mondrian.rolap.aggmatcher.ExplicitRules.TableDef

Direct Known Subclasses:

ExplicitRules.PatternTableDef

Enclosing class:

ExplicitRules

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.

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.
