| OFListIterator (DcmQuantHistogramItem *) first | |

| list of (pointers to) DcmQuantHistogramItem objects | |
this is a helper class used by class DcmQuantColorHashTable.
It maintains a list of DcmQuantHistogramItem objects.
| 
 | inline | 
adds the given pixel to the list.
If the pixel is already contained in the list, it's integer value (counter) is increased and 0 is returned. Otherwise, a new entry with a counter of 1 is created and 1 is returned.
| colorP | pixel to add to the list | 
References list_.
| 
 | inline | 
searches the list for an entry that equals the given pixel value.
If found, the integer value assigned to that pixel is returned, otherwise returns -1.
| colorP | pixel to lookup in list |

| void DcmQuantHistogramItemList::moveto | ( | DcmQuantHistogramItemPointer * | array, | 
| unsigned long & | counter, | ||
| unsigned long | numcolors ) | 
this method moves the contents of this list into the given array.
The list becomes empty if the array is large enough to contain all list members.
| array | array of pointers to DcmQuantHistogramItem | 
| counter | When called, contains the index of the array element into which the first member of the list will be moved. Must be < numcolors. Upon return, contains the array index of the last element moved + 1. | 
| numcolors | number of elements in array | 
| 
 | inline | 
inserts a new DcmQuantHistogramItem at the beginning of the list.
| colorP | pixel value assigned to the new object in the list | 
| value | integer value assigned to the new object in the list |
