| 5 // The basic usage of the Filter interface is described in the comment at | |
| 6 // the beginning of filter.h. If Filter::Factory is passed a vector of | |
| 7 // size greater than 1, that interface is implemented by a series of filters | |
| 8 // connected in a chain. In such a case the first filter | |
| 9 // in the chain proxies calls to ReadData() so that its return values | |
| 10 // apply to the entire chain. | |
| 11 // | |
| 12 // In a filter chain, the data flows from first filter (held by the | |
| 13 // caller) down the chain. When ReadData() is called on any filter | |
| 14 // except for the last filter, it proxies the call down the chain, | |
| 15 // filling in the input buffers of subsequent filters if needed (== | |
| 16 // that filter's last_status() value is FILTER_NEED_MORE_DATA) and | |
| 17 // available (== the current filter has data it can output). The last | |
| 18 // Filter will then output data if possible, and return | |
| 19 // FILTER_NEED_MORE_DATA if not. Because the indirection pushes | |
| 20 // data along the filter chain at each level if it's available and the | |
| 21 // next filter needs it, a return value of FILTER_NEED_MORE_DATA from the | |
| 22 // final filter will apply to the entire chain. | |
