Overview
The Album data class represents a music album in Deeztracker Mobile. It contains metadata about an album including its title, artist, cover art, and a collection of tracks.
Album Model
Defined in app/src/main/java/com/crowstar/deeztrackermobile/data/model/Album.kt
Properties
Unique identifier for the album
Artist name for the album
Optional URL to the album’s cover art image. Can be null if no cover is available.
tracks
List<Track>
default:"emptyList()"
List of tracks contained in the album. Defaults to an empty list if no tracks are provided.
Relationship to Tracks
The Album model has a one-to-many relationship with Track objects. Each album can contain multiple tracks through the tracks property, which is a List<Track>.
val album = Album(
id = "album123",
title = "A Night at the Opera",
artist = "Queen",
coverUrl = "https://example.com/covers/album123.jpg",
tracks = listOf(
Track(
id = "track1",
title = "Bohemian Rhapsody",
artist = "Queen",
album = "A Night at the Opera",
duration = 354000L,
coverUrl = "https://example.com/covers/album123.jpg",
streamUrl = "https://example.com/stream/track1"
),
// More tracks...
)
)
