$CloudObjectNameFormat

$CloudObjectNameFormat

is the default setting used for the CloudObjectNameFormat option when constructing a CloudObject.

Details

  • The original default setting for $CloudObjectNameFormat is usually Automatic.
  • Possible settings include:
  • AutomaticUUID for anonymous objects; $UserURLBase for named objects
    "UserURLBase"$UserURLBase and the object path
    "CloudUserID"$CloudUserID and the object path
    "CloudUserUUID"$CloudUserUUID and the object path
    "UUID"object UUID

Examples

Basic Examples  (1)

By default, newly created named cloud objects use $UserURLBase to format the username in their URLs:

Its actual value can be obtained with $UserURLBase:

Change the name format to the user UUID:

A named object uses the user UUID in the URL:

Possible Issues  (1)

$CloudObjectNameFormat with a value of "UUID" cannot be applied if the destination is a named CloudObject that does not exist.

First, create a cloud object:

Check that the cloud object exists in the cloud:

Because it exists in the cloud, it has a known "UUID" associated with it:

Here, the content of the cloud object is replaced with 456 and the URL of the cloud object is given in "UUID" form:

Delete the object:

The named cloud object no longer exists, so the newly created cloud object is not returned in UUID format because the cloud object was created in "UserURLBase" format:

Delete the object:

Here, the destination is not using the CloudObject constructor, so the cloud object is constructed with a UUID:
