DataSetCmd

This macro implements an interface to send a command to the DataSet application (the STx Workspace). It can only be used whilst the DataSet application is running.

Before a DATASETCMD function is called, the Workspace object ($BSTXINI) and the DataSet object ($BDATASET) must be unlocked (detached) if they were locked (attached) by the calling application. If one of these objects is locked, a deadlock situation may occur.

General Usage

DATASETCMD subcommand [ args ]

subcommand

The command to be sent to the DataSet application.

args

The command specific arguments (see below).

The DATASETCMD does not return a result. The following subcommands are implemented.

GETSELECTED

Retrieve a list of selected segments or parameters from the Workspace Detail. Note that this command can only be called from the BScript environment (i.e. a script).

Usage:

#list := DATASETCMD GETSELECTED SEGMENTS

Result:

A table where each entry has the following format:

audioSetIref ; audioSegmentId ; audioChannelAttributeValue

Usage:

#list := DATASETCMD GETSELECTED PARAMETERS

Result:

A table where each entry has the following format:

audioSetIref ; audioSegmentId ; indexOfAnalysedChannel ; parameterMethodName ; parameterType

Usage:

#list := DATASETCMD GETSELECTED SETS

Result:

A table where each entry has one of the following formats, depending on the set type (AFile, ASequence, ASegList or Set):

AFile ; elementId ; elementIref ; samplingRate ; numberOfChannels ; fullFilePath

ASequence ; elementId ; elementIref ; samplingRate ; numberOfChannels

ASegList ; elementId ; elementIref

Set ; elementId ; elementIref



SETSELECTED

Selects an audio-set element in the Overview (by IREF) and select segments in the Detail (by ID). Note that this command currently only works for AFile and ASegList audio sets.

Usage:

DATASETCMD SETSELECTED iref ; segList

Parameters:

iref

The IREF to an audio set element.

segList

A semi-colon separated list of segment IDs in the element referenced by iref.

Shows a dialog to select a script file in the Script Controller.

Usage:

DATASETCMD SELECTSCRIPT [ defaultFile ]

Result:

An empty string.



NEWDATASET

Opens a dialog to create a new (empty) DataSet file.

Usage:

DATASETCMD NEWDATASET [ fileName ]

Parameters:

fileName

The file name to use for the new DataSet. If no file name is specified, the user is asked to specify one.

Result:

An empty string if successful, or an error code on failure.
