Phan\Language\Element\PassByReferenceVariable::getVariadicElementUnionType PHP Method

getVariadicElementUnionType() public method

Variables can't be variadic. This is the same as getUnionType for variables, but not necessarily for subclasses. Method will return the element type (such as DateTime) for variadic parameters.
public getVariadicElementUnionType ( ) : UnionType
return Phan\Language\UnionType
    public function getVariadicElementUnionType() : UnionType
    {
        return $this->element->getVariadicElementUnionType();
    }
