTask
          wcs.JavacTask

All Implemented Interfaces:

Runnable

public class JavacTask
extends ProcessTask

task to run the Java compiler. BUG: this should not use ProcessTask. BUG: this does not support all conceivable options.

Nested Class Summary

Nested classes/interfaces inherited from class wcs.Task

Task.Exception, Task.In, Task.Out

Field Summary

protected ArrayList	args commandline.
String	className set by each call to addToSources(wcs.Task.In).
protected StringBuffer	classpath classpath.
String	packagePath set by each call to addToSources(wcs.Task.In).
protected static Pattern	packagePattern pattern to extract package path, if any, and public class name.
protected File	src root of source file area.

argv

Fields inherited from class wcs.Task

env, err, in, out

Constructor Summary

JavacTask(File tmpDir, Task.Out err, Properties env) required property: javac Java compiler Optional properties: javac.bootclasspath javac.extdirs

intended for crosscompilation, e.g., version 1.3 for MSIE javac.deprecation true for Java compiler -deprecation option javac.source Java compiler -source value

Method Summary

void	addToClasspath(File component) add a component to the classpath.
void	addToSources(String packagePath, String className, Task.In in) add a source file: move the content to the workarea.
void	addToSources(Task.In in) add a source file.
static void	main(String[] argv) test: run commandline with system properties, keep workarea.
void	run() insert args as ProcessTask.argv and insert classpath, delegate to base method.

Field Detail

packagePattern

protected static final Pattern packagePattern

pattern to extract package path, if any, and public class name. BUG: this will fail if a dotted path contains whitespace or comments.

classpath

protected final StringBuffer classpath

classpath.

src

protected final File src

root of source file area.

args

protected final ArrayList args

commandline.

packagePath

public String packagePath

set by each call to addToSources(wcs.Task.In).

className

public String className

set by each call to addToSources(wcs.Task.In).

Constructor Detail

JavacTask

public JavacTask(File tmpDir,
                 Task.Out err,
                 Properties env)
          throws IOException

required property:

javac

Java compiler

Optional properties:

javac.bootclasspath javac.extdirs	intended for crosscompilation, e.g., version 1.3 for MSIE
javac.deprecation	true for Java compiler -deprecation option
javac.source	Java compiler -source value

Parameters:

tmpDir - root of workarea; src will contain source files, classes will contain class files.

Throws:

IOException

Method Detail

addToClasspath

public void addToClasspath(File component)
                    throws IOException

add a component to the classpath.

Throws:

IOException

addToSources

public void addToSources(Task.In in)
                  throws IOException

add a source file. Does not allow java.lang as a package path or prefix, does not allow System as a classname, silently overwrites duplicate files. Sets packagePath and className.

Throws:

IOException

addToSources

public void addToSources(String packagePath,
                         String className,
                         Task.In in)
                  throws IOException

add a source file: move the content to the workarea.

Throws:

IOException

run

public void run()
         throws Task.Exception

insert args as ProcessTask.argv and insert classpath, delegate to base method.

Specified by:

run in interface Runnable

Overrides:

run in class ProcessTask

Throws:

Task.Exception

main

public static void main(String[] argv)
                 throws Exception

test: run commandline with system properties, keep workarea.

Throws:

Exception
