Method Detail

expression

public final String expression()

A cluster query language expression to apply to the constraint. You cannot specify an expression if the constraint type is distinctInstance. For more information, see Cluster query language in the Amazon ECS Developer Guide.

Returns:

A cluster query language expression to apply to the constraint. You cannot specify an expression if the constraint type is distinctInstance. For more information, see Cluster query language in the Amazon ECS Developer Guide.

type

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().

Returns:

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.

typeAsString

public final String typeAsString()

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().

Returns:

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.
