- Constructor Detail
  - PlacementConstraint
```
public PlacementConstraint()
```
- Method Detail
  - setExpression
```
public void setExpression(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.
    
    Parameters:
    
    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.
  - getExpression
```
public String getExpression()
```
    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.
  - withExpression
```
public PlacementConstraint withExpression(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.
    
    Parameters:
    
    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:
    
    Returns a reference to this object so that method calls can be chained together.
  - 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 the 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 the selection to a group of valid candidates.

    PlacementConstraintType
  - 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 the 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 the selection to a group of valid candidates.

    PlacementConstraintType
  - 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 the 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 the selection to a group of valid candidates.
    
    Returns:
    
    Returns a reference to this object so that method calls can be chained together.
    
    See Also:
    
    PlacementConstraintType
  - withType
```
public PlacementConstraint withType(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.
    
    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 the selection to a group of valid candidates.
    
    Returns:
    
    Returns a reference to this object so that method calls can be chained together.
