public interface NativeHeaderTool extends Tool, OptionChecker {
Creates a future for a native header task with the given
components and arguments. The task might not have
completed as described in the NativeHeaderTask interface.
If a file manager is provided, it must be able to handle all locations defined in StandardLocation.
Params: - out – a Writer for additional output from the task; use
System.err if null - fileManager – a file manager; if
null use the task's standard filemanager - diagnosticListener – a diagnostic listener; if
null use the compiler's default method for reporting diagnostics - options – task options,
null means no options - classes – class names for which native headers should be generated
Throws: - RuntimeException – if an unrecoverable error occurred in a user supplied component. The cause will be the error in user code.
- IllegalArgumentException – if any of the given compilation units are of other kind than source
Returns: an object representing the task to be done

Returns a new instance of the standard file manager implementation
for this tool. The file manager will use the given diagnostic
listener for producing any non-fatal diagnostics. Fatal errors
will be signalled with the appropriate exceptions.
The standard file manager will be automatically reopened if it is accessed after calls to flush or close. The standard file manager must be usable with other tools.
Params: - diagnosticListener – a diagnostic listener for non-fatal diagnostics; if
null use the tool's default method for reporting diagnostics - locale – the locale to apply when formatting diagnostics;
null means the default locale. - charset – the character set used for decoding bytes; if
null use the platform default
Returns: the standard file manager
