Detailed Description

template<typename T>
class RTT::Property< T >

A property represents a named value of any type with a description.

A property is a tuple of a name, a description and a variable of any type. It's purpose is to provide a hierarchical parameter of a component. They are grouped in PropertyBag objects and a Property can contain a PropertyBag itself.

If you do not provide a name nor description when constructing the Property object, it will be uninitialised and ready() will return false. Such an object may not be used (set(), get(),...) until it has been initialised from another Property. Otherwise, an exception (or assert) will be thrown.

Parameters:
TThe type of the data contained within the Property.
