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.
delimiter(@NonNull String delimiter)

endOffset(@NonNull String endOffset)
public static Storage.BlobListOption endOffset(@NonNull String endOffset)
Returns an option to set a endOffset to filter results to objects whose names are
