public abstract static class ExplicitRules.TableDef extends Object
This is the base class for the exact name based and name pattern based aggregate table mapping definitions. It contains the mappings for the fact count column, optional ignore columns, foreign key mappings, measure column mappings and level column mappings.

    • getApproxRowCount

      public int getApproxRowCount()
      Returns an approximate number of rows in this table. A negative value indicates that no estimate is available.
      Returns:
      An estimated row count, or a negative value if no row count approximation was available.

    • isIgnoreCase

      public boolean isIgnoreCase()
      Return true if this name/pattern matching ignores case.

    • getStar

      public RolapStar getStar()
      Get the RolapStar associated with this cube.

    • getAggGroup

      public ExplicitRules.Group getAggGroup()
      Get the Group with which is a part.

    • getFactCountName

      protected String getFactCountName()
      Get the name of the fact count column.

    • setFactCountName

      protected void setFactCountName(String factCountName)
      Set the name of the fact count column.

    • getMeasuresFactCount

      public Map<String,String> getMeasuresFactCount()

    • getIgnoreColumnNames

      protected Iterator<String> getIgnoreColumnNames()
      Get an Iterator over all ignore column name entries.

    • getLevels

      public List<mondrian.rolap.aggmatcher.ExplicitRules.TableDef.Level> getLevels()
      Gets all level mappings.

    • getMeasures

      public List<mondrian.rolap.aggmatcher.ExplicitRules.TableDef.Measure> getMeasures()
      Gets all level mappings.

    • getIgnoreMatcher

      protected mondrian.rolap.aggmatcher.Recognizer.Matcher getIgnoreMatcher()
      Get Matcher for ignore columns.

    • getFactCountMatcher

      Get Matcher for the fact count column.

    • getMeasureFactCountMatcher

      protected mondrian.rolap.aggmatcher.Recognizer.Matcher getMeasureFactCountMatcher()

      public boolean columnsOK(RolapStar star, JdbcSchema.Table dbFactTable, JdbcSchema.Table dbTable, MessageRecorder msgRecorder)
      Checks that ALL of the columns in the dbTable have a mapping in the tableDef.

      It is an error if there is a column that does not have a mapping.

    • addIgnoreColumnName

      Adds the name of an aggregate table column that is to be ignored.

    • addFK

      protected void addFK(MondrianDef.AggForeignKey fk)

    • getAggregateFK

      protected String getAggregateFK(String baseFK)
      Get the name of the aggregate table's foreign key column that matches the base fact table's foreign key column or return null.

      Adds a Level.

    • add

      protected void add(mondrian.rolap.aggmatcher.ExplicitRules.TableDef.Measure measure)
      Adds a Measure.

    • matches

      public abstract boolean matches(String tableName)
