## Detailed Description

pure virtual abstract base class for output filters, i.e.

intermediate nodes of a filter chain in an output stream.

## Member Function Documentation

## ◆ append()

virtual void DcmOutputFilter::append | ( | DcmConsumer & | consumer | ) |
| pure virtual

determines the consumer to which the filter is supposed to write it's output.

Once a consumer for the output filter has been defined, it cannot be changed anymore during the lifetime of the object.

Parameters

  consumer | reference to consumer, must not be circular chain

Implemented in DcmZLibOutputFilter.
