Examples of com.sun.enterprise.admin.event.AdminEventResult

com.sun.enterprise.admin.event.AdminEventResult
Admin Event Result objects are used to communicate result of admin event notification. AdminEventResult object can be either used to represent composite result of multiple instances. getResultCode() returns one of the valid result codes either ERROR, SUCCESS or others like TRANSMISSION_ERROR, RESTART_NEEDED etc. This is composite result of all event's recipients' results. In order to get individual recipient's result getResultCodes() can be used. It returns hash map of instance name and result code. If some recipients got the notification and the others did not receive the notification or failed to process it for any reason.The composite result would be MIXED_RESULT. Similarly hash map of messages and exceptions can be obtained using getMessages and getExceptions respectively. All the methods (setters/getters) of AdminEventResult (except setResultCode and getResultCode) take instance name as argument. Helper methods are also available to format the results and messages/exceptions into a string format. Please look at getAllResultCodesAsString() and getAllMessagesAsString() for details. This class is not thread safe and usage from AdminEventMulticaster does not require it to be thread safe. The methods add/remove Attribute do synchronize internally but that might not be sufficient.
