Package org.apache.flink.table.catalog

Class ContextResolvedModel

java.lang.Object

org.apache.flink.table.catalog.ContextResolvedModel

@Internal
public final class ContextResolvedModel
extends Object

This class contains information about a model and its relationship with a Catalog, if any.

There can be 2 kinds of ContextResolvedModel:

• A permanent model: a model which is stored in a Catalog and has an associated unique ObjectIdentifier.
• A temporary model: a model which is stored in the CatalogManager, has an associated unique ObjectIdentifier and is flagged as temporary.

The different handling of temporary and permanent model is Catalog and CatalogManager instance specific, hence for these two kind of models, an instance of this object represents the relationship between the specific ResolvedCatalogModel instance and the specific Catalog/CatalogManager instances. For example, the same ResolvedCatalogModel can be temporary for one catalog, but permanent for another one.
