public abstract class MdmAttribute

extends MdmDimensionedObject

implements MdmQueryColumn

The abstract base class for an MdmDimensionedObject that represents one or more characteristic of the members of an MdmDimension. An MdmAttribute relates one member of the MdmDimension to one or more values. For example, the end date MdmAttribute of an MdmTimeDimension relates an end date to each member of an MdmTimeDimension. The data type of an MdmAttribute can be any of the OLAP Java API data types. A value of MdmAttribute can be a boolean, a Date, a number, a String, an MdmSource, or other kinds of objects.

An MdmAttribute is an MdmDimensionedObject because it has elements that are organized by an MdmDimension. For example, the end date MdmAttribute has one element (with a value that specifies a date) for each member of the MdmTimeDimension associated with it.

An application finds an existing attribute or creates a new one by using the appropriate method of the MdmPrimaryDimension that dimensions it. For example, the findOrCreateBaseAttribute method of an MdmPrimaryDimension gets an existing MdmBaseAttribute or creates a new one. An application can also get attributes of a dimension or level by using methods such as getShortValueDescriptionAttribute of an MdmPrimaryDimension and getLevelAttribute of an MdmLevelHierarchy.

Sometimes, not all of the members of an MdmDimension relate to the values of an MdmAttribute. For example, an MdmLevelHierarchy that represents a dimension of product items might have an attribute at the lowest level that relates a color to the items. The color attribute does not apply to members at higher levels of the hierarchy. If an MdmAttribute does not apply to a member of an MdmDimension, then the attribute value for that member is null.

Some MdmAttribute objects provide a relation that is one-to-many, rather than one-to-one. Therefore, a member in an MdmDimension might map to a whole set of MdmAttribute elements. For example, the MdmAttribute that is the ancestors attribute of an MdmHierarchy relates each member of the MdmHierarchy to the set of the MdmHierarchy members that are the ancestors of it.
