\brief Asserts that the sequence is a Boost PP seq.
|

|
|
|

|
|
The macro checks that the sequence is a Boost PP seq.
|
||
|
|
If it is not a Boost PP seq, it forces a compiler error.
|
||
|
|
|
||
|
|
The macro normally checks for a Boost PP seq only in
|
||
|
|
debug mode. However an end-user can force the macro
|
||
|
|
to check or not check by defining the macro
|
||
|
|
BOOST_VMD_ASSERT_DATA to 1 or 0 respectively.
|

sequence = a possible Boost PP seq.

returns = Normally the macro returns nothing.

|
If the sequence is a Boost PP seq, nothing is
|
||
|
|
output.
|
||
|
|
|
||
|
|
For VC++, because there is no sure way of forcing
|
||
|
|
a compiler error from within a macro without producing
|
||
|
|
output, if the sequence is not a Boost PP seq the
|
||
|
|
macro forces a compiler error by outputting invalid C++.
|
||
|
|
|

For all other compilers a compiler error is forced
|

without producing output if the sequence is not a

Boost PP seq.
