Detailed Description

Common base class to all tuple types. The base class provides a public function to check if a particular element is set, meaning that one can test this generically without knowing the actual tuple element types.

Internally, the base class performs the state management tracking which elements are set through a bitmask.

For efficiency, we currently limit the maximum number of tuple elements to

1. This could be changed if deemed necessary.

Constructor & Destructor Documentation

TupleBase() [1/2]

hilti::rt::TupleBase::TupleBase ( )

protecteddefaultnoexcept

Constructor marking all elements as initially unset.

TupleBase() [2/2]

hilti::rt::TupleBase::TupleBase ( tuple::detail::AllSetTag  , uint64_t  num_elements  )

inlineprotected

Constructor marking all elements as initially set.

Parameters

tag	tag to select this constructor
num_elements	number of elements in the tuple

Member Function Documentation

hasValue()

constexpr bool hilti::rt::TupleBase::hasValue ( size_t  idx ) const

inlineconstexprnoexcept

Returns true if the element at index idx is set. If idx is beyond the number of valid tuple elements the result is undefined.

set()

void hilti::rt::TupleBase::set ( size_t  idx )

inlineprotected

Mark a specific element as set.

Parameters

idx	index of the element to mark as set

Member Data Documentation

MaxElements

constexpr size_t hilti::rt::TupleBase::MaxElements = 64

staticconstexprprotected

Maximum number of tuple elements supported.
