Concept InfiniteRangeRunStorage

InfiniteRangeRunStorage

Description

An InfiniteRangeRunStorage is a RangeRunStorage with 2 additional Runs at the beginning and end that may be infinite.

pre_run_type
```
boost::result_of<boost::range_run_storage::op::pre_run(boost::add_reference<S>::type)>::type
```
The type of the pre-run, which comes before the runs in the runs property map. The pre-run may be infinite, but it is not required to be. pre_run_type must be a model of the Run concept.
post_run_type
```
boost::result_of<boost::range_run_storage::op::post_run(boost::add_reference<S>::type)>::type
```
The type of the post-run, which comes after the runs in the runs property map. The post-run may be infinite, but it is not required to be. post_run_type must be a model of the Run concept.

S: A type playing the role of infinite-range-run-storage-type in the InfiniteRangeRunStorage concept.
s: Object of type S

Name	Expression	Type	Semantics
Pre-Run	boost::range_run_storage::pre_run(s)	pre_run_type	Returns the pre-run.
Pre-Value	boost::range_run_storage::pre_value(s)	Convertible to value_type	Returns the value of the pre-run. If the pre-run is empty, the return value of `pre_value()` is undefined.
Post-Run	boost::range_run_storage::post_run(s)	post_run_type	Returns the post-run.
Post-Value	boost::range_run_storage::post_value(s)	Convertible to value_type	Returns the value of the post-run. If the post-run is empty, the return value of `post_value()` is undefined.
