public class StackTraceFilter
extends Object

Filtering Facility for stack traces. This is to shorten very long Traces. It creates a redacted trace containing only the interesting parts. Please provide an own Resource /StackTraceFilter.packages with the package prefixes if you want to use a custom filter (one package per line). # Packages to filter org.h2 org.apache.catalina

Method Detail

loadSetttings

public static void loadSetttings(String resourceName)

getDefaults

public static List<String> getDefaults()

getFilteredStackTrace

public static String getFilteredStackTrace(Throwable t)

Get a filterered stack trace.

Parameters:

t - the throwable

Returns:

String containing the filtered stack trace.

getFilteredStackTrace

@Deprecated
public static String getFilteredStackTrace(Throwable t,
                                                       boolean shouldFilter)

Deprecated. since 1.11.1. Use getStackTrace(Throwable, int) to get the stack trace without filtering or getFilteredStackTrace(Throwable) to get the filtered the stack trace.

Get a filterered stack trace.

Parameters:

t - the throwable

shouldFilter - true in case filtering should be performed. Else stack trace as string will be returned.

Returns:

String containing the stack trace.

getFilteredStackTrace

public static String getFilteredStackTrace(Throwable t,
                                           int ref)

Filter stack trace by selecting the Throwable using a reference position. Intermediate throwables will be printed with just their header.

Parameters:

t - the throwable

ref - throwable reference position, see getThrowable(List, int).

Returns:

String containing the stack trace.

Since:

1.11.1

getStackTrace

public static String getStackTrace(Throwable t)

Get the Throwable's stack trace.

Parameters:

t - the throwable

Returns:

String containing the stack trace.

Since:

1.11.1

getStackTrace

public static String getStackTrace(Throwable t,
                                   int ref)

Get the stack trace by selecting the Throwable using a reference position. Intermediate throwables will be printed with just their header.

Parameters:

t - the throwable

ref - throwable reference position, see getThrowable(List, int).

Returns:

String containing the stack trace.

Since:

1.11.1

getThrowable

public static Throwable getThrowable(Throwable throwable,
                                     int ref)

Return a Throwable by its reference position.

This method extracts a Throwable from the exception chain of causes. A reference of 0 returns the original Throwable, values greater zero will walk the cause chain up so a reference 1 returns t.getCause(). Negative reference values will walk the causing exception from the root cause side. A reference of -1 returns the root cause, -2 the exception that wraps the root cause and so on.

Parameters:

throwable - the caught Throwable.

ref - reference position

Returns:

the selected Throwable.
