HXLD🔗

Name🔗

HXLD — Represents an instance of an XLD object-(array).

Base class🔗

HObject — Represents an instance of an iconic object(-array). Base class for images, regions and XLDs

DestructorFinalizer🔗

This operator is not available as a class member but will be called automatically by the destructor. This occurs when a local variable goes out of scope or an instance on the heap is deleted.This operator is not available as a class member but will be called automatically when the resources of the object instances are to be released. This occurs in the finalization stage of garbage collection, or upon an explicit call of the Dispose() method.

 
ClearObj Delete an iconic object from the HALCON database.
