OpenGrok says that:
GetDomainName is only used by
GetYPDomainName
in the same file
which in turn is only used by
const rtl::OUString& SubstitutePathVariables_Impl::GetYPDomainName()
in
/core/framework/source/services/substitutepathvars.cxx
which in turn is only used by
bool SubstitutePathVariables_Impl::FilterRuleSet( const
SubstituteRuleVector& aRuleSet, SubstituteRule& aActiveRule )
in the same file.
and that particular codepath in that method is only referenced when the
enum EnvironmentType {
ET_YPDOMAIN
constant is used.
which in turn is not used anywhere in the LO codebase.
