This class derives from the vnl_vector<> class. Its size is assigned at construction time (run time) and can not be changed afterwards except by using assignment to another <a class="el" href="classitk_1_1Array.html" title="Array class with size defined at construction time.">Array</a>.<p>

Similar to the previous method. In the above method, the size must be seperately set prior to using user-supplied data. This introduces an unnecessary allocation step to be performed. This method avoids it and should be used to import data whereever possible to avoid this. Set the pointer from which the data is imported. If "LetArrayManageMemory" is false, then the application retains the responsibility of freeing the memory for this data. If "LetArrayManageMemory" is true, then this class will free the memory when this object is destroyed.
