Method Details

getAncestor

public static <T extends Throwable> T getAncestor(Class<T> cl,
 Throwable t)

Returns the most recent Throwable of class T in the proper causal history of the given Throwable, if one exists.

Parameters:

cl - the Class to search for

t - the Throwable to check

Returns:

the proper ancestor of class T, or null if none exists

getRecent

public static <T extends Throwable> T getRecent(Class<T> cl,
 Throwable t)

Returns the most recent Throwable of class T in the (not necessarily proper) causal history of the given Throwable, if one exists. If the given Throwable is of class T, it will be returned.

Parameters:

cl - the Class to search for

t - the Throwable to check

Returns:

the ancestor of class T, or null if none exists

throwAncestor

public static <T extends Throwable> void throwAncestor(Class<T> cl,
 Throwable t)
                                                throws T

Throws the most recent Throwable of class T in the proper causal history of the given Throwable, if one exists.

Parameters:

cl - the Class to search for

t - the Throwable to check

Throws:

T - if an ancestor of that class is found

throwRecent

public static <T extends Throwable> void throwRecent(Class<T> cl,
 Throwable t)
                                              throws T

Throws the most recent Throwable of class T in the (not necessarily proper) causal history of the given Throwable, if one exists.

Parameters:

cl - the Class to search for

t - the Throwable to check

Throws:

T - if an ancestor of that class is found

getStackTrace

public static String getStackTrace(Throwable thrown)

Converts a Throwable's stack trace to a String.

Parameters:

thrown - the Throwable with the stack trace to convert

Returns:

the stack trace as a String
