Examples of org.apache.hadoop.hbase.filter.SkipFilter

org.apache.hadoop.hbase.filter.SkipFilter
A wrapper filter that filters an entire row if any of the KeyValue checks do not pass.
For example, if all columns in a row represent weights of different things, with the values being the actual weights, and we want to filter out the entire row if any of its weights are zero. In this case, we want to prevent rows from being emitted if a single key is filtered. Combine this filter with a {@link ValueFilter}:
```
 scan.setFilter(new SkipFilter(new ValueFilter(CompareOp.EQUAL, new BinaryComparator(Bytes.toBytes(0))));  Any row which contained a column whose value was 0 will be filtered out. Without this filter, the other non-zero valued columns in the row would still be emitted.
```
