Static Methods

currentDirectory()

public static Storage.BlobListOption currentDirectory()

If specified, results are returned in a directory-like mode. Blobs whose names, after a possible #prefix(String), do not contain the '/' delimiter are returned as is. Blobs whose names, after a possible #prefix(String), contain the '/' delimiter, will have their name truncated after the delimiter and will be returned as Blob objects where only Blob#getBlobId(), Blob#getSize() and Blob#isDirectory() are set. For such directory blobs, (BlobId#getGeneration() returns null), Blob#getSize() returns 0 while Blob#isDirectory() returns true. Duplicate directory blobs are omitted.
