enum class PathOperation
kotlin.Any  
↳  kotlin.Enum<androidx.ui.graphics.PathOperation>  
↳  androidx.ui.graphics.PathOperation 
Strategies for combining paths.
See also:
 Path.combine, which uses this enum to decide how to combine two paths.
Summary
Enum values  

Subtract the second path from the first path. 

Create a new path that is the intersection of the two paths, leaving the overlapping pieces of the path. 

Subtract the first path from the second path. 

Create a new path that is the union (inclusiveor) of the two paths. 

Create a new path that is the exclusiveor of the two paths, leaving everything but the overlapping pieces of the path. 
Enum values
difference
enum val difference : PathOperation
Subtract the second path from the first path.
For example, if the two paths are overlapping circles of equal diameter but differing centers, the result would be a crescent portion of the first circle that was not overlapped by the second circle.
See also:
 reverseDifference, which is the same but subtracting the first path from the second.
intersect
enum val intersect : PathOperation
Create a new path that is the intersection of the two paths, leaving the overlapping pieces of the path.
For example, if the two paths are overlapping circles of equal diameter but differing centers, the result would be only the overlapping portion of the two circles.
See also:
 xor, which is the inverse of this operation
reverseDifference
enum val reverseDifference : PathOperation
Subtract the first path from the second path.
For example, if the two paths are overlapping circles of equal diameter but differing centers, the result would be a crescent portion of the second circle that was not overlapped by the first circle.
See also:
 difference, which is the same but subtracting the second path from the first.
union
enum val union : PathOperation
Create a new path that is the union (inclusiveor) of the two paths.
For example, if the two paths are overlapping circles of equal diameter but differing centers, the result would be a figureeight like shape matching the outer boundaries of both circles.
xor
enum val xor : PathOperation
Create a new path that is the exclusiveor of the two paths, leaving everything but the overlapping pieces of the path.
For example, if the two paths are overlapping circles of equal diameter but differing centers, the figureeight like shape less the overlapping parts
