Constructor Detail

### LinearQuery

    public LinearQuery()

  Creates a query

  A super.getLog() must be set and then this query must be setUp.

Method Detail

### setUp

    public void setUp(SearchLocations sLocs,
                      java.lang.String[] queryTerms,
                      java.lang.String[] fields,
                      int[] connectors,
                      int operator)
               throws SDXException

  Constructs a linear query.

  Parameters:
    `sLocs` - The SearchLocations object (indices to be searched).
    `queryTerms` - The query terms.
    `connectors` - The operators.
    `fields` - The field names to search.
    `operator` - The operator for the query (ie AND or OR).
  Throws:
    `SDXException`

### toSAX

    public void toSAX(org.xml.sax.ContentHandler hdl)
               throws org.xml.sax.SAXException

  Returns a SAX representation of this acceptRequest.

  Specified by:
    `toSAX` in interface `org.apache.excalibur.xml.sax.XMLizable`
  Specified by:
    `toSAX` in class `AbstractQuery`
  Parameters:
    `hdl` - The ContentHandler to feed with events.
