Java synchronized method:
class Foo
{
public synchronized void bar() { /* code */ }
}
Boost.Threads synchronized method:
class Foo
{
public:
void bar() { boost::mutex::scoped_lock lock(m_mutex); /* code */ }
private:
boost::mutex m_mutex;
};
Java synchronized block:
class Foo
{
public void bar() {
synchronized (this) {
/* code */
}
}
}
Boost.Threads synchronized block:
class Foo
{
public:
void bar() {
{
boost::mutex::scoped_lock lock(m_mutex);
/* code */
}
}
private:
boost::mutex m_mutex;
};

Yes.
