Method Details
-
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 returnPlacementConstraintType.UNKNOWN_TO_SDK_VERSION
. The raw value returned by the service is available fromtypeAsString()
.- 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.
- See Also:
-
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 returnPlacementConstraintType.UNKNOWN_TO_SDK_VERSION
. The raw value returned by the service is available fromtypeAsString()
.- 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.
- See Also:
-
expression
A cluster query language expression to apply to the constraint. You cannot specify an expression if the constraint type is
distinctInstance
. To learn more, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide.- Returns:
- A cluster query language expression to apply to the constraint. You cannot specify an expression if the
constraint type is
distinctInstance
. To learn more, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide.

toBuilder
Description copied from interface:ToCopyableBuilder
Take this object and create a builder that contains all of the current property values of this object.- Specified by:

equalsBySdkFields
Description copied from interface:SdkPojo
Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in anSdkPojo
class, and is generated based on a service model.If an
SdkPojo
class does not have any inherited fields,equalsBySdkFields
andequals
are essentially the same.- Specified by:
equalsBySdkFields
in interfaceSdkPojo
- Parameters:
obj
- the object to be compared with- Returns:
- true if the other object equals to this object by sdk fields, false otherwise.
-
toString
Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value. -
