public static java.lang.String exceptionInfo(java.lang.Exception e,
                                             java.lang.String title)

id

public static java.lang.String id(java.lang.Object object)

A value that uniquely identifies the object within its class.

Returns:

Prints a useful,truncated stack trace.

Parameters:

printLines - how many lines of the trace to print

printStackTrace

public static void printStackTrace(java.lang.String stopText)

Prints useful stack trace up to eg a method name.

Parameters:

stopText - occurring in a line stops further lines appearing
