DocumentManagerImpl

class DocumentManagerImpl(val identifier: String, val storage: Storage, val secureAreaRepository: SecureAreaRepository, val ktorHttpClientFactory: () -> HttpClient? = null) : DocumentManager

Default implementation of the DocumentManager interface for the EUDI Wallet.

This implementation provides the core functionality for managing digital documents in the EUDI Wallet ecosystem, including:

• Creation of documents with multiple supported formats (MSO mDoc, SD-JWT VC)
• Secure storage and retrieval of documents using provided storage mechanisms
• Management of document lifecycle and state transitions
• Integration with secure area for cryptographic operations and key management

The implementation maintains strict document identity boundaries by using a unique document manager identifier to ensure that documents managed by one instance cannot be accessed or modified by another instance.

Parameters

release

identifier	Unique identifier for this document manager instance
storage	Storage implementation for persisting document data
secureAreaRepository	Repository for secure key management and cryptographic operations
ktorHttpClientFactory	Optional factory method to create HTTP clients

Constructors

DocumentManagerImpl	[release] constructor(identifier: String, storage: Storage, secureAreaRepository: SecureAreaRepository, ktorHttpClientFactory: () -> HttpClient? = null) Creates a new DocumentManagerImpl with the required dependencies

Types

Name	Summary
Companion	[release] object Companion

Properties

Name	Summary
identifier	[release] open override val identifier: String Unique identifier for this document manager instance, used to scope document access
ktorHttpClientFactory	[release] val ktorHttpClientFactory: () -> HttpClient? Optional factory to provide custom HTTP clients for network operations
secureAreaRepository	[release] open override val secureAreaRepository: SecureAreaRepository Repository for cryptographic operations and secure key management
storage	[release] open override val storage: Storage Persistent storage implementation for document data

Functions

Name	Summary
createDocument	[release] open override fun createDocument(format: DocumentFormat, createSettings: CreateDocumentSettings, issuerMetadata: IssuerMetadata? = null): Outcome<UnsignedDocument> Create a new document. This method will create a new document with the given format and keys settings. If the document is successfully created, it will return an UnsignedDocument. This UnsignedDocument contains the keys and the method to proof the ownership of the keys, that can be used with an issuer to retrieve the document's claims. After that the document can be stored using storeIssuedDocument or storeDeferredDocument.
deleteDocumentById	[release] open override fun deleteDocumentById(documentId: DocumentId): Outcome<ProofOfDeletion?> Delete a document by its identifier.
getDocumentById	[release] open override fun getDocumentById(documentId: DocumentId): Document? Retrieve a document by its identifier.
getDocuments	[release] open override fun getDocuments(predicate: (Document) -> Boolean? = null): List<Document> Retrieve all documents.
getDocuments	[release] inline fun <T : Document> DocumentManager.getDocuments(): List<T> DocumentManager Extension function that returns a list of documents of type T. If T is IssuedDocument, then only IssuedDocument will be returned. If T is UnsignedDocument, then only UnsignedDocument will be returned, excluding DeferredDocument. If T is DeferredDocument, then only DeferredDocument will be returned.
storeDeferredDocument	[release] open override fun storeDeferredDocument(unsignedDocument: UnsignedDocument, relatedData: ByteArray): Outcome<DeferredDocument> Store an unsigned document for deferred issuance. This method will store the document with the related to the issuance data.
storeIssuedDocument	[release] open override fun storeIssuedDocument(unsignedDocument: UnsignedDocument, issuerProvidedData: List<IssuerProvidedCredential>): Outcome<IssuedDocument> Store an issued document. This method will store the document with its issuer provided data.
