Subject: [1608] moved RBNodeRRset internals to the in-memory implementation file.
X-Git-Tag: trac2351_base~226^2~116^2~127^2~3^2~17
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=fe8e4b87d5b493fa2cf41f1e8dce1b5809c27679;p=thirdparty%2Fkea.git

[1608] moved RBNodeRRset internals to the in-memory implementation file.
For that purpose RBNodeRRsetImpl structure was introduced.
no functional change.
