Method Detail

setType

public void setType(String 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 selection to a group of valid candidates.

Parameters:

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 selection to a group of valid candidates.

getType

public String getType()

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 selection to a group of valid candidates.

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 selection to a group of valid candidates.

withType

public PlacementConstraint withType(String 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 selection to a group of valid candidates.

Parameters:

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 selection to a group of valid candidates.

Returns:

Returns a reference to this object so that method calls can be chained together.

Parameters:

expression - A cluster query language expression to apply to the constraint. Note you cannot specify an expression if the constraint type is distinctInstance. For more information, see Cluster Query Language in the Amazon EC2 Container Service Developer Guide.

getExpression

public String getExpression()

A cluster query language expression to apply to the constraint. Note you cannot specify an expression if the constraint type is distinctInstance. For more information, see Cluster Query Language in the Amazon EC2 Container Service Developer Guide.

Returns:

A cluster query language expression to apply to the constraint. Note you cannot specify an expression if the constraint type is distinctInstance. For more information, see Cluster Query Language in the Amazon EC2 Container Service Developer Guide.

withExpression

public PlacementConstraint withExpression(String expression)

A cluster query language expression to apply to the constraint. Note you cannot specify an expression if the constraint type is distinctInstance. For more information, see Cluster Query Language in the Amazon EC2 Container Service Developer Guide.

Parameters:

expression - A cluster query language expression to apply to the constraint. Note you cannot specify an expression if the constraint type is distinctInstance. For more information, see Cluster Query Language in the Amazon EC2 Container Service Developer Guide.

Returns:

Returns a reference to this object so that method calls can be chained together.
