public abstract class BigQueryClient : IDisposable
Reference documentation and code samples for the Google BigQuery v2 API class BigQueryClient.
Abstract class providing operations for Google Cloud BigQuery.
Implements
IDisposableDerived Types
Namespace
GoogleGoogle.CloudGoogle.Cloud.BigQueryV2Assembly
Google.Cloud.BigQuery.V2.dll
Remarks
This abstract class is provided to enable testability while permitting additional operations to be added in the future. See Create(string, GoogleCredential) and CreateAsync(string, GoogleCredential) to construct instances; alternatively, you can construct a BigQueryClientImpl directly from a BigqueryService.
All instance methods declared in this class are virtual, with an implementation which simply throws NotImplementedException. All these methods are overridden in BigQueryClientImpl.
This class implements IDisposable; however, the Dispose() method only requires calling
if many short-lived instances of BigQueryClient are being created.
Most code would be expected to create a single BigQueryClient
instance, and use this instance throughout
the lifetime of the application. In this case, Dispose
need not be called.
Properties
DefaultLocation
public virtual string DefaultLocation { get; }
The default location to use for all operations where locations can be specified, such as dataset and job creation.
Property Value | |
---|---|
Type | Description |
string |
PrettyPrint
public virtual bool PrettyPrint { get; }
Determines whether or not responses should be formatted with whitespace for readability.
Property Value | |
---|---|
Type | Description |
bool |
ProjectId
public virtual string ProjectId { get; }
The ID of the project this client operates on. All operations that require a project to be specified implicitly supply this ID.
Property Value | |
---|---|
Type | Description |
string |
Service
public virtual BigqueryService Service { get; }
The underlying BigQuery service object used by this client.
Property Value | |
---|---|
Type | Description |
BigqueryService |
The BigQueryClient class only provides convenience operations built on top of an existing service object. Any more complex operations which are not supported by this wrapper may wish to use the same service object as the wrapper, in order to take advantage of its configuration (for authentication, application naming etc).
