Method Details

getCurrentStackTrace

public static StackTraceElement[] getCurrentStackTrace()

Returns current stack trace in form of array of stack trace elements. First stack trace element is removed. Since an exception is thrown internally, this method is slow.

getStackTrace

public static StackTraceElement[] getStackTrace(Throwable t,
 String[] allow,
 String[] deny)

Returns stack trace filtered by class names.

getStackTraceChain

public static StackTraceElement[][] getStackTraceChain(Throwable t,
 String[] allow,
 String[] deny)

Returns stack trace chain filtered by class names.

getExceptionChain

public static Throwable[] getExceptionChain(Throwable throwable)

Returns exception chain starting from top up to root cause.

exceptionStackTraceToString

public static String exceptionStackTraceToString(Throwable t)

Prints stack trace into a String.

exceptionChainToString

public static String exceptionChainToString(Throwable t)

Prints full exception stack trace, from top to root cause, into a String.

buildMessage

public static String buildMessage(String message,
 Throwable cause)

Build a message for the given base message and its cause.

getRootCause

public static Throwable getRootCause(Throwable throwable)

Introspects the Throwable to obtain the root cause.

This method walks through the exception chain to the last element, "root" of the tree, and returns that exception. If no root cause found returns provided throwable.

findCause

public static <T extends Throwable> T findCause(Throwable throwable,
 Class<T> cause)

Finds throwing cause in exception stack. Returns throwable object if cause class is matched. Otherwise, returns null.

rollupSqlExceptions

public static SQLException rollupSqlExceptions(Collection<SQLException> exceptions)

Rolls up SQL exceptions by taking each proceeding exception and making it a child of the previous using the setNextException method of SQLException.

throwRuntimeException

public static void throwRuntimeException(Throwable throwable)

Throws checked exceptions in un-checked manner.

message

public static String message(Throwable throwable)

Returns non-null message for a throwable.

wrapToRuntimeException

public static RuntimeException wrapToRuntimeException(Throwable throwable)

Wraps exception to RuntimeException.

wrapToException

public static Exception wrapToException(Throwable throwable)

unwrapThrowable

public static Throwable unwrapThrowable(Throwable wrappedThrowable)

Unwraps invocation and undeclared exceptions to real cause.
