29 System Settings API

This chapter provides a use case for the System Settings API that describes how to query for system settings in Oracle Enterprise Repository.

This chapter includes the following sections:

• Section 29.1, "Overview"

• Section 29.2, "Use Case"

29.1 Overview

Within the Oracle Enterprise Repository's System Settings section administrators can configure the basic operations and enable/disable specific features. The System Settings API provides a mechanism to query these system settings.

Note:

Users are allowed only to query the system settings for values, the system settings cannot be set or modified through REX.

To query the system settings, the following package import(s) are required:

import com.flashline.registry.openapi.entity.SettingValue;
import com.flashline.registry.openapi.entity.AuthToken;
import com.flashline.registry.openapi.query.SystemSettingsCriteria;

Reserved Methods

The systemSettingsAddBundle method is reserved for future use and is not intended for general use.

29.2 Use Case

This section describes a use case using the System Settings API. It includes the following topic:

• Section 29.2.1, "Use Case: Query for System Settings"

29.2.1 Use Case: Query for System Settings

Description
