    • handleMessage

      public abstract boolean handleMessage(String command, com.fasterxml.jackson.databind.JsonNode data, com.vaadin.base.devserver.DevToolsInterface devToolsInterface)
      Called whenever there is a message from the browser. Implementations should check if the command is for them, handle it and return true if the command was handled.
      Parameters:
      command - the command to handle
      data - the data for the command
      devToolsInterface - the devtools interface for the connection
      Returns:
      true if the command was handled, false otherwise

    • handleConnect

      public void handleConnect(com.vaadin.base.devserver.DevToolsInterface devToolsInterface)
      Called when a new browser (tab) connects to the server. Override to add logic that should run on every connect.
      Parameters:
      devToolsInterface - the devtools interface for the new connection

    • canBeParallelCommand

      public boolean canBeParallelCommand(String command)
      Checks if given command can be handled asynchronously. If the handler can't be asynchronous at all, it can return false always. But if you want to handle one or more commands asynchronously, you should specify the exact command to prevent handling commands that are not part of the handler as asynchronous.
      Parameters:
      command - the command to check
      Returns:
      true if the command can be handled by this command handler
