open override fun close()

describeContents

open override fun describeContents(): Int

enrichContained

fun enrichContained(refs: List<SolidSourceReference>)

Replaces the contained-resource references with refs.

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.

getContained

fun getContained(): List<SolidSourceReference>

Returns references to the resources directly contained in this container, parsed from its ldp:contains triples and any server-supplied stat metadata.

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.

getLabel

fun getLabel(): String?

Returns this container's rdfs:label, or null if it has none.

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

getOwner

fun getOwner(): String?

Returns the WebID of this storage's owner, or null if not advertised.

getSize

fun getSize(): Long

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