Class JavaCompileCommand
java.lang.Object
com.sun.javatest.Command
com.sun.javatest.lib.JavaCompileCommand
public class JavaCompileCommand
- extends Command
Invoke a Java compiler via reflection.
The compiler is assumed to have a constructor and compile method
matching the following signature:
public class COMPILER {
public COMPILER(java.io.OutputStream out, String compilerName);
public boolean compile(String[] args);
}
or
public class COMPILER {
public COMPILER();
public int compile(String[] args);
}
or
public class COMPILER {
public static int compile(String[] args, PrintWriter out);
}
This means the command is suitable for (but not limited to) the
compiler javac suplied with JDK. (Note that this uses an internal
API of javac which is not documented and is not guaranteed to exist
in any specific release of JDK.)

JavaCompileCommand
public JavaCompileCommand()
main
public static void main(java.lang.String[] args)
- A stand-alone entry point for this command. An instance of this
command is created, and its
run
method invoked,
passing in the command line args and System.out
and
System.err
as the two streams.
- Parameters:
args
- command line arguments for this command.- See Also:
run(java.lang.String[], java.io.PrintWriter, java.io.PrintWriter)
run
public Status run(java.lang.String[] args,
java.io.PrintWriter log,
java.io.PrintWriter ref)
- Invoke a specified compiler, or the default, javac.
If the first word in the
args
array is "-compiler"
the second is interpreted as the class name for the compiler to be
invoked, optionally preceded by a name for the compiler, separated
from the class name by a colon. If no -compiler is specified,
the default is `javac:com.sun.tools.javac.Main'. If -compiler is specified
but no compiler name is given before the class name, the default name
will be `java ' followed by the classname. For example, `-compiler Main'
will result in the class name being `Main' and the compiler name being
`java Main'. After determining the class and compiler name,
an instance of the compiler class will be created, passing it a stream
using the ref
parameter, and the name of the compiler.
Then the `compile' method will be invoked, passing it the remaining
values of the `args' parameter. If the compile method returns true,
the result will be a status of `passed'; if it returns `false', the
result will be `failed'. If any problems arise, the result will be
a status of `error'.
- Specified by:
run
in class Command
- Parameters:
args
- An optional specification for the compiler to be invoked,
followed by arguments for the compiler's compile method.log
- Not used.ref
- Passed to the compiler that is invoked.
- Returns:
- `passed' if the compilation is successful; `failed' if the
compiler is invoked and errors are found in the file(s)
being compiler; or `error' if some more serious problem arose
that prevented the compiler performing its task.
