Constructor Details

#initialize {|config| ... } ⇒ Client

Create a new LanguageService client object.

Examples

To create a new LanguageService client with the default configuration:

client = ::Google::Cloud::Language::V1beta2::LanguageService::Client.new

To create a new LanguageService client with a custom configuration:

client = ::Google::Cloud::Language::V1beta2::LanguageService::Client.new do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the LanguageService client.

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

Configure the LanguageService 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.
