Detailed Description

The MetaAnnotation class allows access to annotations.

Annotations can be used to store user-defined meta-data for classes, enums, methods and fields.

Usage

Annotations are basically a key-value pair. The key is always a QByteArray, while the value can be of arbitary type. This means you can also store complex types (Other than integers and strings) as long the type is registered in Qts meta system using Q_DECLARE_METATYPE.

The primary macro for this is NURIA_ANNOTATE. This macro takes two arguments, first being the key written as symbol and the second one being the value.

Annotations can be accessed using annotationCount() and annotation() in Nuria::Meta* classes.

Order of annotations

Annotations are always sorted by key in ascending order. There may be multiple annotations of the same key in any given element. If there are multiple annotations with the same key, the order they were written in is retained.
