Technical - How can I remove a Target from a Dataset

The Vuforia SDK allows you to remove targets from a Dataset, only if the targets have not been loaded from a Device Database.

This practically means that you can only remove User Defined Targets (UDT). 

This can be achieved using the Dataset class methods.

JAVA (Android native):

myDataSet.destroy ( myUserDefinedTarget );

C++ (Android and iOS native):

myDataSet->destroy ( myUserDefinedTarget );

See also API reference:

C# (Unity):

myDataSet.Destroy( myUserDefinedTarget, true );

See also the API reference: https://developer.vuforia.com/resources/api/unity/class_data_set

Note that the Unity API - Destroy() method takes an additional boolean argument (true / false) to specify whether you want the gameObject associated to the target to be destroyed or not.
