Class DocumentServiceClient (0.45.0)

GitHub RepositoryProduct Reference

Service Description: This service lets you manage document.

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()) {
   LocationName parent = LocationName.of("[PROJECT]", "[LOCATION]");
   Document document = Document.newBuilder().build();
   CreateDocumentResponse response = documentServiceClient.createDocument(parent, document);
 }

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

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(LocationName parent, Document document)

  • createDocument(String parent, Document document)

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

  • createDocumentCallable()

GetDocument

Gets a document. Returns NOT_FOUND if the document does not exist.

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)

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);

policy com.google.iam.v1.Policy

Required. REQUIRED: The complete policy to be applied to the resource. The size of the policy is limited to a few 10s of KB. This refers to an Identity and Access (IAM) policy, which specifies access controls for the Document.

You can set ACL with condition for projects only.

Supported operators are: =, !=, <, <=, >, and >= where the left of the operator is DocumentSchemaId or property name and the right of the operator is a number or a quoted string. You must escape backslash (\) and quote (") characters.

Boolean expressions (AND/OR) are supported up to 3 levels of nesting (for example, "((A AND B AND C) OR D) AND E"), a maximum of 10 comparisons are allowed in the expression. The expression must be < 6000 bytes in length.

Sample condition: "DocumentSchemaId = "some schema id" OR SchemaId.floatPropertyName >= 10"
