Interface WrapsException

All Known Implementing Classes:

BuckUncheckedExecutionException, BuildRuleFailedException, StepFailedException

public interface WrapsException

This interface indicates that an exception is just used to wrap another and isn't the true root cause of the problem. This is used to present the exception in a more user-friendly way.

Method Summary

Modifier and Type	Method and Description
static Throwable	getRootCause(Throwable throwable) Unwraps exception to the root cause.

Method Detail

getRootCause

static Throwable getRootCause(Throwable throwable)

Unwraps exception to the root cause.

TODO(cjhopman): This behavior is slightly different than that in ErrorLogger as it doesn't unwrap the non-WrapsException exceptions that ErrorLogger does.
