Subject: Reworked the event class
X-Git-Url: https://gerrit.automotivelinux.org/gerrit/gitweb?p=src%2Fapp-framework-binder.git;a=commitdiff_plain;h=4b0cfc57651134044d11c0803f7140616dc25dfe

Reworked the event class

Added move semantic and remove invalidation method as it's not used anymore
since we drop the support of APIv2.
