deferred class ColorMap from Aspect inherits TShared from MMgt
---Version: 0.0
---Purpose: This class defines a ColorMap object.
---Keywords:

---References:
uses
Color from Quantity,

SequenceOfColorMapEntry from Aspect
raises

is
Initialize( type : TypeOfColorMap from Aspect );
Type( me )
returns TypeOfColorMap from Aspect is static;
---Level: Public
Size( me ) returns Integer from Standard is static;
---Level: Public
---Purpose: Returns the Allocated colormap Size
Index( me ; aColormapIndex : Integer ) returns Integer from Standard
---Level: Public
---Purpose: Returns the ColorMapEntry.Index of the ColorMap
-- at rank <aColormapIndex> .
raises BadAccess from Aspect is static;
---Trigger: Raises BadAccess if the index less than 1 or
-- greater than Size.

---Level: Public
---Purpose: Return the value of the <Index>th element of
-- the ColorMap
raises BadAccess from Aspect is static;
---Trigger: Raises BadAccess if the index less than 1 or
-- greater than Size.
---C++: return const &
FindColorMapIndex ( me ;
AColorMapEntryIndex : Integer from Standard )
returns Integer from Standard
---Level: Public
---Purpose: Returns the index in the ColorMap of the
-- ColorMapEntry.Index() equal to <AnEntryIndex>.
raises BadAccess from Aspect is deferred ;
---Trigger: Raises BadAccess if the index is not defined in the
-- ColorMap.
FindEntry ( me ; AColorMapEntryIndex : Integer from Standard )
returns ColorMapEntry from Aspect
---Level: Public
---Purpose: Returns the ColorMapEntry with ColorMapEntry.Index()
-- equal to <AnEntryIndex>.

returns Integer from Standard is deferred ;
---Level: Public
---Purpose: Returns the index in the ColorMap of the
-- nearest matching ColorMapEntry
NearestEntry( me ; aColor : Color from Quantity )
returns ColorMapEntry from Aspect is deferred ;
---Level: Public
---Purpose: Returns the nearest ColorMapEntry that match aColor .
---C++: return const &
AddEntry (me : mutable; aColor : Color from Quantity)
returns Integer from Standard is deferred;
---Level: Public
---Purpose: Search an identical color entry in the color map <me>
-- and returns the ColorMapEntry Index if exist.
-- Or add a new entry and returns the computed ColorMapEntry index used.
