Detailed Description

template<class K, class T>
class proton::map< K, T >

A collection of key-value pairs.

Used to access standard AMQP property, annotation, and filter maps attached to proton::message and proton::source.

This class provides only basic get() and put() operations for convenience. For more complicated uses (iteration, preserving order, and so on), convert the value to a standard C++ map type such as std::map. See message_properties.cpp and AMQP and C++ types.
