PHP SMWQuery::setOffset方法代码示例

 /**
  * Parse a query string given in SMW's query language to create
  * an SMWQuery. Parameters are given as key-value-pairs in the
  * given array. The parameter $context defines in what context the
  * query is used, which affects ceretain general settings.
  * An object of type SMWQuery is returned.
  *
  * The format string is used to specify the output format if already
  * known. Otherwise it will be determined from the parameters when
  * needed. This parameter is just for optimisation in a common case.
  *
  * @param string $queryString
  * @param array $params These need to be the result of a list fed to getProcessedParams
  * @param $context
  * @param string $format
  * @param array $extraPrintouts
  *
  * @return SMWQuery
