Interface PartMapper_v0_3

All Known Implementing Classes:
PartMapper_v0_3Impl
public interface PartMapper_v0_3
Bidirectional mapper for converting Part types between A2A Protocol v0.3 and v1.0.

Handles polymorphic Part conversion for:

Key differences:

  • v0.3: Part types are records with accessor methods (e.g., text(), metadata())
  • v1.0: Part types are records with accessor methods (e.g., text(), metadata())

Uses manual instanceof dispatch to handle polymorphic conversion.

      Parameters:
      v03 - the v0.3 part
      Returns:
      the equivalent v1.0 part
      Throws:
      InvalidRequestError - if the part type is unrecognized

      Parameters:
      v10 - the v1.0 part
      Returns:
      the equivalent v0.3 part
      Throws:
