1) Default constructor. Constructs a match result with no established result state (
ready() != true).
2) Constructs a match result with no established result state (
ready() != true) using a copy of a as the allocator.
3) Copy constructor. Constructs a match result with a copy of
rhs.
4) Constructs a match result with a copy of
rhs, and uses a copy of a as the allocator.
5) Move constructor. Constructs a match result with the contents of
rhs using move semantics. rhs is in valid, but unspecified state after the call.
6) Constructs a match result with the contents of
rhs using move semantics, and uses a copy of a as the allocator. rhs is in valid, but unspecified state after the call.
Parameters
| a | - | allocator to use for all memory allocations of this container |
| rhs | - | another match_results to use as source to initialize the match_results with |
Exceptions
1-4) May throw implementation-defined exceptions.
6) Throws nothing if
a == rhs.get_allocator() is true.
