Detailed Description

Abstract base class that represents a node in a parse tree underlying a filter_t.

These nodes are always heap-allocated and can be shared by filter_t objects.

ref_count

tbb::atomic<intptr_t> tbb::interface6::internal::filter_node::ref_count

private

Count must be atomic because it is hidden state for user, but might be shared by threads.
