Examples with Parameters io.helidon.common.http.Parameters used on opensource projects

Example 1 with Parameters

use of io.helidon.common.http.Parameters in project helidon by oracle.

the class Main method parametersAndHeaders.

/**
 * {@link io.helidon.webserver.ServerRequest ServerRequest} provides access to three types of "parameters":
 * <ul>
 *     <li>Headers</li>
 *     <li>Query parameters</li>
 *     <li>Path parameters - <i>Evaluated from provided {@code path pattern}</i></li>
 * </ul>
 * <p>
 * {@link java.util.Optional Optional} API is heavily used to represent parameters optionality.
 * <p>
 * WebServer {@link Parameters Parameters} API is used to represent fact, that <i>headers</i> and
 * <i>query parameters</i> can contain multiple values.
