MetadataServiceClient (Google Cloud Vertex AI 3.0.0 API)

java.lang.Object
- com.google.cloud.aiplatform.v1.MetadataServiceClient

All Implemented Interfaces:

com.google.api.gax.core.BackgroundResource, AutoCloseable
```
@Generated(value="by gapic-generator-java")
public class MetadataServiceClient
extends Object
implements com.google.api.gax.core.BackgroundResource
```
Service Description: Service for reading and writing metadata entries.
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 for illustrative purposes only.
 // It may require modifications to work in your environment.
 try (MetadataServiceClient metadataServiceClient = MetadataServiceClient.create()) {
   MetadataStoreName name = MetadataStoreName.of("[PROJECT]", "[LOCATION]", "[METADATA_STORE]");
   MetadataStore response = metadataServiceClient.getMetadataStore(name);
 }
 
```
Note: close() needs to be called on the MetadataServiceClient 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 MetadataServiceSettings to create(). For example:
To customize credentials:
```
 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 MetadataServiceSettings metadataServiceSettings =
     MetadataServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 MetadataServiceClient metadataServiceClient =
     MetadataServiceClient.create(metadataServiceSettings);
 
```
To customize the endpoint:
```
 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 MetadataServiceSettings metadataServiceSettings =
     MetadataServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 MetadataServiceClient metadataServiceClient =
     MetadataServiceClient.create(metadataServiceSettings);
 
```

Initializes a MetadataStore, including allocation of resources.

Sample code:


 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 try (MetadataServiceClient metadataServiceClient = MetadataServiceClient.create()) {
   LocationName parent = LocationName.of("[PROJECT]", "[LOCATION]");
   MetadataStore metadataStore = MetadataStore.newBuilder().build();
   String metadataStoreId = "metadataStoreId-1811789907";
   MetadataStore response =
       metadataServiceClient
           .createMetadataStoreAsync(parent, metadataStore, metadataStoreId)
           .get();
 }

Parameters:: parent - Required. The resource name of the Location where the MetadataStore should be created. Format: `projects/{project}/locations/{location}/`; metadataStore - Required. The MetadataStore to create.; metadataStoreId - The {metadatastore} portion of the resource name with the format: `projects/{project}/locations/{location}/metadataStores/{metadatastore}` If not provided, the MetadataStore's ID will be a UUID generated by the service. Must be 4-128 characters in length. Valid characters are `/[a-z][0-9]-/`. Must be unique across all MetadataStores in the parent Location. (Otherwise the request will fail with ALREADY_EXISTS, or PERMISSION_DENIED if the caller can't view the preexisting MetadataStore.)

       MetadataStoreName.of("[PROJECT]", "[LOCATION]", "[METADATA_STORE]").toString();
   Execution execution = Execution.newBuilder().build();
   String executionId = "executionId-454906285";
   Execution response = metadataServiceClient.createExecution(parent, execution, executionId);
 }
 
```
Parameters:

parent - Required. The resource name of the MetadataStore where the Execution should be created. Format: `projects/{project}/locations/{location}/metadataStores/{metadatastore}`

execution - Required. The Execution to create.

executionId - The {execution} portion of the resource name with the format: `projects/{project}/locations/{location}/metadataStores/{metadatastore}/executions/{execution}` If not provided, the Execution's ID will be a UUID generated by the service. Must be 4-128 characters in length. Valid characters are `/[a-z][0-9]-/`. Must be unique across all Executions in the parent MetadataStore. (Otherwise the request will fail with ALREADY_EXISTS, or PERMISSION_DENIED if the caller can't view the preexisting Execution.)

Throws:

com.google.api.gax.rpc.ApiException - if the remote call fails
