Overview

Client for the DocumentProcessorService service.

Service to call Cloud DocumentAI to process documents according to the processor's definition. Processors are built using state-of-the-art Google AI such as natural language, computer vision, and translation to extract structured information from unstructured or semi-structured documents.

Constructor Details

#initialize {|config| ... } ⇒ Client

Create a new DocumentProcessorService client object.

Examples

To create a new DocumentProcessorService client with the default configuration:

client = ::Google::Cloud::DocumentAI::V1beta3::DocumentProcessorService::Client.new

To create a new DocumentProcessorService client with a custom configuration:

client = ::Google::Cloud::DocumentAI::V1beta3::DocumentProcessorService::Client.new do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the DocumentProcessorService client.

Instance Method Details

#batch_process_documents(request, options = nil) ⇒ ::Gapic::Operation #batch_process_documents(name: nil, input_configs: nil, output_config: nil, input_documents: nil, document_output_config: nil, skip_human_review: nil) ⇒ ::Gapic::Operation

LRO endpoint to batch process many documents. The output is written to Cloud Storage as JSON in the [Document] format.

Overloads:

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

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

    Parameters:

    • request (::Google::Cloud::DocumentAI::V1beta3::BatchProcessRequest, ::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.

  • #batch_process_documents(name: nil, input_configs: nil, output_config: nil, input_documents: nil, document_output_config: nil, skip_human_review: nil) ⇒ ::Gapic::Operation

    Pass arguments to batch_process_documents 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:

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.

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.
