Class core.sync.barrier.Barrier
This class represents a barrier across which threads may only travel in groups of a specific size.
class Barrier
;
Constructors
Name | Description |
---|---|
this
(limit)
|
Initializes a barrier object which releases threads in groups of limit in size. |
Methods
Name | Description |
---|---|
wait
()
|
Wait for the pre-determined number of threads and then proceed. |
factory
(classname)
|
Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor. |
opCmp
(o)
|
Compare with another Object obj. |
opEquals
(o)
|
Test whether this is equal to o .
The default implementation only compares by identity (using the is operator).
Generally, overrides and overloads for opEquals should attempt to compare objects by their contents.
A class will most likely want to add an overload that takes your specific type as the argument
and does the content comparison. Then you can override this and forward it to your specific
typed overload with a cast. Remember to check for null on the typed overload.
|
toHash
()
|
Compute hash function for Object. |
toString
()
|
Convert Object to a human readable string. |
Example
import core .thread;
int numThreads = 10;
auto barrier = new Barrier( numThreads );
auto synInfo = new Object;
int numReady = 0;
int numPassed = 0;
void threadFn()
{
synchronized( synInfo )
{
++numReady;
}
barrier .wait();
synchronized( synInfo )
{
++numPassed;
}
}
auto group = new ThreadGroup;
for ( int i = 0; i < numThreads; ++i )
{
group .create( &threadFn );
}
group .joinAll();
assert( numReady == numThreads && numPassed == numThreads );
