KaCallCandidateInfo

KaCallCandidateInfo represents one of the candidates considered during overload resolution of a call. Unlike KaErrorCallInfo.candidateCalls, retrieving a candidate via KaCallCandidateInfo does not imply that the call is erroneous — you can list candidates on successful code too.

Hierarchy

Members

val candidate: KaCall: The candidate represented as a KaCall (the legacy base type).
val isInBestCandidates: Boolean: Whether the candidate is in the final set the compiler considered. Multiple best candidates indicate ambiguity.

`KaApplicableCallCandidateInfo`

A candidate that could be called at the site — its arguments are complete and assignable, and its type arguments fit all the constraints.

`KaInapplicableCallCandidateInfo`

A candidate that could not be called at the site.

val diagnostic: KaDiagnostic: The reason for the candidate's missing applicability (e.g. argument type mismatch, missing value for a parameter, type-argument constraint violation).
