Class DelegateLoad

java.lang.Object

org.ek9lang.compiler.phase7.support.DelegateLoad

public final class DelegateLoad
extends Object

THE load of a wrapper's delegate field, borrowed for the scope - shared by the constrained types (ConstrainedTypeInstrs) and the Scenario-2 wrappers (Scenario2WrapperHelper), which each had a byte-identical private copy (DFN-3, MONO-8). Hold one and use it; never hand-write the LOAD_FIELD and its borrow.

  delegateVar = LOAD_FIELD objectVar.delegate (ownerType -> delegateType)
  borrowed in scopeId (OwnershipStatements.borrowInScope(String, String, DebugInfo))
