Method Detail

getOrigin

public CatalogModel getOrigin()

Description copied from interface: ResolvedCatalogModel

Returns the original, unresolved metadata object from the Catalog.

This method might be useful if catalog-specific object instances should be directly forwarded from the catalog to a factory.

public ResolvedSchema getResolvedInputSchema()

Description copied from interface: ResolvedCatalogModel

Returns a fully resolved and validated ResolvedSchema inputSchema.

Specified by:

getResolvedInputSchema in interface ResolvedCatalogModel

getResolvedOutputSchema

public ResolvedSchema getResolvedOutputSchema()

Description copied from interface: ResolvedCatalogModel

Returns a fully resolved and validated ResolvedSchema outputSchema.

Specified by:

getResolvedOutputSchema in interface ResolvedCatalogModel

toProperties

public Map<String,String> toProperties(SqlFactory sqlFactory)

Description copied from interface: ResolvedCatalogModel
