1,2)
Constructs a match result with no established result state.
1)
The default constructor.
2)
Constructs the match result using a copy of
a
as the allocator.
3-6)
Constructs a match result from
rhs
.
3)
The copy constructor.
4)
Constructs the match result using a copy of
a
as the allocator.
5)
The move constructor. When the construction finishes,
rhs
is in a valid but unspecified state.
6)
Constructs the match result using a copy of
a
as the allocator. When the construction finishes,
rhs
is in a valid but unspecified state.
Given the value of
rhs
before the construction as
m
and any integer in
[
0
,
m.
size
(
)
)
as
n
, when the construction finishes, the following member functions should return the specified values:
| Member function | Value |
|---|---|
ready()
|
m. ready ( ) |
size()
|
m. size ( ) |
str(n)
|
m. str ( n ) |
prefix()
|
m. prefix ( ) |
suffix()
|
m. suffix ( ) |
operator[](n)
|
m [ n ] |
length(n)
|
m. length ( n ) |
position(n)
|
m. position ( n ) |
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

Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
|---|---|---|---|
| LWG 2191 | C++11 | n could be negative in the postconditions of overloads (3-6) | can only be non-negative |
| LWG 2195 | C++11 | the constructors required by AllocatorAwareContainer were missing | added |
| P0935R0 | C++11 | default constructor was explicit | made implicit |
