ObjectPath Class Reference

The ObjectPath class. More...

Detailed Description

The ObjectPath class.

A path in the QObject hierarchy, using names and identifiers. See {IdentifiedObject}.

If the object id is not known at compile time a path may be created using ObjectPath::pathFromObject.

Example:

ObjectPath p{ {"MyObject", 0}, {"SomeSubObjectInACollection", 27} };
ObjectPath
The ObjectPath class.
Definition ObjectPath.hpp:37

Note : this class is mostly superseded by Path<T> which adds type-safety.

Member Function Documentation

◆ find()

template<class T >
T & ObjectPath::find ( const score::DocumentContext &  ctx) const
inline

find the object described by the ObjectPath

Returns
A pointer to the object, or nullptr if it is not found

This search starts from qApp.

Todo:

(maybe) a way to specify custom ways of finding an object (for instance if obj->blurb() == Ding::someDing)

search starting from another object, for more performance.

◆ try_find()

template<class T >
T * ObjectPath::try_find ( const score::DocumentContext &  ctx) const
inlinenoexcept

Tries to find an object.

Returns
null if the object does not exist.
