Interface WorkflowAttributeRegister<T>

Type Parameters:
T - the type of data returned by the register
public interface WorkflowAttributeRegister<T>
Interface for implementing custom workflow attribute registers. WorkflowAttributeRegister provides the mechanism for loading and registering transient attributes from external sources during workflow execution.

Attribute registers are used to load data that should be available as transient attributes for a single workflow invocation. They can retrieve data from databases, external services, configuration systems, or any other data source required by the workflow.

Custom attribute registers are registered with the workflow engine through the ExtensionProvider and can be referenced in workflow definitions by type and value.
