Detailed Description

iRegistry interface implementation.

This class implements the global registry for interfaces. Interfaces are stored in a QHash container and quarded with QWeakPointer.

Member Function Documentation

virtual QObject* eVaf::Common::Internal::Registry::queryInterface ( QString const &  name ) const

virtual

Returns the interface by its name.

Parameters

name	Name of the interface

Returns

Interface implementation or NULL if not found.

This function queries the global registry for the interface by its name. It returns a pointer to the implementation of the interface or NULL if no such interface is found.

Use the qobject_cast<>() function to type cast the returned pointer to the required interface class. Always check for NULL in case there is a mismatch in interface versions or no such interface is found.

Implements eVaf::Common::iRegistry.

virtual bool eVaf::Common::Internal::Registry::registerInterface ( QString const &  name, QObject *  obj  )

virtual

Registers an interface.

Parameters

name	Name of the interface
obj	Object implementing the interface

Returns

True if ok; false if registering failed

This function registers a new interface in the global registry of interfaces.

If an interface with this name already exists, then the new interface implementation overwrites the old implementation.

Implements eVaf::Common::iRegistry.
