Method Detail

type

public TaskDefinitionPlacementConstraintType type()

The type of constraint. The DistinctInstance constraint ensures that each task in a particular group is running on a different container instance. The MemberOf constraint restricts selection to be from a group of valid candidates.

If the service returns an enum value that is not available in the current SDK version, type will return TaskDefinitionPlacementConstraintType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from typeAsString().

Returns:

The type of constraint. The DistinctInstance constraint ensures that each task in a particular group is running on a different container instance. The MemberOf constraint restricts selection to be from a group of valid candidates.
