22 Server-Side ActionScript Language Reference
The streamPath parameter specifies the location and name of a stream, relative to the
application’s instance directory. You can include a slash (/) as a delimiter between directories
in the path. The last element in the path can contain wildcard patterns (for example, a
question mark [?] and an asterisk [*]) or a stream name. The
application.clearStreams()
method traverses the stream hierarchy along the specified path and clears all the recorded
streams that match the given wildcard pattern. Specifying a slash clears all the streams
associated with an application instance.
To clear MP3 files associated with the application instance, precede the path to the stream
with
mp3: (for example, mp3:/streamPath). By default, the application.clearStreams()
method clears only recorded FLV streams. You can also explicitly clear only FLV streams by
placing
flv: before the stream path (for example, flv:/streamPath). See the following
Example section for examples of clearing FLV and MP3 files.
The following examples show some possible values for the
streamPath parameter:
■ / or flv:/ clears all recorded (FLV) streams associated with the instance.
■ /report clears the stream file report.flv from the application instance directory.
■ /presentations/intro clears the recorded stream file intro.flv from the application
instance’s /presentations subdirectory; if
intro is a directory name, no streams are deleted.
■ /presentations/* clears all recorded stream files stored from the application instance’s /
presentations subdirectory. The /presentation
subdirectory is also deleted if no streams are
used in this namespace.
■ mp3:/ clears all MP3 files associated with the instance.
■ mp3:/mozart/requiem clears the MP3 file named requiem.mp3 from the application
instance’s /mozart subdirectory.
■ mp3:/mozart/* clears all MP3 file from the application instance’s /mozart subdirectory.
■ /presentations/report?? clears all recorded (FLV) streams that begin with “report”,
followed by any two characters. If there are directories within the given directory listing,
the directories are cleared of any streams that match
report??.
If an
application.clearStreams() method is invoked on a stream that is currently
recording, the recorded file is set to length 0 (cleared), and the internal cached data is also
cleared.
NOTE
You can also use the Server Management ActionScript API removeApp method to delete
all the resources for a single instance.
