Enclosing class:

MockCatalogReader

public static class MockCatalogReader.MustFilterMockTable
extends MockCatalogReader.MockTable
implements SemanticTable

Method Summary

Modifier and Type	Method	Description
List<Integer>	bypassFieldList()	Returns a list of column ordinals (0-based) of fields that defuse must-filter columns when filtered on.
static MockCatalogReader.MustFilterMockTable	create(MockCatalogReader catalogReader, MockCatalogReader.MockSchema schema, String name, boolean stream, double rowCount, @Nullable MockCatalogReader.ColumnResolver resolver, InitializerExpressionFactory initializerExpressionFactory, boolean temporal, Map<String,String> fieldFilters, List<Integer> bypassFieldList)	Creates a MustFilterMockTable.
@Nullable String	getFilter(int column)	Returns the filter expression for column if it is a must-filter column, or null if it is not a must-filter column.
boolean	mustFilter(int column)	Returns whether column must be filtered in any query that references this table.
