@Deprecated
public class EmptyMetadataFilter
extends AbstractDocumentFilter

Deprecated.

Accepts or rejects a document based on whether any of the specified metadata fields are empty or not. Any control characters (char <= 32) are removed before evaluating if a field is empty or not.

XML configuration usage:

<handler
    class="com.norconex.importer.handler.filter.impl.EmptyMetadataFilter"
    onMatch="[include|exclude]"
    fields="(coma separated list of fields to match)">
  <!-- multiple "restrictTo" tags allowed (only one needs to match) -->
  <restrictTo>
    <fieldMatcher>(field-matching expression)</fieldMatcher>
    <valueMatcher>(value-matching expression)</valueMatcher>
  </restrictTo>
</handler>

XML usage example:

<handler
    class="EmptyMetadataFilter"
    onMatch="exclude"
    fields="title,dc:title"/>

The above example excludes documents without titles.
