Description

The list of methods to do Stacktrace are organized into topic(s).

Method

StringstackTrace2String(Throwable e)
make exception stack trace become string 
StringBuffer sb = new StringBuffer();
sb.append(e.toString()).append("\r\n");
StackTraceElement[] traces = e.getStackTrace();
for (StackTraceElement trace : traces) {
    sb.append(trace.toString()).append("\r\n");
return sb.toString();
booleanstackTraceApproved(StackTraceElement elt, String[] approved)
stack Trace Approved 
String className = elt.getClassName();
for (int i = 0; i < approved.length; i++) {
    String s = approved[i];
    if (className.startsWith(s))
        return true;
return false;
StringstackTraceAsString(Throwable t)
stack Trace As String 
StringBuilder sb = new StringBuilder();
sb.append(t.getClass().getName()).append(": ").append(t.getMessage());
for (StackTraceElement e : t.getStackTrace()) {
    sb.append("\n");
    sb.append(e.toString());
return sb.toString();
booleanstackTraceContainsCause(Throwable throwable, Class searchedCause)
Check if the stack trace of provided exception contains a given cause. 
Throwable t = throwable;
while ((t = t.getCause()) != null) {
    if (searchedCause.isAssignableFrom(t.getClass())) {
        return true;
return false;
StringstackTraceElementToString(StackTraceElement element)
stack Trace Element To String 
String methodName = element.getMethodName();
if (methodName == null || UNKNOWN.equals(methodName))
    return null;
String frame = "    at ";
String className = element.getClassName();
if (className != null && !UNKNOWN.equals(className))
    frame += className + ".";
frame += methodName + "(";
...
StringstackTraceElementWithLinenumber(StackTraceElement stackTraceElement)
Generates a string from trace for the current class with linenumber. 
if (null != stackTraceElement) {
    return stackTraceElement.getClassName() + LINE_NUMBER_SEPARATOR + stackTraceElement.getLineNumber();
} else {
    return "Internal ERROR stackTraceElement should not be null";
StringstackTraceElementWithLinenumberAsString(StackTraceElement stackTraceElement)
stack Trace Element With Linenumber As String 
if (null != stackTraceElement) {
    return stackTraceElement.getClassName() + LINE_NUMBER_SEPARATOR + stackTraceElement.getLineNumber();
} else {
    return "Internal ERROR stackTraceElement should not be null";
booleanstackTraceEquals(StackTraceElement[] ta1, StackTraceElement[] ta2)
Compares two stack traces and checks if they are equal 
if (ta1 == ta2) {
    return true;
if (ta1.length == ta2.length) {
    for (int i = 0, lnLength = ta1.length; i < lnLength; i++) {
        if (!equals(ta1[i], ta2[i])) {
            return false;
    return true;
return false;
StringstackTraceGenerate()
stack Trace Generate 
StackTraceElement[] steArr = Thread.currentThread().getStackTrace();
String ret = "";
for (StackTraceElement ste : steArr) {
    ret += ste.toString() + "\n";
return ret;
