## Detailed Description

### template<typename Output>
class tbb::flow::interface6::source_node< Output >

An executable node that acts as a source, i.e. it has no predecessors.

## Member Function Documentation

template<typename Output>

bool tbb::flow::interface6::source_node< Output >::try_release | ( |  | ) | `[inline, virtual]`

Release a reserved item.

true = item has been released and so remains in sender, dest must request or reserve future items

Reimplemented from tbb::flow::interface6::sender< Output >.
