As methods | |
As methods do "loose" conversion, they will convert the scalar value to the requested type if possible, else throw type_error. | |

A holder for an AMQP value.
A proton::value can hold any AMQP data value, simple or compound. It has assignment and conversion operators to convert its contents easily to and from native C++ types.
