DESCRIPTION¶
This class implements filtering of streams.
ATTRIBUTES¶
- filter
- The code reference to apply to each block.
The block is passed to the filter both in $_ and as the first argument.
The return value should be an array reference. If no true value is returned
the output stream does not end, but instead an empty block is
substituted (the parent stream controls when the stream is depleted).
- stream
- The stream to be filtered
METHODS¶
- is_done
- loaded
- Delegated to "stream"
- next
- Calls "next" on "stream" and applies
"filter" if a block was returned.
