Interface MetadataProvider

All Known Implementing Classes:

MdmPropertyProvider, MdmMetadataProvider, MdmMetadataProvider, FundamentalMetadataProvider

public abstract interface MetadataProvider

An interface for an object that provides access to the metadata describing a particular data store or the properties of the objects in that data store. The data must support a metadata model that is compatible with that of the MetadataProvider. For example, the MdmMetadataProvider class supports the MDM metadata model. In order to use an instance of MdmMetadataProvider for access to a given data store, that data store must support compatible metadata. An example is the metadata created by the OLAP metadata APIs.

The MetadataProvider interface supplies only the existence of a unique identifier. Additional features, such as the ability to find out if the connection to the underlying metadata is open and navigation from one MetadataObject to another, are provided by a class that implements this interface, because such features are specific to a particular metadata model (such as MDM).

In addition to classes that give access to metadata and properties, this interface is implemented by a class that gives access to objects representing fundamental operations such as addition and fundamental data types such as Integer. For the most part, these classes are used by internal OLAP API code, not by application developers.
