Examples of org.apache.hivemind.ErrorHandler

org.apache.hivemind.ErrorHandler
Interface for handling recoverable errors. Recoverable errors are often caused by improper configuration data in a module descriptor. Implementations of this interface can either be brittle (throw an ApplicationRuntimeException immediately) or "mellow" and just log the exception (with the expectation that a more drastic failure may follow later). @author Howard Lewis Ship
