Method Detail

print

public static void print(@Param.Out
                         Appendable buffer,
                         Throwable t)

print StackTrace to buffer in 5-StackTrace (except root cause), Reversed, Shorten. And filename only in 1st stack, full stack only in root cause.

Parameters:

buffer - to write

t - throwable

print

public static void print(@Param.Out
                         Appendable buffer,
                         Throwable t,
                         boolean reverse,
                         boolean shorten)

print StackTrace to buffer. but filename only in 1st stack, full stack only in root cause.

Parameters:

buffer - to write

t - throwable

reverse - reverse the stack

shorten - shorten the class

print

public static void print(@Param.Out
                         Appendable buffer,
                         Throwable t,
                         boolean reverse,
                         boolean shorten,
                         int maxStack,
                         int maxCause)

print StackTrace to buffer. but filename only in 1st stack, full stack only in root cause.

Parameters:

buffer - to write

t - throwable

reverse - reverse the stack

shorten - shorten the class

maxStack - max Stack (except root cause) to print, default Integer#MAX_VALUE

maxCause - max Cause to print, default Integer#MAX_VALUE

toString

@NotNull
public static @NotNull String toString(Throwable t)

print StackTrace to String

rootString

@NotNull
public static @NotNull String rootString(Throwable t)

print root StackTrace to String

root

@Contract(value="!null->!null")
public static Throwable root(Throwable t)

get the root StackTrace which is the root cause.

contains
