Description
If I'm writing a custom Java Embedded Adapter, I call com.streambase.sb.operator.Operator.getLogger().
How do I get a reference to the current logger from a custom Java Function which does not have access to the Operator class?
Resolution
Here is an example based on the code generated by the Java Function Wizard
This function, for example, can then be used in a Map operator expression as:
The Function Wizard in Studio creates the necessary configuration file settings to access the function from within the EventFlow application.
package com.sb.support;
import org.slf4j.*;
public class LogIt {
public static boolean logWarn(String arg0) {
final Logger logger = LoggerFactory.getLogger(LogIt.class);
logger.warn(arg0);
return true;
}
}
This function, for example, can then be used in a Map operator expression as:
calljava("com.sb.support.LogIt","logWarn","Hello Test")
The Function Wizard in Studio creates the necessary configuration file settings to access the function from within the EventFlow application.
