Example 1 with StringStateValue

use of org.rstudio.studio.client.workbench.model.helper.StringStateValue in project rstudio by rstudio.

the class Shell method sessionInit.

private void sessionInit(Session session) {
    SessionInfo sessionInfo = session.getSessionInfo();
    ClientInitState clientState = sessionInfo.getClientState();
    new StringStateValue(GROUP_CONSOLE, STATE_INPUT, ClientState.TEMPORARY, clientState) {

            initialInput_ = value;
        }

        @Override
        protected String getValue() {

    if (sessionInfo.getResumed()) {
    // no special UI for this (resuming session with all console
    // history and other UI state preserved deemed adequate feedback)
