Applies given transformations to a value

Properties

$transformations

Stores list of registered transformations

private static array<string, string> $transformations = ['add' => \acdhOeaw\arche\lib\disserv\dissemination\transformation\AddParam::class, 'base64' => \acdhOeaw\arche\lib\disserv\dissemination\transformation\Base64Encode::class, 'part' => \acdhOeaw\arche\lib\disserv\dissemination\transformation\UriPart::class, 'set' => \acdhOeaw\arche\lib\disserv\dissemination\transformation\SetParam::class, 'substr' => \acdhOeaw\arche\lib\disserv\dissemination\transformation\Substr::class, 'url' => \acdhOeaw\arche\lib\disserv\dissemination\transformation\UrlEncode::class, 'rawurlencode' => \acdhOeaw\arche\lib\disserv\dissemination\transformation\RawUrlEncode::class, 'removeprotocol' => \acdhOeaw\arche\lib\disserv\dissemination\transformation\RemoveProtocol::class]

Methods

__construct()

Creates an object representing a repository resource.

public __construct(string $urlOrId, RepoInterface $repo) : mixed
Parameters
$urlOrId : string

either a resource URL or just the numeric id

$repo : RepoInterface

repository connection object

applyTransformations()

Applies given transformations to a value

public static applyTransformations(string $value[, array<string|int, string> $transformations = [] ]) : string
Parameters
$value : string

value

$transformations : array<string|int, string> = []

transformations to be applied to the value

Return values
string

getClasses()

Returns all RDF types (classes) of a given repository resource.

public getClasses() : array<string|int, string>
Return values
array<string|int, string>

getDissServices()

Returns list of dissemination services available for a resource.

public getDissServices() : array<string, Service>
Return values
array<string, Service>

getGraph()

Returns resource metadata.

public getGraph() : DatasetNodeInterface

Fetches them from the repository with the loadMetadata() if they were not fetched already.

A reference to the metadata is returned meaning adjusting the returned object automatically affects the resource metadata.

getIds()

Returns an array with all repository resource identifiers.

public getIds() : array<string|int, string>
Return values
array<string|int, string>

getMetadata()

Returns resource metadata.

public getMetadata() : DatasetNodeInterface

Fetches them from the repository with the loadMetadata() if they were not fetched already.

A deep copy of metadata is returned meaning adjusting the returned object does not automatically affect the resource metadata. Use the setMetadata() method to write back the changes you made.

getMetadataStatement()

Returns a QueryPart object with an SQL query loading resource's metadata in a given mode.

public getMetadataStatement([string $mode = self::META_RESOURCE ][, string|null $parentProperty = null ][, array<string|int, string> $resourceProperties = [] ][, array<string|int, string> $relativesProperties = [] ]) : PDOStatement
Parameters
$mode : string = self::META_RESOURCE

scope of the metadata returned by the repository - see the RepoDb()::getPdoStatementBySqlQuery() method

$parentProperty : string|null = null

RDF property name used to find related resources

$resourceProperties : array<string|int, string> = []

list of RDF properties to be includes for a resource (if the list is empty, all exsiting RDF properties are included)

$relativesProperties : array<string|int, string> = []

list of RDF properties to be includes for resources being relatives (if the list is empty, all exsiting RDF properties are included)

Return values
PDOStatement

getName()

Returns parameter name

public getName() : string
Return values
string

getUri()

Returns the repository resource URL.

public getUri() : TermInterface
Return values
TermInterface

getValue()

Return parameter value for a given repository resource

public getValue(RepoResourceInterface $res[, array<string|int, string> $transformations = [] ][, string|null $prefix = null ][, bool $forcePrefix = false ]) : string
Parameters
$res : RepoResourceInterface

repository resource to get the value for

$transformations : array<string|int, string> = []

transformations to be applied to the value

$prefix : string|null = null

preferred value prefix

$forcePrefix : bool = false

should error be thrown if $prefix is defined and no value with a given prefix can be found

transform()
Return values
string

isA()

Naivly checks if the resource is of a given class.

public isA(string $class) : bool

Naivly means that a given rdfs:type triple must exist in the resource metadata.

Parameters
$class : string
Return values
bool

setGraph()

Replaces resource metadata with a given RDF graph. A reference to the provided metadata is stored meaning future modifications of the $metadata object automatically affect the resource metadata.

public setGraph(DatasetInterface $metadata) : void

New metadata are not automatically written back to the repository. Use the updateMetadata() method to write them back.

Parameters
$metadata : DatasetInterface

setMetadata()

Replaces resource metadata with a given RDF resource graph. A deep copy of the provided metadata is stored meaning future modifications of the $metadata object don't affect the resource metadata.

public setMetadata(DatasetNodeInterface $metadata) : void

New metadata is not automatically written back to the repository. Use the updateMetadata() method to write them back.

Parameters
$metadata : DatasetNodeInterface

findValue()

private findValue(DatasetNodeInterface $meta, string|null $prefix, bool $force) : string
Parameters

$prefix : string|null
$force : bool
Return values
string

getServiceClass()

private abstract getServiceClass() : string
