William Slacum created ACCUMULO-675:
---------------------------------------
Summary: WrappingIterator's seenSeek should be protected
Key: ACCUMULO-675
URL: https://issues.apache.org/jira/browse/ACCUMULO-675
Project: Accumulo
Issue Type: Bug
Components: tserver
Affects Versions: 1.5.0, 1.4.1, 1.5.0-SNAPSHOT, 1.4.0
Environment: OSX, Linux
Reporter: William Slacum
Assignee: William Slacum
Priority: Trivial
Fix For: 1.5.0-SNAPSHOT
In 1.3, the WrappingIterator was pretty much some boilerplate code. In 1.4 on,
a package private boolean called seenSeek was added to help enforce the
iterator contract.
This causes some issues with iterators written for 1.3 and before, because the
seenSeek property can't be set by an iterator outside of the core.iterators
package, which is locked down. This means that sub iterators must always
delegate up to the WrappingIterator's seek() method, even if implementors want
to completely override seek().
I would like to provide more documentation on the WrappingIterator and make the
seenSeek property protected so implementors don't need conditional logic to
make the call to super.seek().
