org.josql.filters
Class StackTraceElementFilter  

java.lang.Object
  org.josql.filters.AbstractJoSQLFilter
      org.josql.filters.StackTraceElementFilter

---

public class StackTraceElementFilter

extends AbstractJoSQLFilter

This class allows you to filter the stack trace of a Throwable, so cutting down on the (sometimes) pointless long stack traces.

Usage:

    SELECT *
    FROM   java.lang.StackTraceElement
    WHERE  className LIKE 'org.josql.%'
 

And then to use in code:

    StackTraceElementFilter f = new StackTraceElementFilter (sql);
    f.filter (new Throwable ());
