Overview

This category on DRTrack defines methods that make setting and retrieving the various DRTrack properties easier.

Methods

-length

Returns the length of the track data.

-preGap

Returns the length of the pre gap.

-setPreGap:

Sets the length of the pre gap.

Returns the length of the track data.

- (DRMSF*) length; 

Return Value

A DRMSF representing the length of the track.

Discussion

The length returned does not include the length of the pregap. Only the length of the track data itself is returned.

Returns the length of the pre gap.

- (DRMSF*) preGap; 

Return Value

A DRMSF representing the length of the pre gap.

Discussion

This is a simple wrapper to obtain the DRPreGapLengthKey . If the DRPreGapLengthKey property has not been set for the track this method will return a zero-length DRMSF object (0m:0s:0f).

Sets the length of the pre gap.

- (void) setPreGap:(DRMSF*)preGap; 

Parameters

Discussion

This is a simple wrapper to set the DRPreGapLengthKey.
