Document

Returns the fully qualified name of the class containing the execution point represented by this stack trace element.

Usage

From source file:com.openkm.util.StackTraceUtils.java

/**
 * Return the method who make the call./*from www.  ja  v  a2s  .com*/
 */
public static void logTrace(Logger log) {
    // The constructor for Throwable has a native function that fills the stack trace.
    StackTraceElement[] trace = (new Throwable()).getStackTrace();

    // Once you have the trace you can pick out information you need.
    if (trace.length >= 2) {
        for (int i = 2; i < trace.length; i++) {
            if (trace[i].getClassName().startsWith("com.openkm")) {
                StackTraceElement sse = trace[i];
                log.warn("{} -> {} ({}:{})", new Object[] { sse.getClassName(), sse.getMethodName(),
                        sse.getFileName(), sse.getLineNumber() });
