Enum EpochManager.ParallelMode

java.lang.Object

java.lang.Enum<EpochManager.ParallelMode>

org.apache.flink.runtime.asyncprocessing.EpochManager.ParallelMode

All Implemented Interfaces:

Serializable, Comparable<EpochManager.ParallelMode>

Enclosing class:

EpochManager

public static enum EpochManager.ParallelMode
extends Enum<EpochManager.ParallelMode>

This enum defines whether parallel execution between epochs is allowed. We should keep this internal and away from API module for now, until we could see the concrete need for PARALLEL_BETWEEN_EPOCH from average users.

Enum Constant Summary

Enum Constants

Enum Constant	Description
PARALLEL_BETWEEN_EPOCH	Subsequent epochs can begin execution even if the previous epoch has not yet completed.
SERIAL_BETWEEN_EPOCH	Subsequent epochs must wait until the previous epoch is completed before they can start.

Method Summary

Modifier and Type	Method	Description
static EpochManager.ParallelMode	valueOf(String name)	Returns the enum constant of this type with the specified name.
static EpochManager.ParallelMode[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

SERIAL_BETWEEN_EPOCH

public static final EpochManager.ParallelMode SERIAL_BETWEEN_EPOCH

Subsequent epochs must wait until the previous epoch is completed before they can start.

PARALLEL_BETWEEN_EPOCH

public static final EpochManager.ParallelMode PARALLEL_BETWEEN_EPOCH

Subsequent epochs can begin execution even if the previous epoch has not yet completed. Usually performs better than SERIAL_BETWEEN_EPOCH.

Method Detail

values

public static EpochManager.ParallelMode[] 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 (EpochManager.ParallelMode c : EpochManager.ParallelMode.values())
    System.out.println(c);

Returns:

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

valueOf

public static EpochManager.ParallelMode 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
