function_property_map<UnaryFunction, Key, Ref>

This property map is an adaptor that converts a function object into either a Readable Property Map or a Lvalue Property Map. The category of the property map is based on whether the function's return type (as given by Ref) is a non-const reference type.

Template Parameters

Parameter	Description	Default
UnaryFunction	Must be a model of Unary Function that accepts an object of type Key as an argument and returns a result of type Ref.
Key	The key type of the property map.
Ref	The result type of the function.	boost::result_of<const UnaryFunction(const Key&)>::type
