Constructor Details

#initialize {|config| ... } ⇒ Client

Create a new Locations client object.

Examples:


# Create a client using the default configuration
client = ::Google::Cloud::Location::Locations::Client.new

# Create a client using a custom configuration
client = ::Google::Cloud::Location::Locations::Client.new do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the Locations client.

Instance Method Details

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

Configure the Locations 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.

Yield Parameters:

Returns:

#get_location(request, options = nil) ⇒ ::Google::Cloud::Location::Location #get_location(name: nil) ⇒ ::Google::Cloud::Location::Location

Gets information about a location.

Examples:

Basic example

require "google/cloud/location"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Location::Locations::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Location::GetLocationRequest.new

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

# The returned object is of type Google::Cloud::Location::Location.
p result

Overloads:

  • #get_location(request, options = nil) ⇒ ::Google::Cloud::Location::Location

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

    Parameters:

    • request (::Google::Cloud::Location::GetLocationRequest, ::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.

  • #get_location(name: nil) ⇒ ::Google::Cloud::Location::Location

    Pass arguments to get_location 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:

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

      Resource name for the location.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

Lists information about the supported locations for this service.

Examples:

Basic example

require "google/cloud/location"

# Create a client object. The client can be reused for multiple calls.

# The returned object is of type Gapic::PagedEnumerable. You can iterate
# over elements, and API calls will be issued to fetch pages as needed.
result.each do |item|
  # Each element is of type ::Google::Cloud::Location::Location.
  p item
end

Overloads:

  • #list_locations(request, options = nil) ⇒ ::Gapic::PagedEnumerable<::Google::Cloud::Location::Location>

    Pass arguments to list_locations via a request object, either of type Google::Cloud::Location::ListLocationsRequest or an equivalent Hash.

    Parameters:

    Pass arguments to list_locations 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:

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

      The resource that owns the locations collection, if applicable.

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