| std::function< _Res(_ArgTypes...)>::function | ( | const function< _Res(_ArgTypes...)> & | __x | ) |
Function copy constructor.
| __x | A function object with identical call signature. |
bool(*this) == bool(__x)The newly-created function contains a copy of the target of __x (if it has one).
Definition at line 2398 of file functional.

Function move constructor.
| __x | A function object rvalue with identical call signature. |
The newly-created function contains the target of __x (if it has one).
Definition at line 2194 of file functional.
| std::function< _Res(_ArgTypes...)>::function | ( | _Functor | __f | ) |
Builds a function that targets a copy of the incoming function object.
| __f | A function object that is callable with parameters of type T1, T2, ..., TN and returns a value convertible to Res. |
The newly-created function object will target a copy of __f. If __f is reference_wrapper<F>, then this function object will contain a reference to the function object __f.get(). If __f is a NULL function pointer or NULL pointer-to-member, the newly-created object will be empty.
If __f is a non-NULL function pointer or an object of type reference_wrapper<F>, this function will not throw.
Definition at line 2412 of file functional.

Determine if the function wrapper has a target.
true when this function object contains a target, or false when it is empty.This function will not throw an exception.

| _Res std::function< _Res(_ArgTypes...)>::operator() | ( | _ArgTypes... | __args | ) | const |
Invokes the function targeted by *this.

The function call operator invokes the target function object stored by this.
Definition at line 2428 of file functional.
|
inline |
Function assignment operator.
| __x | A function with identical call signature. |
*this The target of __x is copied to *this. If __x has no target, then *this will be empty.
If __x targets a function pointer or a reference to a function object, then this operation will not throw an exception.

inline |
Function move-assignment operator.
| __x | A function rvalue with identical call signature. |
*this The target of __x is moved to *this. If __x has no target, then *this will be empty.
If __x targets a function pointer or a reference to a function object, then this operation will not throw an exception.

inline |
Function assignment to zero.
!(bool)*this *this The target of *this is deallocated, leaving it empty.
Definition at line 2266 of file functional.
|
inline |
Function assignment to a new target.
| __f | A function object that is callable with parameters of type T1, T2, ..., TN and returns a value convertible to Res. |
*this This function object wrapper will target a copy of __f. If __f is reference_wrapper<F>, then this function object will contain a reference to the function object __f.get(). If __f is a NULL function pointer or NULL pointer-to-member, this object will be empty.
If __f is a non-NULL function pointer or an object of type reference_wrapper<F>, this function will not throw.

References std::swap().
|
inline |
Swap the targets of two function objects.
| __x | A function with identical call signature. |
Swap the targets of this function object and __f. This function will not throw an exception.
