Application.clearStreams()

Availability

Flash Communication Server MX 1.0.

Usage

application.clearStreams(streamPath)

Parameters

streamPath A string that indicates the URI of a stream.

Returns

A Boolean value of true if the stream at the specified path was deleted; otherwise, false. If using wildcard characters to clear multiple stream files, the method returns true only if all the streams matching the wildcard pattern were successfully deleted; otherwise it returns false.

Description

Method; clears recorded streams (FLV) files and MP3 files associated with the application instance. You can use this method to clear a single stream, all streams associated with the application instance, just those streams in a specific subdirectory of the application instance, or just those streams whose names match a specified wildcard pattern.

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.

Example

The following example clears all recorded streams:

function onApplicationStop(){
    application.clearStreams("/");
}

The following example clears all MP3 files from the application instance's /disco subdirectory:

function onApplicationStop(){
    application.clearStreams("mp3:/disco/*");
}
