Enumeration Type Documentation

◆ dwBindSlot

enum dwBindSlot

The slot enum used when an application wants a dw module to bind some particular input data to an internal slot for future processing and unbinding.

Particularly the module expects an array of instances of such data structure hence maintaining an internal container for them. For example, dwObjectArray instances inputting to dwObjectInPathAnalyzer module
