Class CalleeOfCall

java.lang.Object

org.ek9lang.compiler.phase9.CalleeOfCall

All Implemented Interfaces:

Function<CallInstr, Optional<ScopedSymbol>>

final class CalleeOfCall
extends Object
implements Function<CallInstr, Optional<ScopedSymbol>>

THE symbol an IR call runs, read back from what the call names: its target type (a user construct of the program's IR first, else a type or function the program resolves by fully qualified name - a core type, a parameterisation), the method by its IR name (OperatorMap.resolvedMethodName(MethodSymbol), so _addAss finds +=) and the fully qualified types of its parameters; a function's _call is the function itself. Empty when the names do not lead to exactly one symbol. Phase 9 needs it where a fact of the callee - what it may keep, RETAINS - decides an IR statement (the store barrier, S2b); the call itself carries only names.
