Detailed Description

A WEM comprises a number of WEMPatches.

The WEM is derived from Base and can be used as a data structure in a MeVisLab network. The WEM ownership is managed via smart pointers, make sure to use a WEMPtr to manage newly created WEM objects.

Definition at line 88 of file WEM.h.

Constructor & Destructor Documentation

◆ WEM() [1/2]

ml::WEM::WEM ( )

Standard constructor.

◆ WEM() [2/2]

ml::WEM::WEM ( const WEM & wem )

Copy constructor.

◆ ~WEM()

ml::WEM::~WEM ( )

overrideprotected

The WEM destructor is protected since the WEM ownership is managed by the WEMPtr intrusive smart pointer.

If you encounter code that tries to delete a WEM object, you will very likely need to change the usage of a WEM* to a WEMPtr and replace the delete call with a NULL assignment.
