Class Track

  • Direct Known Subclasses:
    AudioTrack, SubtitleTrack, VideoTrack

    public abstract class Track
extends Object
    A class representing a track contained in a media resource. A media resource may have multiple parallel tracks, such as a video track with several audio tracks in different languages. The types of tracks supported by the system may be inferred from the existing subclasses of this class. Not all media resources will contain a track of each supported type, and the time span of a given track need not be commensurate with the time span of the containing media.
    Since:
    JavaFX 2.0

    • Method Detail

      • getName

        public final String getName​()
        Retrieves the name of the track.
        Returns:
        the track name or null.

      • getLocale

        public final Locale getLocale​()
        The Locale specifying the language and possibly the country that the Track contents are formatted for. For AudioTracks this will be the language spoken, for SubtitleTracks this will be the language presented in the captions. Not all Tracks will have an associated language, in which case this method will return null.
        Returns:
        the Tracks language information or null
        Since:
        JavaFX 8.0

      • getTrackID

        public final long getTrackID​()
        Get the track ID as defined by the media container format. The ID of each Track must be unique for its source Media.
        Returns:
        the Tracks unique ID
        Since:
        JavaFX 8.0

      • getMetadata

        public final Map<String,Object> getMetadata​()
        Returns:
        a Map containing all known metadata for this Track
        Since:
        JavaFX 8.0

      • toString

        public final String toString​()
        Description copied from class: Object
        Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

        The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: 

         getClass().getName() + '@' + Integer.toHexString(hashCode())
        Overrides:
        toString in class Object
        Returns:
        a string representation of the object.
