Class Scenario2WrapperIRGenerator

java.lang.Object
org.ek9lang.compiler.phase7.Scenario2WrapperIRGenerator
public final class Scenario2WrapperIRGenerator extends Object
Generates IR for Scenario 2 delegation wrappers.

When an extern generic type (e.g., List) is parameterized with a user-defined type (e.g., UserRecord), there's no pre-built Java class for this exact parameterization. This generator creates a delegation wrapper class that:

  • Has a delegate field of the base generic type (e.g., List)
  • Provides type-safe methods that delegate to the base type
  • Uses virtual dispatch for delegate calls (enabling polymorphism)

The generated wrapper follows the pattern established by pre-built wrappers like _List_8F118296... for List of String.
