public class DataSourceFilter
extends ArbitraryLQLASTFilter

LQL 2.3-compliant QueryFilter that adds an arbitrary LQL expression to the DataSourceFilter of the current QueryState. This QueryFilter stacks with all other QueryFilters; it does not replace any other existing data source filters. Note that the data source filter is applied at the same layer as old style record filters/security filters, which is prior to the execution of refinements. This means that ALLBASERECORDS will be limited by this filter, as will text-search autocorrections. All the string based methods for this return a JSON representation of the filter, not the human readable syntax like you'd expect. For the human readable one, @see StringSelectionFilter
