Create fs connector — connector

Initializes the connector for file system type of storage. See ConnectorFS for details.

Usage

connector_fs(path, extra_class = NULL)

Arguments

path: character Path to the file storage.
extra_class: character Extra class to assign to the new connector.

Value

A new ConnectorFS object

Details

The extra_class parameter allows you to create a subclass of the ConnectorFS object. This can be useful if you want to create a custom connection object for easier dispatch of new s3 methods, while still inheriting the methods from the ConnectorFS object.
