Currently one of the most common coding pattern, when working with
QMetaType types, is to switch over all types ids to convert a given
type id to a real c++ type. The pattern is not perfect, because of:
- code duplication - to convert type id to a real type a user has to
write own switch case
- maintenance - adding new type to QMetaType::Types doesn't propagate
to other parts of code.
Proposed type switcher can solve the issue by switching type id and
delegating found c++ type.
The class is created for internal use only and was created to simplify
common problems in QtDeclarative, QtScript and QVariant.
