datasrc: A 'datasrc'

In shunsambongi/dsi: Interfaces for data sources and datasets

Description

At a hight level, a datasrc represents a group of data sets. So you can query what datasets it has using list_datasets() and read and write datasets using read_dataset() and write_dataset(). At a lower level, a datasrc is more like a dynamic connection to such data source. This allows it to query the data source for the requested data. At the lowest level, a datasrc is a list of arguments (driver and named parameters) required to connect to a data source. This allows it to automatically create a temporary connection when needed to query the database.

Usage

datasrc(.name, .drv, ..., .subclass = NULL)

Arguments

.name	datasrc name
.drv	datasrc driver
...	named arguments for connecting to datasrc
.subclass	character vector of subclasses
