Package com.norconex.importer.handler.transformer.impl

Class NoContentTransformer

  • All Implemented Interfaces:
    IXMLConfigurable, IImporterHandler, IDocumentTransformer
    public class NoContentTransformer
extends AbstractDocumentTransformer
implements IXMLConfigurable

    Get rid of the content stream and optionally store it as text into a metadata field instead.

    Storing content in an existing field

    If a toField with the same name already exists for a document, the value will be added to the end of the existing value list. It is possible to change this default behavior by supplying a PropertySetter.

    This class can be used both as a pre-parsing or post-parsing handler. To store the content in a field, make sure pre-parsing is of a text content-types.

    XML configuration usage:

    
<handler
    class="com.norconex.importer.handler.transformer.impl.NoContentTransformer"
    toField="(Optionally store content into a field.)">
  <!-- 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="NoContentTransformer"/>

    The above example removes the content of all documents (leaving you with metadata only).
