Class OperatorDeclarationMetaData

java.lang.Object

org.ek9lang.compiler.phase7.calls.OperatorDeclarationMetaData

All Implemented Interfaces:

Function<String, CallMetaDataDetails>

public final class OperatorDeclarationMetaData
extends Object
implements Function<String, CallMetaDataDetails>

THE OperatorMap-derived call metadata of a declared EK9 operator - the second honest source of SynthesisedCallMetaData, used when the target type carries no resolvable member for the callee. Hold an instance.

The live case is an operator on a function type: delegate? lowers to _isSet on a FunctionSymbol, which is not an aggregate and so has no members to resolve. Nothing is lost by reading the declaration instead of a symbol - a function's ? is fixed language surface, not something a user can override. This is the same derivation the parsed path uses for a path-B operator (CallDetailsBuilder), and both use this class so the two cannot drift.

OperatorDeclarationMetaDataIfAny is the same answer for a name that may not be an operator.

Throws:

CompilerException - when the name is not a declared operator either - then there is no honest source and the site is either a phase 3 gap or compiler plumbing
