Interface TaskMapper_v0_3

All Known Implementing Classes:

TaskMapper_v0_3Impl

public interface TaskMapper_v0_3

Bidirectional mapper for converting Task between A2A Protocol v0.3 and v1.0.

Key differences:

• v0.3: Task is a record with accessor methods (e.g., id(), status())
• v1.0: Task is a record with accessor methods (e.g., id(), status())
• v0.3 has a kind field with kind() method
• v1.0 has a kind() method from the StreamingEventKind interface

The conversion involves mapping nested types:

• TaskStatus via TaskStatusMapper_v0_3
• Artifact list via ArtifactMapper_v0_3
• Message history list via MessageMapper_v0_3
