Method Detail

getContainer

public static Optional<IRI> getContainer(IRI identifier)

Get the structural-logical container for this resource.

Parameters:

identifier - the resource identifier

Returns:

a container, if one exists. Only the root resource would return empty here.

normalizeIdentifier

For any identifier, normalize its form to remove any hashURIs or trailing slashes.

Parameters:

identifier - the identifier

Returns:

a normalized identifier

buildTrellisIdentifier

public static IRI buildTrellisIdentifier(String path)

Build a Trellis identifier from a path string.

Parameters:

path - the resource path

Returns:

the trellis identifier

normalizePath

public static String normalizePath(String path)

Normalize a path component for a Trellis identifier.

Parameters:

path - the path

Returns:

the normalized path

toGraph

public static Collector<Triple,?,Graph> toGraph()

Collect a stream of Triples into a Graph.

Returns:

a graph

toDataset

public static org.trellisldp.api.TrellisUtils.DatasetCollector toDataset()

Collect a stream of Quads into a Dataset.

Returns:

a Collector that accumulates a Stream of Quads into a Dataset
