Constructor & Destructor Documentation

DcmQuantPixelBoxArray::DcmQuantPixelBoxArray (  unsigned long  entries  ) 
 

constructor.

Creates an array with the given number of pixel boxes.

Parameters:
entries number of entries in array, must be > 0.

Referenced by operator[]().

Member Function Documentation

DcmQuantPixelBox& DcmQuantPixelBoxArray::operator[] (  size_t  idx  )  [inline]
 

looks up an array element

Parameters:
idx index, must be smaller than the number of entries with which this object was initialized
Returns:
non-const reference to DcmQuantPixelBox struct

Definition at line 88 of file diqtpbox.h.
