The value which comes last in collection and os will be the value included in the return. All options from os will override their counterparts in collection.

Parameters
Name Description
collection Collection<BlobWriteOption>
os BlobWriteOption[]
Returns

detectContentType()

public static Storage.BlobWriteOption detectContentType()

Returns an option for detecting content type. If this option is used, the content type is detected from the blob name if not explicitly set. This option is on the client side only, it does not appear in a RPC call.

Content type detection is based on the database presented by URLConnection#getFileNameMap()
