RES_STATE_ACTIVE

public mixed RES_STATE_ACTIVE = 'active'

Properties

$resourceClass

A class used to instantiate objects representing repository resources.

public static string $resourceClass = \acdhOeaw\arche\lib\RepoResourceDb::class

To be used by external libraries extending the RepoResource class funcionality provided by this library.

$baseUrl

Repository REST API base URL

private string $baseUrl

$headers

An object providing mappings of repository REST API parameters to HTTP headers used by a given repository instance.

private object $headers

$nonRelationProperties

private array<string|int, string> $nonRelationProperties

$queryLog

private AbstractLogger|null $queryLog

$schema

An object providing mappings of repository concepts to RDF properties used to denote them by a given repository instance.

private Schema $schema

Methods

__construct()

public __construct(string $baseUrl, Schema $schema, Schema $headers, PDO $pdo[, array<string|int, string> $nonRelationProperties = [] ][, AuthInterface $auth = null ]) : mixed
Parameters
$baseUrl : string
$schema : Schema
$headers : Schema
$pdo : PDO
$nonRelationProperties : array<string|int, string> = []
$auth : AuthInterface = null

factory()

Creates a repository object instance from a given configuration file.

public static factory(string $configFile[, string $dbSettings = 'guest' ]) : RepoDb

Automatically parses required config properties and passes them to the RepoDb object constructor.

At the moment it doesn't support authorization provider instantiating.

Parameters
$configFile : string

a path to the YAML config file

$dbSettings : string = 'guest'

database connection variant to read from the config

Return values
RepoDb

getBaseUrl()

Returns the repository REST API base URL.

public getBaseUrl() : string
Return values
string

getGraphBySearchTerms()

Returns RDF metadata graph of the search results.

public getGraphBySearchTerms(array<string|int, SearchTerm> $searchTerms, SearchConfig $config) : Dataset
Parameters
$searchTerms : array<string|int, SearchTerm>
$config : SearchConfig
Return values
Dataset

getGraphBySqlQuery()

Returns RDF metadata graph of the search results.

Parameters
$query : string
$parameters : array<string|int, mixed>
$config : SearchConfig
Return values
Dataset

getHeaderName()

Returns an HTTP header name to be used to pass a given information in the repository request.

public getHeaderName(string $purpose) : string
Parameters
$purpose : string
Return values
string

getMetadataAuthQuery()

public getMetadataAuthQuery() : QueryPart

getResourceByIds()

Tries to find a single repository resource matching provided identifiers.

public getResourceByIds(array<string|int, string> $ids[, SearchConfig|null $config = null ]) : RepoResourceDb

A resource matches the search if at lest one id matches the provided list. Resource is not required to have all provided ids.

If more then one resources matches the search or there is no resource matching the search, an error is thrown.

Parameters
$ids : array<string|int, string>

an array of identifiers (being strings)

$config : SearchConfig|null = null
