Java Edit Variable: Set progress.

Node Development

Hi All, is there a way to get an ExecutionMonitor in the java edit variable node? I’ve got a long running node with some detailed information about it’s progress and I don’t want to spam logger.warn(). Any hints?

Hi Aaron,
I don’t think it is possible to get the execution monitor. The code generated by the snippet looks like this:

public class JSnippet extends AbstractJSnippet {

    // Fields for output flow variables
    /** Output flow variable: "test" */
    public Double out_test;

    // Your custom variables:

    // expression start
    public void snippet() throws TypeException, ColumnException, Abort {
        // Enter your code here:
        out_test = 99.97;
        // expression end
    }
}

The snippet method does not have access to the ExecutionContext and the AbstractJSnippet doesn’t know it either :frowning:
Kind regards
Alex

You could create you own instance of NodeLogger that is configured to log somewhere other than the KNIME console, and then hand that off to your snippet’s parent class via attachLogger(NodeLogger)

That’s an interesting idea, thanks!
