Subject: [OASIS Issue Tracker] Updated: (ODATA-395) Simplify rule for implicit values of enumeration members
[ http://tools.oasis-open.org/issues/browse/ODATA-395?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Ralf Handl updated ODATA-395: ----------------------------- Proposal: Require that the Value attribute must be specified either for all members or for no member if IsFlags="false". If no values are specified, the members are consecutively numbered in document order, starting with zero. Note: Value is already required for all members if IsFlags="true". Accepted: https://www.oasis-open.org/committees/download.php/49325/odata-meeting-38_on-20130523-minutes.html#odata-395 was: Require that the Value attribute must be specified either for all members or for no member if IsFlags="false". If no values are specified, the members are consecutively numbered in document order, starting with zero. Note: Value is already required for all members if IsFlags="true". > Simplify rule for implicit values of enumeration members > -------------------------------------------------------- > > Key: ODATA-395 > URL: http://tools.oasis-open.org/issues/browse/ODATA-395 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: Improvement > Components: OData CSDL > Affects Versions: V4.0_CSD01 > Environment: [Proposed] > Reporter: Ralf Handl > Fix For: V4.0_CSD02 > > > Enumeration members have an optional Value attribute for specifying an integer equivalent to the symbolic member name that is for ordering. > The current rule for implicitly numbering the enumeration members is cloned from the C family of programming languages and allows specifying values for some members while having the other members being numbered implicitly. This can lead to surprising results for the uninitiated: > <EnumType Name="ShippingMethod"> > <Member Name="VIP"/> > <Member Name="FirstClass"/> > <Member Name="TwoDay" Value="0"/> > <Member Name="Overnight"/> > </EnumType> > The result is that both VIP and TwoDay get the value zero and both FirstClass and Overnight get the value 1. > While we see value in having Value optional, we see no value in providing a value for some members only. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
