Interface ErrorInfo

public interface ErrorInfo

The ErrorInfo interface defines a container which carries error information for specific message implementations in a generic way. Message implementation specific ErrorInfo container implementations can be retrieved from a given message with the createErrorInfo method and maintained as part of a message with the setter and getter method.
There's an default implementation of the ErrorInfo container just simply based on a Hashmap with setter and getter methods for arbitrary error attributes. Each protocol (message format implementation) should extend this abstract ErrorInfo implementation and offer convenience methods for setting and getting the protocol specific error information attributes (if the protocol supports explicit error messages).

Method Summary

Modifier and Type	Method and Description

String[]	getSupportedAttributeNames() This method can be overwritten by the protocol specific ErrorInfo container implementations to specify, which attribute names are known by the setAttribute method.
void	setAttribute(String name, String value) Sets an ErrorInfo attribute.
