An MdmObject
that represents a measure, dimension, or other set of data (such as an attribute). Thus, this abstract class is the basis for some important MDM metadata classes, such as the following concrete subclasses of MdmSource
:
MdmAttribute
MdmLevelHierarchy
MdmLevel
MdmMeasure
MdmStandardDimension
To retrieve the data values that an MdmSource
represents, an application calls the getSource
method of the MdmSource
. The method returns a Source
that an application can use to create queries on the data that this MdmSource
represents.
A Source
returned by the getSource
method of an MdmSource
is called a primary Source
. An application creates a query by using a method of the primary Source
to specify a selection of its elements, or a calculation or some other manipulation of the data.

Method Detail |
public FundamentalMetadataObject getDataType()
MdmSource
. The data type is a FundamentalMetadataObject
that represents one of the following OLAP API data types:
FundamentalMetadataObject
that represents the OLAP API data type of this MdmSource
.public final MtmSourceMap getSourceMap() throws MetadataNotFoundException
MtmSourceMap
for this MdmSource
. The MtmSourceMap
maps the elements of this MdmSource
to data in the relational database.MtmSourceMap
for this MdmSource
.public final Source getSource()
Source
through which an application can create queries on the data represented by this MdmSource
.
The returned Source
has no outputs. If this MdmSource
is an MdmDimension
, then the returned Source
has no inputs. If the MdmSource
is an MdmDimensionedObject
(an MdmMeasure
or an MdmAttribute
), then the returned Source
has inputs that correspond to the dimensions of the MdmDimensionedObject
.
Source
through which an application can create queries on the data represented by this MdmSource
.public MetadataObject getType()
MdmSource
. The type is the MetadataObject
whose elements provide the pool from which the MdmSource
draws its elements. Typically, the type is either an MdmSource
or a FundamentalMetadataObject
that represents an OLAP API data type such as String, Integer, or Boolean.MetadataObject
that is the type of this MdmSource
.
