Detailed Description

A buffer to store and retrieve objects.

Sort of a variant, but does not keep track of the nature of the stored data, since that knowledge is available via the current parser state.

emplace() [2/2]

template<typename T >

inline

Instantiate a T in here from t.

Definition at line 288 of file parser.h.

move()

template<typename T >

void isc::eval::EvalParser::value_type::move ( self_type & that )

inline

Move the content of that to this.

Destroys that.

Definition at line 359 of file parser.h.

References as(), destroy(), emplace(), and swap().

Here is the call graph for this function:

swap()

template<typename T >

void isc::eval::EvalParser::value_type::swap ( self_type & that )

inline

Swap the content with that, of same type.

Both variants must be built beforehand, because swapping the actual data requires reading it (with as()), and this is not possible on unconstructed variants: it would require some dynamic testing, which should not be the variant's responsibility. Swapping between built and (possibly) non-built is done with self_type::move ().
