HXLD (Class)

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

Finalizer

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 database.
