Combined or transformed datastores — Datastores created using thecombineandtransformfunctions.
Custom datastores — Datastores created using the custom datastore framework. SeeDevelop Custom Datastore.
Extended Capabilities
Thread-Based Environment Run code in the background using MATLAB®backgroundPoolor accelerate code with Parallel Computing Toolbox™ThreadPool.
Usage notes and limitations:
In a thread-based environment, you can usehasdataonly with the following datastores:
ImageDatastoreobjects
CombinedDatastoreorTransformedDatastoreobjects you create fromImageDatastoreobjects by usingcombineortransform
You can usehasdatawith other datastores if you have Parallel Computing Toolbox™. To do so, run the function using a process-backed parallel pool instead of usingbackgroundPoolorThreadPool(use eitherProcessPoolorClusterPool).
