Detailed Description

A holder for any AMQP value, simple or complex.

Friends And Related Function Documentation

T coerce ( const value & v )

For example:

uint64_t i = get<uint64_t>(x)

This will succeed if x contains any numeric value, but may lose precision if it contains a float or double value.

Exceptions

conversion_error if the value cannot be converted to T according to std::is_convertible

May be more efficient for complex values (arrays, maps, etc.)

T get ( const value & v )

For example:

uint64_t i = get<uint64_t>(x)

This will succeed if and only if x contains a uint64_t value.

Exceptions

conversion_error if contained value is not of type T.

May be more efficient for complex values (arrays, maps, etc.)
