Class ImmutableWorkflowCaller

java.lang.Object
com.yworkflow.common.caller.ImmutableWorkflowCaller
All Implemented Interfaces:
WorkflowCaller, Comparable<WorkflowCaller>
public class ImmutableWorkflowCaller extends Object implements WorkflowCaller
Immutable implementation of WorkflowCaller that stores a caller identity string. This class provides a thread-safe, immutable representation of a workflow caller that can be used for access control and audit purposes.

ImmutableWorkflowCaller instances are created with a caller identity string, which can be null for anonymous callers. The class implements proper comparison semantics and provides access to the caller value through the WorkflowCaller interface.

This implementation is used internally by the WorkflowCaller factory methods and provides the default behavior for caller identity management.
