public class MdmDerivedMeasure
An MdmMeasure
that has values that Oracle OLAP derives from an Expression
. The values of an MdmDerivedMeasure
are calculated on the fly by Oracle OLAP and are not stored in the database. An MdmDerivedMeasure
does not have an associated ConsistentSolveSpecification
.
With the
method of an findOrCreateDerivedMeasure
MdmCube
, you can get an existing MdmDerivedMeasure
or create a new one. Committing the Transaction
in which you create a derived measure makes the MdmDerivedMeasure
a persistent object. It adds the MdmDerivedMeasure
to the data dictionary, which makes it available to other applications.
Method Summary | |

getLoopDenseOverride() Gets the value of the OLAP DML $LOOP_DENSE system property of the measure in the analytic workspace. |
java.lang.String |
getLoopVarOverride() Gets the value of the OLAP DML $LOOP_VAR system property for the measure in the analytic workspace. |
Expression |
getMeasureExpression() Gets the Expression that determines the values of this MdmDerivedMeasure . |
SQLDataType |
getSQLDataType() Gets the SQL data type for this MdmDerivedMeasure . |
void |
setLoopDenseOverride(java.lang.String value) Specifies the OLAP DML dimensions for the OLAP DML $LOOP_DENSE system property of the measure in the analytic workspace. |
void |
setLoopVarOverride(java.lang.String value) Specifies the OLAP DML variables for the OLAP DML $LOOP_VAR system property for the measure in the analytic workspace. |
void |
setMeasureExpression(Expression input) Specifies an Expression that determines the values of this MdmDerivedMeasure . |

$LOOP_VAR
system property for the measure in the analytic workspace.String
that contains the names of the OLAP DML variables that are specified by the $LOOP_VAR
property.public final void setLoopVarOverride(java.lang.String value)
$LOOP_VAR
system property for the measure in the analytic workspace. The $LOOP_VAR
property applies to the underlying formula for the derived measure. For information on the $LOOP_VAR
property, see Oracle OLAP DML Reference.
The value specified by this method overrides the default value used by Oracle OLAP. You might want to use this method if the Expression
of the MdmDerivedMeasure
includes an OLAPDMLExpression
.
value
- A String
that contains the names of one or more variables on separate lines, as in "var1\nvar2"

$LOOP_DENSE
system property of the measure in the analytic workspace.String
that contains the names of the OLAP DML dimensions that are specified by the $LOOP_DENSE
property.public final void setLoopDenseOverride(java.lang.String value)
$LOOP_DENSE
system property of the measure in the analytic workspace. The $LOOP_DENSE
property applies to the underlying formula for the derived measure. For information on the $LOOP_DENSE
property, see Oracle OLAP DML Reference.
The value specified by this method overrides the default value used by Oracle OLAP. You might want to use this method if the Expression
of the MdmDerivedMeasure
includes an OLAPDMLExpression
.
value
- A String
that contains the names of one or more dimensions on separate lines, as in "dim1\ndim2"
