Revision 1.3, Sun Dec 3 12:40:40 2000 UTC (23 years, 7 months ago) by ohara
Branch: MAIN
CVS Tags: R_1_3_1-2, RELEASE_1_3_1_13b, RELEASE_1_2_3_12, RELEASE_1_2_3, RELEASE_1_2_2_KNOPPIX_b, RELEASE_1_2_2_KNOPPIX, RELEASE_1_2_2, RELEASE_1_2_1, KNOPPIX_2006, HEAD, DEB_REL_1_2_3-9
Changes since 1.2: +7 -1 lines 

allowQ() methods are added.

In order to prevent a MathcapViolation,
we must inspect a CMObject by allowQ() before sending it to OXstream.
