public class DocumentsClient implements BackgroundResource

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:

 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().

The surface of this class includes several types of Java methods for each of the API's methods:

1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

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:

 DocumentsSettings documentsSettings =
     DocumentsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 DocumentsClient documentsClient = DocumentsClient.create(documentsSettings);
 

To customize the endpoint:

 DocumentsSettings documentsSettings =
     DocumentsSettings.newBuilder().setEndpoint(myEndpoint).build();
 DocumentsClient documentsClient = DocumentsClient.create(documentsSettings);

reloadDocumentAsync(DocumentName name, GcsSource gcsSource)

public final OperationFuture<Document,KnowledgeOperationMetadata> reloadDocumentAsync(DocumentName name, GcsSource gcsSource)

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. Note: If the document source is Google Cloud Storage URI, its metadata will be replaced with the custom metadata from Google Cloud Storage if the import_gcs_custom_metadata field is set to true in the request.

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.

Sample code:

 try (DocumentsClient documentsClient = DocumentsClient.create()) {
   DocumentName name =
       DocumentName.ofProjectKnowledgeBaseDocumentName(
           "[PROJECT]", "[KNOWLEDGE_BASE]", "[DOCUMENT]");
   GcsSource gcsSource = GcsSource.newBuilder().build();
   Document response = documentsClient.reloadDocumentAsync(name, gcsSource).get();
 }
 

Parameters

Name	Description
name	DocumentName Required. The name of the document to reload. Format: projects/<Project ID>/locations/<Location ID>/knowledgeBases/<Knowledge Base ID>/documents/<Document ID>
gcsSource	GcsSource The path for a Cloud Storage source file for reloading document content. If not provided, the Document's existing source will be reloaded.

Returns
