LocationPreferenceConstraint (Flink : 2.0-SNAPSHOT API)

java.lang.Object
- java.lang.Enum<LocationPreferenceConstraint>
- - org.apache.flink.runtime.jobmanager.scheduler.LocationPreferenceConstraint

All Implemented Interfaces:

Serializable, Comparable<LocationPreferenceConstraint>
```
public enum LocationPreferenceConstraint
extends Enum<LocationPreferenceConstraint>
```
Defines the location preference constraint.
Currently, we support that all input locations have to be taken into consideration and only those which are known at scheduling time. Note that if all input locations are considered, then the scheduling operation can potentially take a while until all inputs have locations assigned.

    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (LocationPreferenceConstraint c : LocationPreferenceConstraint.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared

```
public static LocationPreferenceConstraint valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
