Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the EngineService Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

#create_engine(request, options = nil) ⇒ ::Gapic::Operation #create_engine(parent: nil, engine: nil, engine_id: nil) ⇒ ::Gapic::Operation

Creates a Engine.

Examples:

Basic example

require "google/cloud/discovery_engine/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::DiscoveryEngine::V1::EngineService::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::DiscoveryEngine::V1::CreateEngineRequest.new

# Call the create_engine method.
result = client.create_engine request

# The returned object is of type Gapic::Operation. You can use it to
# check the status of an operation, cancel it, or wait for results.
# Here is how to wait for a response.
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "No response received."
end

Overloads:

  • #create_engine(request, options = nil) ⇒ ::Gapic::Operation

    Pass arguments to create_engine via a request object, either of type CreateEngineRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::DiscoveryEngine::V1::CreateEngineRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #create_engine(parent: nil, engine: nil, engine_id: nil) ⇒ ::Gapic::Operation

    Pass arguments to create_engine via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • parent (::String) (defaults to: nil) —

      Required. The parent resource name, such as projects/{project}/locations/{location}/collections/{collection}.

    • engine (::Google::Cloud::DiscoveryEngine::V1::Engine, ::Hash) (defaults to: nil) —

      Required. The Engine to create.

    • engine_id (::String) (defaults to: nil) —

      Required. The ID to use for the Engine, which will become the final component of the Engine's resource name.

      This field must conform to RFC-1034 standard with a length limit of 63 characters. Otherwise, an INVALID_ARGUMENT error is returned.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

  • response (::Gapic::Operation)
  • operation (::GRPC::ActiveCall::Operation)

Returns:

  • (::Gapic::Operation)

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#update_engine(request, options = nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1::Engine #update_engine(engine: nil, update_mask: nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1::Engine

Updates an Engine

Examples:

Basic example

require "google/cloud/discovery_engine/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::DiscoveryEngine::V1::EngineService::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::DiscoveryEngine::V1::UpdateEngineRequest.new

# Call the update_engine method.
result = client.update_engine request

# The returned object is of type Google::Cloud::DiscoveryEngine::V1::Engine.
p result

Overloads:

  • #update_engine(request, options = nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1::Engine

    Pass arguments to update_engine via a request object, either of type UpdateEngineRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::DiscoveryEngine::V1::UpdateEngineRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #update_engine(engine: nil, update_mask: nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1::Engine

    Pass arguments to update_engine via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • engine (::Google::Cloud::DiscoveryEngine::V1::Engine, ::Hash) (defaults to: nil) —

      Required. The Engine to update.

      If the caller does not have permission to update the Engine, regardless of whether or not it exists, a PERMISSION_DENIED error is returned.

      If the Engine to update does not exist, a NOT_FOUND error is returned.

    • update_mask (::Google::Protobuf::FieldMask, ::Hash) (defaults to: nil) —

      Indicates which fields in the provided Engine to update.

      If an unsupported or unknown field is provided, an INVALID_ARGUMENT error is returned.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
