public final PlacementConstraintType type()
The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.
If the service returns an enum value that is not available in the current SDK version, type
will return
PlacementConstraintType.UNKNOWN_TO_SDK_VERSION
. The raw value returned by the service is available from
typeAsString()
.
