---------------------------------------------
Also, you should override EntityProcessorBase#destroy and close the reader
object in it.

> I have finished a new DIH EntityProcessor. It is designed around the idea
> that whatever demon is used to maintain your content store it is likely to
> drop a report or log file explaining what has changed within your content
> store. I wish to use this report file to control the indexing of the new or
> changed content and the removal of old content. The report files, perhaps
> from un-tar or un-zip, are likely to reference jpegs and directory stubs
> which need to be ignored. I assumed a file based content repository but this
> should be expanded to handle URI's as well
> I feel that the current FileListEntityProcessor is poorly named. It should be
> called the dirWalkEntityProcessor or dirCrawlEntityProcessor or such. And
> this new EntityProcessor should have the name FileListEntityProcessor.
> However what is done is done. I then came up with manifestEnityProcessor
> which I thought suited, manifest files are all over the content sets I deal
> with and the dictionary definition seemed close enough ("ships manifest").
> However how about ChangeListEntityProcessor
> {code}
> <entity name="jc"
> processor="ManifestEntityProcessor"
> baseDir="/Volumes/Techmore/ts/aaa/schema/data"
> rootEntity="false"
> dataSource="null"
> allowRegex="^.*\.xml$"
> blockRegex="usc2009"
> manifestFileName="/Volumes/ts/man-find.txt"
> docAddRegex=".*"

> The new entity fields are as follows.
>
> *manifestFileName* is the required location of the manifest file. If this
> value is relative, it assumed to be relative to baseDir.
> *allowRegex* is an optional attribute that if present discards any line
> which does not match the regExp
>
> *blockRegex* is an optional attribute that is applied after any allowRegex
> and discards any line which matches the regExp
> *docAddRegex* is a required regex to identify lines which when matched
> should cause docs to be added to the index. As well as matching the line it
> should also return the portion of the line which contains the filepath as
> group(1)
> *docDeleteRegex* is an optional value of a regex to identify documents
> which when matched should be deleted from the index. As well as matching the
> line it should also return the portion of the line which contains the
> filepath as group(1) **PLANNED**
