- The <b>BOOST_PP_SEQ_FOR_EACH_PRODUCT</b> macro repeats a macro for each
- cartesian product of several <i>seqs</i>.
- </div>
- <h4>
- Usage
- </h4>
- <div class="code">
- <b>BOOST_PP_SEQ_FOR_EACH_PRODUCT</b>(<i>macro</i>, <i>seqs</i>)
- </div>
- <h4>
- Arguments
- </h4>
- <dl>
- <dt>macro</dt>
- <dd>
- The binary macro of the form <i>macro</i>(<i>r</i>, <i>product</i>). This
- macro is expanded by <b>BOOST_PP_FOR_EACH_PRODUCT</b> with each cartesian
- product in <i>seqs</i>. It is expanded with the next available <b>BOOST_PP_FOR</b>
- repetition and a <i>seq</i> containing a cartesian product.
- </dd>
- <dt>seqs</dt>
- <dd>
- A <i>seq</i> of <i>seqs</i> from which cartesian products are obtained.
- </dd>
- </dl>
- <h4>
- Remarks
- </h4>
- <div>
- This macro is a repetition construct. If two <i>seqs</i> are (<i>a</i>)(<i>b</i>)(<i>c</i>)
- and (<i>x</i>)(<i>y</i>)(<i>z</i>), this macro will produce the following
- sequence:
- <div>
- <i>macro</i>(<i>r</i>, (<i>a</i>)(<i>x</i>)) <i>macro</i>(<i>r</i>, (<i>a</i>)(<i>y</i>))
- <i>macro</i>(<i>r</i>, (<i>a</i>)(<i>z</i>)) \
- <br>
- <i>macro</i>(<i>r</i>, (<i>b</i>)(<i>x</i>)) <i>macro</i>(<i>r</i>, (<i>b</i>)(<i>y</i>))
- <i>macro</i>(<i>r</i>, (<i>b</i>)(<i>z</i>)) \
- <br>
- <i>macro</i>(<i>r</i>, (<i>c</i>)(<i>x</i>)) <i>macro</i>(<i>r</i>, (<i>c</i>)(<i>y</i>))
- <i>macro</i>(<i>r</i>, (<i>c</i>)(<i>z</i>))
- </div>
- </div>
- <div>
- For maximum efficiency, use <b>BOOST_PP_SEQ_FOR_EACH_PRODUCT_R</b>.
