// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
 * Service Description: This service lets you manage document-links. Document-Links are treated as
 * sub-resources under source 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:
 *
 * 
{@code
 * // 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 (DocumentLinkServiceClient documentLinkServiceClient = DocumentLinkServiceClient.create()) {
 *   DocumentName parent =
 *       DocumentName.ofProjectLocationDocumentName("[PROJECT]", "[LOCATION]", "[DOCUMENT]");
 *   ListLinkedTargetsResponse response = documentLinkServiceClient.listLinkedTargets(parent);
 * }
 * }
 *
 * 
Note: close() needs to be called on the DocumentLinkServiceClient 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
 ListLinkedTargets
 Return all target document-links from the document.

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

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

 *           
 listLinkedTargets(DocumentName parent)
 *           
 listLinkedTargets(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.
 *      

 *           
 listLinkedTargetsCallable()
 *      
 *       
 ListLinkedSources
 Return all source document-links from the document.

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

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

 *           
 listLinkedSources(DocumentName parent)
 *           
 listLinkedSources(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.
 *      

 *           
 listLinkedSourcesPagedCallable()
 *           
 listLinkedSourcesCallable()
 *      
 *       
 CreateDocumentLink
 Create a link between a source document and a target document.

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

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

 *           
 createDocumentLink(DocumentName parent, DocumentLink documentLink)
 *           
 createDocumentLink(String parent, DocumentLink documentLink)
 *      
 *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
 *      

 *           
 createDocumentLinkCallable()
 *      
 *       
 DeleteDocumentLink
 Remove the link between the source and target documents.

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

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

 *           
 deleteDocumentLink(DocumentLinkName name)
 *           
 deleteDocumentLink(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.
 *      

 *           
 deleteDocumentLinkCallable()
 *      
 *       
 *
 * 
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 DocumentLinkServiceSettings to
 * create(). For example:
 *
 * 
To customize credentials:
 *
 * 
{@code
 * // 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
 * DocumentLinkServiceSettings documentLinkServiceSettings =
 *     DocumentLinkServiceSettings.newBuilder()
 *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
 *         .build();
 * DocumentLinkServiceClient documentLinkServiceClient =
 *     DocumentLinkServiceClient.create(documentLinkServiceSettings);
 * }
 *
 * 
To customize the endpoint:
 *
 * 
{@code
 * // 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
 * DocumentLinkServiceSettings documentLinkServiceSettings =
 *     DocumentLinkServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 * DocumentLinkServiceClient documentLinkServiceClient =
 *     DocumentLinkServiceClient.create(documentLinkServiceSettings);
 * }
 *
 * 
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
 * the wire:
 *
 * 
{@code
 * // 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
 * DocumentLinkServiceSettings documentLinkServiceSettings =
 *     DocumentLinkServiceSettings.newHttpJsonBuilder().build();
 * DocumentLinkServiceClient documentLinkServiceClient =
 *     DocumentLinkServiceClient.create(documentLinkServiceSettings);
 * }
 *
 * 
Please refer to the GitHub repository's samples for more quickstart code snippets.
