Detailed Description

TSync provides a system-independent interface to build classes that act like monitors, i.e., classes in which only one member can execute on a particular instance at any one time.

TSync uses TCriticalSection, so it is portable to all platforms that TCriticalSection has been ported to.

Example

class ThreadSafe : private TSync
{
  public:
    void f();
    void g();
  private:
    int i;
};
 
void ThreadSafe::f()
{
  TLock lock(this);
  if (i == 2)
    i = 3;
}
 
void ThreadSafe::g()
{
  TLock lock(this);
  if (i == 3)
    i = 2;
}

Constructor & Destructor Documentation

TSync() [1/2]

owl::TSync::TSync ( )

inlineprotected

Default constructor.

Definition at line 1299 of file thread.h.

TSync() [2/2]

owl::TSync::TSync ( const TSync & )

inlineprotected

Copy constructor does not copy the TCriticalSection object, since the new object is not being used in any of its own member functions.

This means that the new object must start in an unlocked state.

Definition at line 1309 of file thread.h.

Member Function Documentation

operator=()

const TSync & owl::TSync::operator= ( const TSync & )

inlineprotected

Does not copy the TCriticalSection object, since the new object is not being used in any of its own member functions.

This means that the new object must start in an unlocked state.
