|
inline |
Generate an Epetra_MapColoring
object.
Provide access on the coloring thru the EpetraEXT color class Epetra_MapColoring
. This methods requires EpetraEXT support.
|
inlinevirtualinherited |
Method which returns the number (global) of colors used.
|
inlinevirtualinherited |
Return the number of local elements of a given color.
theColor | The wanted color. |
|
inlinevirtualinherited |
Fill user-allocated list (of length len) with the local element ids for LOCAL elements of the given color.
theColor | the wanted color |
elementList | an array to receive local elements of the given color |

|
inlinevirtualinherited |
Give access of the color assignments array that is owned by the current processor.
size | [out] Number of elements in the array. |
array | [out] Pointer to the color assignements array inside the object. |
