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. UsememberOf
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. UsememberOf
to restrict the selection to a group of valid candidates. - See Also:

expression
A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is
distinctInstance
. For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide.- Returns:
- A cluster query language expression to apply to the constraint. The expression can have a maximum length
of 2000 characters. You can't specify an expression if the constraint type is

toBuilder
Description copied from interface:ToCopyableBuilder

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. -
