SingleColumnValueFilter
Hi there,
Can I set multiple SingleColumnValueFilter for a qualifier like following
sample codes?
The scan result is nothing, so I think whether the filters can combine
these filter with "OR" instead of " AND".
Any ideas?
//=======================================================================================
Scan s = new Scan();
FilterList fl = new FilterList();
SingleColumnValueFilter scv1 = new SingleColumnValueFilter
(Bytes.toBytes("cf"),
Bytes.toBytes("q1"),
CompareFilter.CompareOp.EQUAL,
new RegexStringComparator("^AA")) ;
SingleColumnValueFilter scv2 = new SingleColumnValueFilter
(Bytes.toBytes("cf"),
Bytes.toBytes("q1"),
CompareFilter.CompareOp.EQUAL,
new RegexStringComparator("^BB")) ;
SingleColumnValueFilter scv3 = new SingleColumnValueFilter
(Bytes.toBytes("cf"),
Bytes.toBytes("q1"),
CompareFilter.CompareOp.EQUAL,
new RegexStringComparator("^CC")) ;
fl.addFilter(scv1);
fl.addFilter(scv2);
fl.addFilter(scv3);
s.setFilter(fl);
