Note that all Batch attributes are cached locally, and are only updated when you create a client-side batch object or when you explicitly update this cache (by calling the appropriate update function - GRBupdatebatch for C, update for Python, etc.).

For examples of how to query or modify attributes, refer to our Attribute Examples.
