DDS12 — String sequence should be a parameter and not return value

Summary:
The string sequence parameter in the get_expression_parameters() method of the ContentFilteredTopic and MultiTopic and in the

get_query_parameters() method of the QueryCondition are all listed as the return value in both the PIM and PSM.
It is desirable for the string sequence to be used as a parameter for consistency and to allow for an error return.

Proposed Resolution:
The PIM and the PSM should have the string sequence as a parameter and the methods should return ReturnCode_t.

Proposed Revised Text:

Section 2.1.2.3.3 ContentFilteredTopic class; ContentFilteredTopic class table
Change row from:
get_expression_parameters string[]
To
get_expression_parameters ReturnCode_t
inout: expression_parameters string[]

Section 2.1.2.3.4 MultiTopic Class [optional]
Change row from:
get_expression_parameters string[]
To
get_expression_parameters ReturnCode_t
inout: expression_parameters string[]

Section 2.2.3 DCPS PSM : IDL

interface ContentFilteredTopic
Replace:
StringSeq get_expression_parameters();
With:
ReturnCode_t get_expression_parameters(inout StringSeq expression_parameters);

interface MultiTopic
Replace:
StringSeq get_expression_parameters();
With:
ReturnCode_t get_expression_parameters(inout StringSeq expression_parameters);
