Class Summary

Class	Description
AggGen	This class is used to create "lost" and "collapsed" aggregate table creation sql (creates the rdbms table and inserts into it from the base fact table).
AggGenTest	Test if lookup columns are there after loading them in AggGen#addCollapsedColumn(...).
AggStar	Aggregate table version of a RolapStar for a fact table.
AggTableManager	Manages aggregate tables.
AggTableTestCase	This abstract class can be used as the basis for writing aggregate table test in the "testsrc/main/mondrian/rolap/aggmatcher" directory.
BUG_1541077	Testcase for MONDRIAN-214 (formerly SourceForge bug 1541077) and a couple of other aggregate table ExplicitRecognizer conditions.
Checkin_7634	Checkin 7634 attempted to correct a problem demonstrated by this junit.
Checkin_7641	Checkin 7641 attempted to correct a problem demonstrated by this junit.
DefaultDef	This is the XML model for defining default aggregate table recognition and level/measure mapping.
DefaultDef.AggRule	A RolapConnection uses one AggRule.
DefaultDef.AggRules	The set of "named" rules for matching aggregate tables.
DefaultDef.Base	Base is the base class for all of the elements.
DefaultDef.CaseMatcher	This is a base class for all elements that can match strings where the case of the string is important.
DefaultDef.FactCountMatch	This is used to identify the "fact_count" column in an aggregate table.
DefaultDef.FactCountMatchRef
DefaultDef.ForeignKeyMatch	This is used to identify foreign key columns in a candidate aggregate table given the name of a foreign key column of the base fact table.
DefaultDef.ForeignKeyMatchRef
DefaultDef.IgnoreMap	This is the template used to specify columns to be ignored.
DefaultDef.IgnoreMapRef
DefaultDef.LevelMap	This is the template that maps from a combination of level usage_prefix hierarchy_name level_name level_column_name
DefaultDef.LevelMapRef
DefaultDef.Mapper	This allows one to create an element that matches against a single template, where the template is an attribute.
DefaultDef.MeasureMap	This is the template that maps from a combination of measure measure_name, measure_column_name, and aggregate_name ("count", "sum", "avg", "min", "max", "distinct-count").
DefaultDef.MeasureMapRef
DefaultDef.NameMatcher	A NameMatcher is a CaseMatcher that prepends and appends regular expressions to a given string as part of creating the matching regular expression.
DefaultDef.Ref
DefaultDef.Regex	This element is used in a vector of child elements when one wishes to have one or more regular expressions associated with matching a given string.
DefaultDef.RegexMapper
DefaultDef.TableMatch	This is used to identify which tables in the database might be aggregate table of a given fact table.
DefaultDef.TableMatchRef
DefaultRecognizer	This is the default Recognizer.
DefaultRules	Container for the default aggregate recognition rules.
DefaultRuleTest	Testing the default aggregate table recognizer.
ExplicitRecognizer	This is the Recognizer for the aggregate table descriptions that appear in the catalog schema files; the user explicitly defines the aggregate.
ExplicitRules	A class containing a RolapCube's Aggregate tables exclude/include criteria.
ExplicitRules.Group	This class forms a collection of aggregate table explicit rules for a given cube.
ExplicitRules.NameTableDef
ExplicitRules.PatternTableDef	This class matches candidate aggregate table name with a pattern.
ExplicitRules.TableDef	This is the base class for the exact name based and name pattern based aggregate table mapping definitions.
JdbcSchema	Metadata gleaned from JDBC about the tables and columns in the star schema.
JdbcSchema.StdFactory
MultipleColsInTupleAggTest	Testcase for levels that contain multiple columns and are collapsed in the agg table.
NonCollapsedAggTest	Testcase for non-collapsed levels in agg tables.
Recognizer	Abstract Recognizer class used to determine if a candidate aggregate table has the column categories: "fact_count" column, measure columns, foreign key and level columns.
SpeciesNonCollapsedAggTest	Test case for non-collapsed levels in agg tables, based on the "Species" schema.
UsagePrefixTest	Validates the dimension attribute usagePrefix is correctly applied when querying aggregate tables.

Enum Summary

Enum	Description
JdbcSchema.TableUsageType
JdbcSchema.UsageType	Enumeration of ways that an aggregate table can use a column.
