Detailed Description

This class is used to redirect stdout and stderr outputs. It is never created directly; stdoutRedirect and stderrRedirect class methods should be use instead.

Note:

Redirection is done by replacing _write functions for stdout and stderr streams. Because of this messages written by NSLog(), for example are not redirected. I consider this a good thing, but if more universal redirecting is needed, it can be done at file descriptor level.

Member Function Documentation

- (void) addListener:

(id)

aListener

Adds specified object as listener for this output. Method stdoutRedirect: or stderrRedirect: of the listener is called to redirect the output.

- (void) forwardOutput:

(NSData *)

data

- (id) initWithStream:		(FILE *)	aStream
selector:		(SEL)	aSelector

- (void) removeListener:

(id)

aListener

Stops forwarding for this output to the specified listener object.

- (void) startRedirect

+ (id) stderrRedirect

Returns HBOutputRedirect object used to redirect stderr.

+ (id) stdoutRedirect

Returns HBOutputRedirect object used to redirect stdout.

- (void) stopRedirect
