From: Roland Haeder Date: Thu, 16 Jul 2015 06:26:25 +0000 (+0200) Subject: Made getMenu() abstract as showMenu() is now in BaseClient. This has the benefit... X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=6aee766f085ca3c6da8191b0f3d371585fbc6cdc;p=addressbook-lib.git Made getMenu() abstract as showMenu() is now in BaseClient. This has the benefit that generic code doesn't need to be repeated (DRY).
