List of nextRows() Examples

Examples of nextRows()

org.hbase.async.Scanner.nextRows()
Scans a number of rows. Calling this method is equivalent to:
```
 this. {@link #setMaxNumRows setMaxNumRows}(nrows); this. {@link #nextRows() nextRows}(); 
```
@param nrows The maximum number of rows to retrieve. @return A deferred list of rows. @see #setMaxNumRows @see #nextRows()
