Detailed Description
template<typename T, typename A = cache_aligned_allocator<T>>
class tbb::flow::interface7::buffer_node< T, A >
Forwards messages in arbitrary order.
Member Function Documentation
template<typename T, typename A = cache_aligned_allocator<T>>
|
inlinevirtual |
Adds a new successor.
Adds successor r to the list of successors; may forward tasks.
Implements tbb::flow::interface7::sender< T >.
template<typename T, typename A = cache_aligned_allocator<T>>
|
inlinevirtual |
Removes a successor.
Removes successor r from the list of successors. It also calls r.remove_predecessor(*this) to remove this node as a predecessor.
Implements tbb::flow::interface7::sender< T >.
template<typename T, typename A = cache_aligned_allocator<T>>
|
inlinevirtual |
Consumes a reserved item.
true = item is removed from sender and reservation removed
Reimplemented from tbb::flow::interface7::sender< T >.
template<typename T, typename A = cache_aligned_allocator<T>>
|
inlinevirtual |
Request an item from the buffer_node.
true = v contains the returned item
false = no item has been returned
Reimplemented from tbb::flow::interface7::sender< T >.
template<typename T, typename A = cache_aligned_allocator<T>>
|
inlinevirtual |
Release a reserved item.
true = item has been released and so remains in sender
Reimplemented from tbb::flow::interface7::sender< T >.
template<typename T, typename A = cache_aligned_allocator<T>>
|
inlinevirtual |
Reserves an item.
false = no item can be reserved
true = an item is reserved
Reimplemented from tbb::flow::interface7::sender< T >.
