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.

References AGENT__ASSERT.

template<typename T >
void isc::agent::AgentParser::semantic_type::move ( self_type that)
inline

Move the content of that to this.

Destroys that.

Definition at line 348 of file agent_parser.h.

References as(), and destroy().

+ Here is the call graph for this function:

template<typename T >
void isc::agent::AgentParser::semantic_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 ().
