NAME¶
std::match_results::match_results - std::match_results::match_results
Synopsis¶
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
