/** @module config */
import { StringValueMap } from 'pip-services4-commons-node';
/**
 * Contains a key-value map with configuration parameters.
 * All values stored as strings and can be serialized as JSON or string forms.
 * When retrieved the values can be automatically converted on read using GetAsXXX methods.
 *
 * The keys are case-sensitive, so it is recommended to use consistent C-style as: <code>"my_param"</code>
 *
 * Configuration parameters can be broken into sections and subsections using dot notation as:
 * <code>"section1.subsection1.param1"</code>. Using GetSection method all parameters from specified section
 * can be extracted from a ConfigMap.
 *
 * The ConfigParams supports serialization from/to plain strings as:
 * <code>"key1=123;key2=ABC;key3=2016-09-16T00:00:00.00Z"</code>
 *
 * ConfigParams are used to pass configurations to [[IConfigurable]] objects.
 * They also serve as a basis for more concrete configurations such as [[https://pip-services4-node.github.io/pip-services4-components-node/classes/connect.connectionparams.html ConnectionParams]]
 * or [[https://pip-services4-node.github.io/pip-services4-components-node/classes/auth.credentialparams.html CredentialParams]] (in the Pip.Services components package).
 *
 * @see [[IConfigurable]]
 * @see [[StringValueMap]]
 *
 * ### Example ###
 *
 *     let config = ConfigParams.fromTuples(
 *         "section1.key1", "AAA",
 *         "section1.key2", 123,
 *         "section2.key1", true
 *     );
 *
 *     config.getAsString("section1.key1"); // Result: AAA
 *     config.getAsInteger("section1.key1"); // Result: 0
 *
 *     section1 = config.getSection("section1");
 *     section1.toString(); // Result: key1=AAA;key2=123
