<div class="textblock"><h3>template&lt;typename T, class A = cache_aligned_allocator&lt;T&gt;&gt;<br/>
class tbb::concurrent_bounded_queue&lt; T, A &gt;</h3>

<p>A high-performance thread-safe blocking concurrent bounded queue. </p>
<p>This is the pre-PPL TBB concurrent queue which supports boundedness and blocking semantics. Note that method names agree with the PPL-style concurrent queue. Multiple threads may each push and pop concurrently. Assignment construction is not allowed. </p>
