Product Reference

Service Description: Service for ingesting Document information of the customer's website.

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 (DocumentServiceClient documentServiceClient = DocumentServiceClient.create()) {
   DocumentName name =
       DocumentName.ofProjectLocationDataStoreBranchDocumentName(
           "[PROJECT]", "[LOCATION]", "[DATA_STORE]", "[BRANCH]", "[DOCUMENT]");
   Document response = documentServiceClient.getDocument(name);
 }
 

Note: close() needs to be called on the DocumentServiceClient 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
GetDocument	Gets a Document.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getDocument(GetDocumentRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. getDocument(DocumentName name) getDocument(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getDocumentCallable()
ListDocuments	Gets a list of Documents.	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(BranchName 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. listDocumentsPagedCallable() listDocumentsCallable()
CreateDocument	Creates a Document.	Request object method variants only take one parameter, a request object, which must be constructed before the call. createDocument(CreateDocumentRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. createDocument(BranchName parent, Document document, String documentId) createDocument(String parent, Document document, String documentId) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. createDocumentCallable()
UpdateDocument	Updates a Document.	Request object method variants only take one parameter, a request object, which must be constructed before the call. updateDocument(UpdateDocumentRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. updateDocumentCallable()
DeleteDocument	Deletes a Document.	Request object method variants only take one parameter, a request object, which must be constructed before the call. deleteDocument(DeleteDocumentRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. deleteDocument(DocumentName name) deleteDocument(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. deleteDocumentCallable()
ImportDocuments	Bulk import of multiple Documents. Request processing may be synchronous. Non-existing items will be created. Note: It is possible for a subset of the Documents to be successfully updated.	Request object method variants only take one parameter, a request object, which must be constructed before the call. importDocumentsAsync(ImportDocumentsRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. importDocumentsOperationCallable() importDocumentsCallable()
PurgeDocuments	Permanently deletes all selected Documents in a branch. This process is asynchronous. Depending on the number of Documents to be deleted, this operation can take hours to complete. Before the delete operation completes, some Documents might still be returned by DocumentService.GetDocument or DocumentService.ListDocuments. To get a list of the Documents to be deleted, set PurgeDocumentsRequest.force to false.	Request object method variants only take one parameter, a request object, which must be constructed before the call. purgeDocumentsAsync(PurgeDocumentsRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. purgeDocumentsOperationCallable() purgeDocumentsCallable()

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 DocumentServiceSettings 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
 DocumentServiceSettings documentServiceSettings =
     DocumentServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 DocumentServiceClient documentServiceClient =
     DocumentServiceClient.create(documentServiceSettings);
 

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
 DocumentServiceSettings documentServiceSettings =
     DocumentServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 DocumentServiceClient documentServiceClient =
     DocumentServiceClient.create(documentServiceSettings);
 

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
 DocumentServiceSettings documentServiceSettings =
     DocumentServiceSettings.newHttpJsonBuilder().build();
 DocumentServiceClient documentServiceClient =
     DocumentServiceClient.create(documentServiceSettings);
