Detailed Description

template<typename T>
class sf::ThreadLocalPtr< T >

Pointer to a thread-local variable.

sf::ThreadLocalPtr is a type-safe wrapper for storing pointers to thread-local variables.

A thread-local variable holds a different value for each different thread, unlike normal variables that are shared.

Its usage is completely transparent, so that it is similar to manipulating the raw pointer directly (like any smart pointer).

Usage example:

MyClass object1;
MyClass object2;
sf::ThreadLocalPtr<MyClass> objectPtr;
 
void thread1()
{
    objectPtr = &object1; // doesn't impact thread2
    ...
}
 
void thread2()
{
    objectPtr = &object2; // doesn't impact thread1
    ...
}
 
int main()
{
    // Create and launch the two threads
    sf::Thread t1(&thread1);
    sf::Thread t2(&thread2);
    t1.launch();
    t2.launch();
 
    return 0;
}

ThreadLocalPtr is designed for internal use; however you can use it if you feel like it fits well your implementation.

Constructor & Destructor Documentation

ThreadLocalPtr()

template<typename T >

sf::ThreadLocalPtr< T >::ThreadLocalPtr

(

T *

value = NULL

)

Default constructor.

Parameters

value

Optional value to initialize the variable

Member Function Documentation

operator T*()

template<typename T >

sf::ThreadLocalPtr< T >::operator T*

(

)

const

Conversion operator to implicitly convert the pointer to its raw pointer type (T*)

Returns

Pointer to the actual object

operator*()

template<typename T >

T & sf::ThreadLocalPtr< T >::operator*

(

)

const

Overload of unary operator *.

Like raw pointers, applying the * operator returns a reference to the pointed-to object.

Returns

Reference to the thread-local variable

operator->()

template<typename T >

T * sf::ThreadLocalPtr< T >::operator->

(

)

const

Overload of operator ->

Similarly to raw pointers, applying the -> operator returns the pointed-to object.

Returns

Pointer to the thread-local variable

operator=() [1/2]

template<typename T >

ThreadLocalPtr< T > & sf::ThreadLocalPtr< T >::operator=

(

const ThreadLocalPtr< T > &

right

)

Assignment operator for a ThreadLocalPtr parameter.

Parameters

right

ThreadLocalPtr to assign

Returns

Reference to self

operator=() [2/2]

template<typename T >

ThreadLocalPtr< T > & sf::ThreadLocalPtr< T >::operator=

(

T *

value

)

Assignment operator for a raw pointer parameter.

Parameters

value

Pointer to assign

Returns

Reference to self
