Member Function Documentation

CreateDefaultEntry() [1/2]

unique_ptr< CatalogEntry > duckdb::DefaultGenerator::CreateDefaultEntry ( ClientContext &  context, const string &  entry_name  )

virtual

Creates a default entry with the specified name, or returns nullptr if no such entry can be generated.

Reimplemented in duckdb::DefaultTypeGenerator, duckdb::DefaultTableFunctionGenerator, duckdb::DefaultCoordinateSystemGenerator, duckdb::DefaultFunctionGenerator, and duckdb::DefaultViewGenerator.

                                                                                                              {
    throw InternalException("CreateDefaultEntry with ClientContext called but not supported in this generator");
}

CreateDefaultEntry() [2/2]

unique_ptr< CatalogEntry > duckdb::DefaultGenerator::CreateDefaultEntry ( CatalogTransaction  transaction, const string &  entry_name  )

virtual

                                                                                        {
    if (!transaction.context) {
        // no context - cannot create default entry
        return nullptr;
    }
    return CreateDefaultEntry(*transaction.context, entry_name);
}

GetDefaultEntries()

virtual vector< string > duckdb::DefaultGenerator::GetDefaultEntries ( )

pure virtual

Get a list of all default entries in the generator.

Implemented in duckdb::DefaultSchemaGenerator, duckdb::DefaultTypeGenerator, duckdb::DefaultTableFunctionGenerator, duckdb::DefaultCoordinateSystemGenerator, duckdb::DefaultFunctionGenerator, and duckdb::DefaultViewGenerator.

LockDuringCreate()

virtual bool duckdb::DefaultGenerator::LockDuringCreate ( ) const

inlinevirtual

Whether or not we should keep the lock while calling CreateDefaultEntry If this is set to false, CreateDefaultEntry might be called multiple times in parallel also for the same entry Otherwise it will be called exactly once per entry

                                          {
        return false;
    }
