> Client javadoc suggestion:  add code examples about obtaining historical

>                 Key: HBASE-2004
>                 URL: https://issues.apache.org/jira/browse/HBASE-2004
>             Project: HBase
>          Issue Type: Improvement
>          Components: Client
>    Affects Versions: 0.20.1
>            Reporter: Doug Meil
>            Priority: Minor
>
> The implicit support HBase provides for versioning of values is very 
> powerful, but it's not all that obvious for application programmers to use it 
> to obtain the historical values.
> I would like to suggest adding some comments and sample code to the Result 
> class (org.apache.hadoop.hbase.client.Result) Javadoc.  I know this seems 
> sort of obvious to people that regularly use HBase, but I think that for new 
> folks having code examples available in Javadoc is helpful because it's "one 
> stop shopping" for documentation (i.e., as opposed to looking to an external 
> writeup).  Arguably, this type of example could also go in the HTable class 
> javadoc.
> e.g.,....
>     HTable table = new HTable(config, "mytable");
>     Scan scan = new Scan();   // no arguments indicates will scan all rows
>     scan.setMaxVersions( 5 );         // setting this to 1 only returns 
> current version
>     ResultScanner rs = table.getScanner(scan);
>     for (Iterator<Result> i = rs.iterator(); i.hasNext(); ) {
>       Result r = i.next();
>         // obtains current value from 'family:column'
>       byte b[] = r.getValue( Bytes.toBytes("family"), Bytes.toBytes("column") 
> );
>       KeyValue kv[] = r.raw();
>       for (int j = 0; j < kv.length; j++) {
>               
>                byte bv[] = kv[j].getValue();
>               // this loop returns both current and historical values
>                byte bc[] = kv[j].getColumn();
>                // returns 'family:column'
>          }
>    }    
>
