std::match_results<BidirIt,Alloc>::match_results
match_results() : match_results(Allocator()) { } |
(1) | (since C++11) |
explicit match_results( const Allocator& a ); |
(2) | (since C++11) |
match_results( const match_results& rhs ); |
(3) | (since C++11) |
match_results( match_results&& rhs ) noexcept; |
(4) | (since C++11) |
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) Move constructor. Constructs a match result with the contents of
rhs
using move semantics.
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_result to use as source to initialize the match_result with |
Exceptions
1-3) May throw implementation-defined exceptions.
