API for Amazon Comprehend¶

ABAP Package	`/AWS1/API_CPD_IMPL`
ABAP SDK "TLA"	`CPD`
ABAP Interface	`/AWS1/IF_CPD`

The "TLA" is a Three Letter Abbreviation that appears in ABAP class names, data dictionary objects and other ABAP objects throughout the AWS SDK for SAP ABAP. The TLA for Amazon Comprehend is CPD. This TLA helps squeeze ABAP objects into the 30-character length limit of the ABAP data dictionary.

Installation¶

To install the AWS SDK for SAP ABAP, import the Core transport, along with the transport for the Comprehend module and other API modules you are interested in. A few modules are included in the Core transport itself. For more information, see the Developer Guide guide.

About The Service¶

Amazon Comprehend is an Amazon Web Services service for gaining insight into the content of documents. Use these actions to determine the topics contained in your documents, the topics they discuss, the predominant sentiment expressed in them, the predominant language used, and more.

Using the SDK¶

In your code, create a client using the SDK module for Amazon Comprehend, which is created with factory method /AWS1/CL_CPD_FACTORY=>create(). In this example we will assume you have configured an SDK profile in transaction /AWS1/IMG called ZFINANCE.

DATA(go_session)   = /aws1/cl_rt_session_aws=>create( 'ZFINANCE' ).
DATA(go_cpd)       = /aws1/cl_cpd_factory=>create( go_session ).

Your variable go_cpd is an instance of /AWS1/IF_CPD, and all of the operations in the Amazon Comprehend service are accessed by calling methods in /AWS1/IF_CPD.

`IV_REGION` `TYPE` `/AWS1/RT_REGION_ID`¶

`IV_CUSTOM_ENDPOINT` `TYPE` `/AWS1/RT_ENDPOINT`¶

RETURNING¶

`OO_CLIENT` `TYPE REF TO` `/AWS1/IF_CPD`¶

/AWS1/IF_CPD represents the ABAP client for the Comprehend service, representing each operation as a method call. For more information see the API Page page.

Configuring Programmatically¶

DATA(lo_config) = DATA(go_cpd)->get_config( ).

lo_config is a variable of type /AWS1/CL_CPD_CONFIG. See the documentation for /AWS1/CL_CPD_CONFIG for details on the settings that can be configured.

Paginators¶

Paginators for Amazon Comprehend can be created via get_paginator() which returns a paginator object of type /AWS1/IF_CPD_PAGINATOR. The operation method that is being paginated is called using the paginator object, which accepts any necessary parameters to provide to the underlying API operation. This returns an iterator object which can be used to iterate over paginated results using has_next() and get_next() methods.

Details about the paginator methods available for service Amazon Comprehend can be found in interface /AWS1/IF_CPD_PAGINATOR.
