BOOST_MPL_LIMIT_UNROLLING

Synopsis

#if !defined([BOOST\_MPL\_LIMIT\_UNROLLING](./limit-unrolling.html))
# define[BOOST\_MPL\_LIMIT\_UNROLLING](./limit-unrolling.html)\_implementation-defined integral constant_\
/**/
#endif

Description

BOOST_MPL_LIMIT_UNROLLING is an overridable configuration macro regulating the unrolling depth of the library's iteration algorithms. In this implementation of the library, BOOST_MPL_LIMIT_UNROLLING has a default value of 4. To override the default, define BOOST_MPL_LIMIT_UNROLLING to the desired value before including any library header. [Note: Overriding will take effect only if the library is configured not to use preprocessed headers. See BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS for more information. — end note]

Example

Except for overall library performace, overriding the BOOST_MPL_LIMIT_UNROLLING's default value has no user-observable effects.
