Class TempMetadataAdapter

java.lang.Object

org.teiid.query.metadata.BasicQueryMetadataWrapper

org.teiid.query.metadata.TempMetadataAdapter

All Implemented Interfaces:

QueryMetadataInterface

public class TempMetadataAdapter
extends BasicQueryMetadataWrapper

This is an adapter class, it contains another instance of QueryMetadataInterface as well as a TempMetadataStore. It defers to either one of these when appropriate.

When a metadataID Object is requested for a group or element name, this will first check the QueryMetadataInterface. If an ID wasn't found there, it will then check the TempMetadataStore.

For methods that take a metadataID arg, this class may check whether it is a TempMetadataID or not and react accordingly.
