TicketsIndexRDF

class TicketsIndexRDF : SolidRDFResource

RDF representation of the tickets index document inside a tickets container — a solidshare:TicketIndex, the document the type index's solid:instance registration for schema:Ticket points at.

Mirrors the people-index idiom of the contacts data module: each ticket in the container gets one cached row keyed by its URI, so a wallet list can be rendered from a single GET without fetching every ticket document:

<> rdf:type solidshare:TicketIndex .

<…/{uuid}/ticket#this>
    rdf:type            schema:Ticket ;
    schema:name         "Concert" ;
    solidshare:category "EVENT" ;
    schema:startDate    "2026-07-14T19:30:00Z"^^xsd:dateTime ;
    solidshare:issuer   "Ticketmaster" ;
    schema:validThrough "2026-07-14T23:59:00Z"^^xsd:dateTime .

Writers must keep rows in step with the ticket documents (the tickets data module does this on every create/update/delete).

Constructors

TicketsIndexRDF

constructor(identifier: String, contentType: String? = null, quads: List<RdfQuad>? = null, headers: SolidHeaders? = null)

Functions

addQuad

fun addQuad(subject: String, predicate: String, obj: String, maxNumber: Int = 1)

Adds a triple whose object is an IRI (or blank node).

addQuadLiteral

fun addQuadLiteral(subject: String, predicate: String, value: String, datatype: String? = XSD.STRING, language: String? = null, maxNumber: Int = 1)

Adds a triple whose object is a literal.

addTicket

fun addTicket(ticket: TicketRDF)

Caches a row for ticket: its URI, title, category, event start, issuer display name, validity end, and pass colours (so a wallet list can paint each pass without fetching its document).

clearProperties

fun clearProperties(predicate: String, subject: String = itselfSubject)

Removes every triple with the given predicate for subject.

open override fun close()

describeContents

open override fun describeContents(): Int

ensureType

fun ensureType(subject: String, typeIri: String)

Ensures subject carries an rdf:type triple with typeIri, preserving any other type triples already present.

findAllProperties

fun findAllProperties(predicate: String): List<String>

Returns the object values of every triple with the given predicate, across all subjects.

findAllPropertiesForSubject

fun findAllPropertiesForSubject(subject: String, predicate: String): List<String>

Returns the object values of every triple matching the given subject and predicate.

findProperty

fun findProperty(predicate: String): String?

Returns the object value of the first triple with the given predicate, or null if none.

findPropertyForSubject

fun findPropertyForSubject(subject: String, predicate: String): String?

Returns the object value of the first triple matching subject and predicate, or null.

getAllQuads

fun getAllQuads(): List<RdfQuad>

Returns a snapshot copy of all triples held by this resource.

getContentType

open override fun getContentType(): String

The media type of the resource representation (the value of its Content-Type).

getCreatedTime

fun getCreatedTime(): Long?

The creation time in epoch milliseconds, from this resource's own dcterms:created (then stat:ctime) triple, or null when neither is present.

getEntity

open override fun getEntity(): InputStream

Returns the resource representation as a byte stream.

getHeaders

open override fun getHeaders(): SolidHeaders

The HTTP headers associated with this resource (empty when constructed locally).

getIdentifier

open override fun getIdentifier(): String

The URI that identifies this resource on the pod.

getLastModified

fun getLastModified(): Long?

The last-modified time in epoch milliseconds. Prefers this resource's own dcterms:modified (then stat:mtime) triple and falls back to the Last-Modified header. null when none is present.

getMetadata

open override fun getMetadata(): SolidMetadata

getSize

fun getSize(): Long

The size of this resource in bytes (its Content-Length), or 0 when the server did not report one.

getTickets

fun getTickets(): List<TicketSummary>

Returns every cached ticket row in this index. Rows missing a title are silently skipped.

removeTicket

fun removeTicket(ticketUri: String): Boolean

Removes all row triples for ticketUri.

updateTicket

fun updateTicket(ticket: TicketRDF): Boolean

Replaces the cached row for ticket (remove + re-add, so fields that became absent are dropped).

writeToParcel

open override fun writeToParcel(dest: Parcel, flags: Int)
