org.apache.lucene.gdata.search.analysis.ContentStrategy

Creating Indexable document requires processing of incoming entities as GData Entries. Entries in the GData protocol might have very different structures and content. They all have on thing in common as they are atom xml format. To retrieve the configured elements of the atom format and process the actual content might differ from element to element.

Each predefined ContentStrategy can be used to retrieve certain content from the defined element. Which element to process is defined using a XPath expression in the gdata-config.xml file.

ContentStrategy implementation should not be accessed directly. To get a ContentStrategy for a specific {@link org.apache.lucene.gdata.search.config.IndexSchemaField.ContentType}use the {@link ContentStrategy#getFieldStrategy} factory method. This methodexpects a IndexSchemaField instance with a set ContentType. The return value is a new ContentStrategy instance for the defined ContentType.
