+<div class="block">An interface for iterating through a sequence of cells. Similar
to Java's Iterator, but without
+ the hasNext() or remove() methods. The hasNext() method is problematic because it may require
+ actually loading the next object, which in turn requires storing the previous object somewhere.
+
+ <p>The core data block decoder should be as fast as possible, so we push the complexity
and
+ performance expense of concurrently tracking multiple cells to layers above the CellScanner.
+ <p>
+ The <a href="../../../../org/apache/hadoop/hbase/CellScanner.html#current--"><code>current()</code></a>
method will return a reference to a Cell implementation. This reference
+ may or may not point to a reusable cell implementation, so users of the CellScanner should
not,
+ for example, accumulate a List of Cells. All of the references may point to the same object,
+ which would be the latest state of the underlying Cell. In short, the Cell is mutable.
+ </p>
+ Typical usage:
+
+ <pre>
+ while (scanner.advance()) {
+   Cell cell = scanner.current();
+   // do something
+ }
+ </pre>
+ <p>Often used reading <a href="../../../../org/apache/hadoop/hbase/Cell.html" title="org.apache.hadoop.hbase中的接口"><code>Cell</code></a>s
