Examples with Encoder jakarta.websocket.Encoder used on opensource projects

Example 1 with Encoder

use of jakarta.websocket.Encoder in project tomcat by apache.

the class WsServerContainer method validateEncoders.

private static void validateEncoders(Class<? extends Encoder>[] encoders, InstanceManager instanceManager) throws DeploymentException {
    for (Class<? extends Encoder> encoder : encoders) {
        // Need to instantiate encoder to ensure it is valid and that
        // deployment can be failed if it is not. The encoder is then
        // discarded immediately.
        Encoder instance;
        try {
            if (instanceManager == null) {
