@InterfaceAudience.Public
 @InterfaceStability.Evolving
public enum ExecutionType
extends Enum<ExecutionType>

Container property encoding execution semantics.

The execution types are the following:

• GUARANTEED - this container is guaranteed to start its execution, once the corresponding start container request is received by an NM.
• OPPORTUNISTIC - the execution of this container may not start immediately at the NM that receives the corresponding start container request (depending on the NM's available resources). Moreover, it may be preempted if it blocks a GUARANTEED container from being executed.

Method Detail

values

public static ExecutionType[] values()

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 (ExecutionType c : ExecutionType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ExecutionType 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
