stack updated HBASE-6142:
-------------------------
Tags: noob (was: noo)
Labels: noob (was: )
Tagging as noob. Would be grand if an angel from heaven would write little
unit tests to verify which way the filter blows and fix the javadoc accordingly
(Lars George, if we read that book of yours, would it answer the questions Joep
raises? IIRC, its good on filters?)
> Javadoc in some Filters ambiguous
> ---------------------------------

> Key: HBASE-6142
> URL: https://issues.apache.org/jira/browse/HBASE-6142
> Project: HBase
> Issue Type: Bug
> Components: documentation
> Affects Versions: 0.92.2, 0.96.0, 0.94.1
> Reporter: Joep Rottinghuis
> Priority: Minor
> Labels: noob
>
> The javadoc on some of the filter is somewhat confusing.
> The main Filter interface has methods that behave like a sieve; when
> filterRowKey returns true, that means that the row is filtered _out_ (not
> included).
> Many of the Filter implementations work the other way around. When the
> condition is met the value passes (ie, the row is returned).
> Most Filters make it clear when a values passes (passing through the filter
> meaning the values are returned from the scan).
> Some are less clear in light of how the Filter interface works:
> WhileMatchFilter and SingleColumnValueFilter are examples.
