Issue 17412: Spec lacks definition regarding uniqueness of InstanceHandle_t (data-distribution-rtf) Source: Remedy IT (Mr. Johnny Willemsen, jwillemsen(at)remedy.nl) Nature: Clarification Severity: Minor Summary: The spec defines the following: 7.1.2.1.1.8 get_instance_handle This operation returns the InstanceHandle_t that represents the Entity. But it doesn't specify in how far this InstanceHandle_t has to be unique. When the user receives an InstanceHandle_t, is it than unique within the same domain participant, within the process or within the complete dds domain? If it is for example just unique within one domain participant, we can't use it for example as key in a map which could contain entities from multiple domain participants Resolution: Revised Text: Actions taken: June 8, 2012: received issue Discussion: End of Annotations:===== m: webmaster@omg.org Date: 08 Jun 2012 02:38:22 -0400 To: Subject: Issue/Bug Report ******************************************************************************* Name: Johnny Willemsen Employer: Remedy IT mailFrom: jwillemsen@remedy.nl Terms_Agreement: I agree Specification: DDS Section: 7.1.2.1.1.8 FormalNumber: 07-01-01 Version: 1.2 Doc_Year: 2007 Doc_Month: January Doc_Day: 01 Page: 16 Title: Spec lacks definition regarding uniqueness of InstanceHandle_t Nature: Clarification Severity: Minor CODE: 3TMw8 B1: Report Issue Description: The spec defines the following: 7.1.2.1.1.8 get_instance_handle This operation returns the InstanceHandle_t that represents the Entity.
