Revision: 1.14, Tue May 24 19:26:33 2005 UTC (19 years, 1 month ago) by karl Branch: MAIN Changes since 1.13: +900 -1262 lines BUG#: 2653 TITLE: SMI-S scoped property not implemented in Pegasus WQL DESCRIPTION: Implemented in the same manner as the WQL ISA, with a flag that allows it only to be compiled if the compile flag PEGASUS_SNIA_EXTENSIONS is set. This means that nobody but SNIA users need have these extensions enabled. Note that these are enabled only in the parser, there is no evaluation support, etc. Also the ParserCLI was expanded to provide negative tests so that the non-existence of these functions in normal compile mode is also tested. |
