23/** \def BOOST_VMD_ASSERT_IS_ARRAY(sequence)
24
25 \brief Asserts that the sequence is a Boost PP array.
26
27 The macro checks that the sequence is a Boost PP array.
28 If it is not a Boost PP array, it forces a compiler error.
29
30 The macro normally checks for a Boost PP array only in
31 debug mode. However an end-user can force the macro
32 to check or not check by defining the macro
33 BOOST_VMD_ASSERT_DATA to 1 or 0 respectively.
34
35 sequence = a possible Boost PP array.
36
37 returns = Normally the macro returns nothing.
38
39 If the sequence is a Boost PP array, nothing is
40 output.
41
42 For VC++, because there is no sure way of forcing
43 a compiler error from within a macro without producing
44 output, if the sequence is not a Boost PP array the
45 macro forces a compiler error by outputting invalid C++.
46
47 For all other compilers a compiler error is forced
48 without producing output if the sequence is not a
49 Boost PP array.
