Class RowFilter

java.lang.Object
  com.nhncorp.neptune.client.RowFilter

All Implemented Interfaces:

com.nhncorp.neptune.common.io.NWritable

public class RowFilter
extends java.lang.Object
implements com.nhncorp.neptune.common.io.NWritable

RowFilter and CellFilter are normally used to get or scan for complex search condition

 NTable ntable = NTable.openTable(...);
 RowFilter rowFilter = new RowFilter(new Row.Key("rk1"), OP_LIKE);
 CellFilter cellFilter = new CellFilter("Column1");
 cellFilter.setStartTimestamp(Long.MIN_VALUE);
 cellFilter.setEndTimestamp(Long.MAX_VALUE);
 rowFilter.addCellFilter(cellFilter);

 Row[] rows = ntable.gets(rowFilter);
