| DcmQuantHistogramItemList () | |
| constructor | |
| ~DcmQuantHistogramItemList () | |
| destructor. Destroys all objects pointed to by list. | |
| void | moveto (DcmQuantHistogramItemPointer *array, unsigned long &counter, unsigned long numcolors) |
| this method moves the contents of this list into the given array. | |
| int | lookup (const DcmQuantPixel &colorP) |
| searches the list for an entry that equals the given pixel value. | |
| unsigned long | add (const DcmQuantPixel &colorP) |
| adds the given pixel to the list. | |
| void | push_front (const DcmQuantPixel &colorP, int value) |
| inserts a new DcmQuantHistogramItem at the beginning of the list. | |

Private Member Functions | |
| OFListIterator (DcmQuantHistogramItem *) first | |
| temporary iterator used in various methods; declared here for efficiency reasons only. | |
| OFListIterator (DcmQuantHistogramItem *) last | |

Private Attributes | |
| OFList< DcmQuantHistogramItem * > | list_ |
| 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 |
