Interface FileContentMapper_v0_3

All Known Implementing Classes:

FileContentMapper_v0_3Impl

public interface FileContentMapper_v0_3

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

Handles polymorphic FileContent conversion for:

• FileWithBytes_v0_3 ↔ FileWithBytes
• FileWithUri_v0_3 ↔ FileWithUri

Key differences:

• v0.3: FileWithBytes and FileWithUri are simple records
• v1.0: FileWithBytes is a complex class with lazy loading; FileWithUri is a simple record

The conversion preserves the mimeType, name, and content (bytes or uri) fields across both versions.
