ReceivedSharesIndexRDF

class ReceivedSharesIndexRDF : SolidRDFResource

RDF wrapper for {podRoot}/solidshare/shares/received_shares.ttl.

Symmetric to GivenSharesIndexRDF: each received share is a reified record node whose counterpart is the resource's owner, carrying the time the share was recorded:

<#share-…>
    rdf:type            solidshare:Share ;
    solidshare:resource <resourceUri> ;
    solidshare:owner    <ownerWebId> ;
    acl:mode            acl:Read ;
    dcterms:created     "2026-06-04T12:00:00Z"^^xsd:dateTime .

Legacy reads. Earlier versions stored a bare <ownerWebId> <acl:mode> <resourceUri> triple with no node and no time; getShares still surfaces those (with addedAt = null).

Constructors

ReceivedSharesIndexRDF

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

Types

Node

data class Node(val subject: String, val ownerWebId: String, val resourceUri: String, val mode: ShareMode, val addedAt: String?, val resourceType: String? = null, val resourceName: String? = null)

One reified solidshare:Share record. subject is the node IRI (the writer targets patch deletes at it); mode is the strongest acl:mode asserted; addedAt is the record's dcterms:created, or null. resourceType / resourceName are the record's solidshare:resourceType IRI and dcterms:title, both null on untyped (file/folder) records.

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.

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.

getLegacyFlatShares

fun getLegacyFlatShares(): List<ReceivedShare>

Shares stored in the legacy bare-triple form <ownerWebId> <acl:mode> <resourceUri> (no record node, addedAt = null).

getMetadata

open override fun getMetadata(): SolidMetadata

getShareNodes

fun getShareNodes(vocab: ShareVocabulary = SolidShareVocabulary): List<ReceivedSharesIndexRDF.Node>

The reified received-share records (node form only — excludes legacy flat rows).

getShares

fun getShares(vocab: ShareVocabulary = SolidShareVocabulary): List<ReceivedShare>

Every received share, one row per (ownerWebId, resourceUri) at the strongest mode: reified records first, then any legacy rows for pairs they don't cover, folded via collapseByOwner so an owner never appears more than once per resource.

getSize

fun getSize(): Long

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

writeToParcel

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