Method SignatureEquals

common/decls/decls.go:718–732

SignatureEquals determines whether the incoming overload declaration signature is equal to the current signature. Result type, operand trait, and strict-ness are not considered as part of signature equality.

(other *OverloadDecl)

//
// Result type, operand trait, and strict-ness are not considered as part of signature equality.
func (o *OverloadDecl) SignatureEquals(other *OverloadDecl) bool {
	if o == other {
		return true
	}
	if o.ID() != other.ID() || o.IsMemberFunction() != other.IsMemberFunction() || len(o.ArgTypes()) != len(other.ArgTypes()) {
		return false
	}
	for i, at := range o.ArgTypes() {
		oat := other.ArgTypes()[i]
		if !at.IsEquivalentType(oat) {
			return false
		}
	}
	return o.ResultType().IsEquivalentType(other.ResultType())
}

// SignatureOverlaps indicates whether two functions have non-equal, but overloapping function signatures.
