Class DocumentsClient (4.55.0)

GitHub RepositoryProduct Reference

Service Description: Service for managing knowledge Documents.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (DocumentsClient documentsClient = DocumentsClient.create()) {
   DocumentName name =
       DocumentName.ofProjectKnowledgeBaseDocumentName(
           "[PROJECT]", "[KNOWLEDGE_BASE]", "[DOCUMENT]");
   Document response = documentsClient.getDocument(name);
 }

Note: close() needs to be called on the DocumentsClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method Description Method Variants

ListDocuments

Returns the list of all documents of the knowledge base.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • listDocuments(ListDocumentsRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • listDocuments(KnowledgeBaseName parent)

  • listDocuments(String parent)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of DocumentsSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 DocumentsSettings documentsSettings =
     DocumentsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 DocumentsClient documentsClient = DocumentsClient.create(documentsSettings);

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 DocumentsSettings documentsSettings =
     DocumentsSettings.newBuilder().setEndpoint(myEndpoint).build();
 DocumentsClient documentsClient = DocumentsClient.create(documentsSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 DocumentsSettings documentsSettings = DocumentsSettings.newHttpJsonBuilder().build();
 DocumentsClient documentsClient = DocumentsClient.create(documentsSettings);

Reloads the specified document from its specified source, content_uri or content. The previously loaded content of the document will be deleted. Note: Even when the content of the document has not changed, there still may be side effects because of internal implementation changes.

This method is a long-running operation. The returned Operation type has the following method-specific fields:

- metadata: KnowledgeOperationMetadata - response: Document

Note: The projects.agent.knowledgeBases.documents resource is deprecated; only use projects.knowledgeBases.documents.
