| |
| This class is <b>NOT THREAD SAFE</b>.<p> |
| |
| Convenience methods are available that return various <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Map.html?is-external=true" title="class or interface in java.util"><code>Map</code></a> |
| structures and values directly.<p> |
| |
| To get a complete mapping of all cells in the Result, which can include |
| multiple families and multiple versions, use <a href="../../../../../org/apache/hadoop/hbase/client/Result.html#getMap--"><code>getMap()</code></a>.<p> |
| |
| To get a mapping of each family to its columns (qualifiers and values), |
| including only the latest version of each, use <a href="../../../../../org/apache/hadoop/hbase/client/Result.html#getNoVersionMap--"><code>getNoVersionMap()</code></a>. |
| |
| To get a mapping of qualifiers to latest values for an individual family use |
| <a href="../../../../../org/apache/hadoop/hbase/client/Result.html#getFamilyMap-byte:A-"><code>getFamilyMap(byte[])</code></a>.<p> |
| |
| To get the latest value for a specific family and qualifier use |
| <a href="../../../../../org/apache/hadoop/hbase/client/Result.html#getValue-byte:A-byte:A-"><code>getValue(byte[], byte[])</code></a>. |
| |
| A Result is backed by an array of <a href="../../../../../org/apache/hadoop/hbase/Cell.html" title="interface in org.apache.hadoop.hbase"><code>Cell</code></a> objects, each representing |
| an HBase cell defined by the row, family, qualifier, timestamp, and value.<p> |
| |
| The underlying <a href="../../../../../org/apache/hadoop/hbase/Cell.html" title="interface in org.apache.hadoop.hbase"><code>Cell</code></a> objects can be accessed through the method <a href="../../../../../org/apache/hadoop/hbase/client/Result.html#listCells--"><code>listCells()</code></a>. |
| This will create a List from the internal Cell []. Better is to exploit the fact that |
| a new Result instance is a primed <a href="../../../../../org/apache/hadoop/hbase/CellScanner.html" title="interface in org.apache.hadoop.hbase"><code>CellScanner</code></a>; just call <a href="../../../../../org/apache/hadoop/hbase/client/Result.html#advance--"><code>advance()</code></a> and |
| <a href="../../../../../org/apache/hadoop/hbase/client/Result.html#current--"><code>current()</code></a> to iterate over Cells as you would any <a href="../../../../../org/apache/hadoop/hbase/CellScanner.html" title="interface in org.apache.hadoop.hbase"><code>CellScanner</code></a>. |
| Call <a href="../../../../../org/apache/hadoop/hbase/client/Result.html#cellScanner--"><code>cellScanner()</code></a> to reset should you need to iterate the same Result over again |
| (<a href="../../../../../org/apache/hadoop/hbase/CellScanner.html" title="interface in org.apache.hadoop.hbase"><code>CellScanner</code></a>s are one-shot). |
| |
| If you need to overwrite a Result with another Result instance -- as in the old 'mapred' |
| RecordReader next invocations -- then create an empty Result with the null constructor and |
| in then use <a href="../../../../../org/apache/hadoop/hbase/client/Result.html#copyFrom-org.apache.hadoop.hbase.client.Result-"><code>copyFrom(Result)</code></a></div> |
