gcs_dir: List bucket/folder/object

In Jiefei-Wang/GCSConnection: Creating R Connection with Google Cloud Storage

Description

list objects in a bucket/folder or get the description of a file. You can change the current direction via '[[' or '$' operator. '..' can be used to go to the parent folder. For reducing the number of request sent to the network, it is recommended to add a trailing slash if the path is a folder.

Usage

gcs_dir(path, delimiter = TRUE, billing_project = gcs_get_requester_pays())

Arguments

path	The character path to a bucket/folder/file or a FolderClass/FileClass object returned by 'gcs_dir'.
delimiter	Logical(1), whether to use '/' as a path delimiter. If not, the path will be treated as the path to a file even when it ends with '/'
billing_project	logical(1) or character(1). If logical, whether users should pay the cost for accessing the data. The billing project is the project ID in 'gcs_get_billing_project()'. If character, it represents the project ID that will be charged by Google.

Value

'FolderClass' object or a 'FileClass' object
